Road ecology
Transportation systems have inherently dichotomous characteristics.
Roadways and railways provide access to nature, farmland, and urban land.
But they also cause considerable ecological damage to the landscape:
air pollution, water contamination, soil depletion, and wildlife habitat loss and fragmentation.
Principles of road ecology afford the knowledge and applicability to minimize and mitigate the negative impact.
Road ecology integrates an array of disciplines and professions through ecology and landscape ecology.
Road ecology addresses the sustainability of nature as well as the accommodation of vehicles.
Transportation and road ecology must be integrated into urban regional planning, design, and management.
Roads act barriers and fragmenters across the landscape.
But roadsides can function as habitats for wildlife.
Ecologically sensitive planning, design, and management principles from environmental design and engineering include:
grading cutbanks and fillslopes to reduce erosion,
avoiding severe compaction alongside roads,
establishing variety in the adjacent microrelief,
and diminishing the release of chemicals into the air, water, and soil.
Roadside planting design and maintenance should emphasize:
planting of native plant species,
eradication of non-native invasive vegetation,
incorporation of vegetation resistant to air pollutants and water contaminants,
reduction of the need for mowing of grasses,
elimination of or at least reduction of the use of fertilizers, herbicides, and insecticides.
Overall, roadside design should enhance wildlife diversity and societal interactions in the urban, rural, and natural landscapes.
Major effects of roads on the fauna include road mortality as well as habitat loss and separation.
Road mortality tends to be highest among highly mobile and generalist animals
that require multiple resources and are attracted to roads.
Habitat loss most severely affects core-habitat species.
Effects are exacerbated if the species have low reproductive rates, low population densities, extensive habitat requirements.

Avoidance, mitigation, and compensation strategies
The ecological impact of roads can be minimized by avoidance, mitigation, and compensation strategies.
Avoidance can include tunneling the road, changing the route, and eliminating the road.
Mitigation can comprise cleaner fuels, noise reduction berms, wildlife overpasses and underpasses.
Compensation encompasses ecological improvement, offsite but in the proximity of the impact,
related to habitat quality, extent, and connectivity to offset the detrimental effect that cannot be avoided or mitigated.

This study examined the abundance and distribution of native and invasive understory plant species in relation to proximity to roads in Redwood Regional Park in Oakland, California. Abundance was measured using 1.8x1.8 ft quadrants in 19 locations near roads and 19 farther from roads. Statistical analysis found invasive species abundance was higher near roads while native species abundance was higher farther from roads. Distribution of native species was higher farther than 3 km from roads and invasive species distribution was higher within 2 km of roads, rejecting the null hypotheses. Limitations included some unidentified species and a gap in sampling locations.
This document summarizes a capstone project studying the ecological effects of road proximity on a temperate forest ecosystem. The author conducted field surveys using transects at varying distances from a logging road to examine changes in tree species populations and distributions. Preliminary results found the highest diversity closest to the road, which quickly decreased with distance before a slight upward trend out to 50 meters. However, this trend was not strong enough to reject the hypothesis that diversity remains average at each distance. Fewer trees were found on transects perpendicular versus parallel to the road. The study aims to help understand how human development like roads can impact ecosystems by altering species populations.
This document describes a senior research project conducted by Jorge Jamie Gomez at the University of North Florida to determine the efficacy of the UNF Eco-Road in reducing animal road mortalities. The study involved counting animal mortalities on the Eco-Road and an adjacent standard road from September 2011 to August 2012. The results showed that the rate of animal mortalities was significantly lower on the Eco-Road compared to the standard road, providing evidence that Eco-Roads can help reduce animal road deaths. However, future research is still needed to examine reducing mortalities of specific animal species.
The document summarizes a study of invasive plant species found in the Alepu Sand Dunes and marshes along the Bulgarian Black Sea coast. Twelve alien invasive species and four native invasive species were recorded in the area. The most widespread alien species is False indigo (Amorpha fruticosa), while Common reed (Phragmites australis) is the dominant native invasive species. The main routes for the spread of invasive species are proximity to a hotel complex where some species are cultivated, a connecting canal between lakes and dunes, and an adjacent coastal road used by vehicles carrying seeds. The study aims to assess threats posed by invasive species to protected coastal habitats in the area.
The document discusses the major increases in human population and consumption that are putting significant stress on the environment. The growth of the human population from millions to billions in just a few centuries due to technology and medicine is depleting resources and damaging ecosystems. Continued population and economic growth will further degrade the environment unless new technologies can be developed to mitigate these problems. Engineers have a key role to play in measuring environmental impacts, creating sustainable technologies, and helping develop solutions to address the challenges of supporting the human population while protecting the planet.
Badgers & access scientific paper - Jenkinson and Wheater.PDFStephen Jenkinson
This document summarizes a study that examined the impact of public access on badger setts in Bradford, West Yorkshire, UK. The study compared 38 badger setts surveyed in 1985-1986 and again in 1992-1993 to see if they were still in use and the level of illegal disturbance over that period. Key findings were that the number of public access points or their distance from setts did not influence sett persistence. However, setts with less frequent disturbance tended to be closer to more access points and in areas with landowners unsupportive of badger conservation. Setts still in use also tended to be in open areas visible from roads and dwellings.

The topic caters to information needs of waste disposal and landfill. The universal generation of waste has negative consequences on human activities. The study enables understanding of different types of waste and their consequences on human health and environment. . The main purpose of this study is to detail the risk of waste disposal for groundwater quality and entails the information required for assessment of risks. The initial section details about classification of waste and then after, explains storage, treatment and disposal of waste. It has also covered the factors governing contamination of groundwater by disposal of waste for understanding the major concerns of waste composition, leachate production and migration. The final section of study includes assessment of groundwater contamination related to waste sites. The increasing proportion of waste has to control in future and therefore, it is important to study significant aspects of waste disposal and landfill.
Ryan Sclar 232 Term Paper DesertificationRyan Sclar
1) Desertification is the process of fertile land transforming into desert due to factors like climate change and unsustainable human activities. It affects over 2 billion people globally and is responsible for problems like food insecurity.
2) The international community has recognized desertification as a serious issue for decades. Efforts to address it include research programs by UNESCO in the 1950s, and conventions by the UN in the 1970s/90s. However, funding remains low compared to proposed amounts.
3) Most desertification studies and programs have focused on Africa, home to some of the largest drylands. Major initiatives there include drought early warning systems and the Great Green Wall project, aiming to plant trees across the Sah
61; road mortalites of reptiles in the vendeeRoger Meek
This document summarizes a study on patterns of reptile roadkill in western France over four years. The study found that two lizard species (Lacerta bilineata and Podarcis muralis) and two snake species (Hierophis viridiflavus and Natrix natrix) that are more active foragers had higher roadkill rates, while two more sedentary snake species (Vipera aspis and Natrix maura) had lower rates. Roadkills occurred throughout the reptiles' active season, with differences in the size classes and monthly frequencies of some species. A positive correlation was found between monthly roadkill counts and live sightings for H. viridiflavus
This document defines marine pollution and discusses its various types and sources. It notes that 80% of non-biological marine pollution comes from land-based activities like sewage, industrial waste, and agricultural runoff containing pesticides and excess nutrients. Pollutants from land can contaminate ocean water, sediments, and marine life. The document also outlines international frameworks and steps that can be taken to help prevent marine pollution.
- The document discusses the importance of preserving open spaces and vegetation in urban planning to balance environmental, social and economic needs. It notes trees and vegetation provide aesthetic, climatic and engineering benefits.
- It outlines various values and benefits of trees related to architecture, climate, site development and engineering like moderating temperatures, intercepting rainfall, stabilizing soils and reducing pollution. Trees also have economic and legal value by enhancing property values.
- Jurisdictions have enacted preservation ordinances to balance development with resource protection. Successful preservation must integrate into early planning stages rather than be retrofitted later. Proper protection of trees during construction is also important to prevent root damage.
Keith Winning presented on how to use GIS and remote sensing data to select pipeline routes that minimize environmental impacts from soil erosion. GIS can predict erosion risk by analyzing slope, rainfall, soil type, and vegetation cover data to calculate erosion rates along potential routes. Selecting routes with lower erosion risk can reduce construction and maintenance costs while limiting environmental effects like sedimentation in waterways.
Levels of Nitrogen Dioxide and Sulphur Dioxide Measured Around Roadside Garde...Agriculture Journal IJOEAR
Abstract— Levels of nitrogen dioxide and sulphur dioxide around roadside gardens in Port Harcourt metropolis were determined at 0m and 50m from road junctions using portable hand held Multi RAE PLUS (PGM-50), a programmable multi gas monitor with an electrochemical sensor for the detection of Sulphur dioxide and ITX Multi Gas monitor for the detection of Nitrogen dioxide. The results showed that the concentrations of NO2 and SO2 ranged from 0 – 0.3ppm in both seasons. The mean concentration of SO2 at 0m and high traffic density stations were higher than the mean concentration at 50m and low traffic density stations. The difference in mean concentrations between dry and rainy seasons, traffic density and distance were not significant for NO2 but significant for SO2. The concentration of NO2 and SO2 recorded at the study stations exceeded the permissible limits of 0.004ppm and 0.01ppm respectively, recommended by the Federal Ministry of Environment and therefore poses serious threat to the environment particularly small farms and gardens around major roads. The levels of NO2 and SO2 around the gardens were influenced by traffic density, seasonal variations and distances from major roads, therefore authorities should embark on sensitization and enlightenment campaigns; farming activities and raw consumption of exposed vegetables, crops and fruits should be discouraged in the study areas.

Impact of Mulches on Landscape Plants and the
Environment — A Review1
Linda Chalker-Scott2
Washington State University, Puyallup Research and Extension Center
7612 Pioneer Way E., Puyallup, WA 98371
Abstract
Mulches provide aesthetic, economic and environmental benefits to urban landscapes. Mulching is especially useful in the establishment
of trees in landscapes that receive minimal care, such as restoration sites. In general, mulches improve soil health, creating healthy
populations of plants and associated animals. These biodiverse, stable landscapes are more resistant to stress, are more aesthetically
pleasing, require fewer applications of pesticides and fertilizers, and are ultimately more sustainable than those without mulch cover.
All mulches are not created equally, however, and this review compares the costs and benefits of landscape mulches as reported in the
scientific literature. It also presents real and perceived problems associated with various landscape mulches.
Key words: aesthetics, economics, inorganic mulch, living mulch, mulch management, organic mulch, pesticide reduction, plant
establishment, soil protection, urban landscapes.
Significance to the Nursery Industry
There is a vast array of mulch materials available for land-
scape use, benefiting plants and soil ...

The tourism industry in India can have positive and negative environmental impacts. Positively, it can improve environmental management, raise environmental awareness, and contribute to conservation efforts. However, tourism also poses risks such as overusing water resources, producing solid waste and pollution, degrading lands, and reducing biodiversity by disturbing natural habitats. Sustainable tourism development is needed to manage these challenges and preserve India's environment while growing the tourism sector.
Eutrophication is a process where a body of water becomes overly enriched with minerals and nutrients which induces excessive growth of algae. This can result in algal blooms which reduce oxygen in the water by decomposing and can release toxins. Sources of eutrophication include phosphorus and nitrogen from fertilizers and sewage runoff. Long-term eutrophication has damaged ecosystems by decreasing biodiversity and increasing toxicity. Prevention efforts include regulating agricultural runoff and creating buffer zones while cleanup methods involve filtering pollutants.
This document discusses environmental issues and sustainable development in Spain. It covers:
- The concept of sustainable development as stimulating economic growth while safeguarding natural resources.
- How the primary, secondary and tertiary sectors impact the environment through activities like agriculture, industry, tourism and transportation infrastructure.
- Specific environmental problems in Spain like air pollution, uncontrolled urbanization, desertification, and threatened species.
- Protected areas that have been established in Spain to conserve the environment, including national parks, natural reserves, and areas in international agreements or the EU Natura 2000 network.
This document discusses four types of pollution: air, water, noise, and soil. It provides details on each type, including causes and effects. For air pollution, it notes vehicle emissions and energy usage contribute to decreased air quality. Water pollution results from littering and improper chemical disposal contaminating water bodies. Noise pollution stems from transportation and machines interfering with human and animal activities. Soil pollution is caused by industrial chemicals and heavy metals that pose health risks. Throughout, the document emphasizes the importance of conservation and proper waste disposal to prevent environmental degradation from different kinds of pollution.
Nature is under siege. In the last 10,000 y the humanpopulation has grown from 1 million to 7.8 billion.Much of Earth’s arable lands are already in agriculture(1), millions of acres of tropical forest are clearedeach year (2, 3), atmospheric CO2levels are at theirhighest concentrations in more than 3 million y (4), andclimates are erratically and steadily changing frompole to pole, triggering unprecedented droughts,fires, and floods across continents. Indeed, most biol-ogists agree that the world has entered its sixth massextinction event, the first since the end of the Creta-ceous Period 66 million y ago, when more than 80% ofall species, including the nonavian dinosaurs, perished.
Wind erosion can damage crops, buildings, and infrastructure by removing topsoil and nutrients. It can reduce crop yields and negatively impact human health. Soil movement is initiated by wind turbulence and velocity above certain thresholds. Fine particles are transported long distances by wind and deposited when velocities decrease due to obstructions. Controlling wind erosion requires maintaining ground cover through crops, windbreaks, contour plowing, and managing soil moisture.
1) Approximately 51% of households in Cusuco National Park in Honduras are multidimensionally poor, deprived in nearly 45% of basic indicators like electricity, safe water, and assets. Poverty in the park is comparable to rural Honduras.
2) Perceptions of ecosystem services differ between communities in the park, likely due to differences in enforcement of rules and activities. Water provision and climate regulation are highly valued. Agriculture is also important for livelihoods.
3) Community-based management could help address poverty by targeting deprivations, linking conservation to development goals, and providing alternatives to unsustainable land uses and resources like firewood. However, restrictions may reinforce poverty if sustainable alternatives are not
impact of envrmnt on human human activitiesKumar Vikas
The document discusses two topics: 1) The impact of human activities on the environment and ecology, focusing on water pollution, land pollution, air pollution, energy use, and fisheries. 2) The hydrological cycle and precipitation. It describes how precipitation forms, the hydrological cycle of water moving through the atmosphere and environment, and infiltration and runoff processes. It aims to explain these environmental processes and the human impacts on water, land, air, energy resources, and fisheries.
Presentation on climate change by dr. tahmina afrosemuktadirmahin
The document discusses the impacts of climate change on coastal systems and communities. It notes that sea level rise, increased storm intensity, and changes in weather patterns will exacerbate erosion, damage infrastructure, and displace coastal plant and animal communities. Vulnerable areas include densely populated mega deltas, coral reefs, and small islands. Adaptation strategies discussed include protecting coastal zones, accommodating rising seas through land use planning, and developing financial protections like insurance. The document emphasizes the need for coordinated global action to mitigate further climate change through measures like reducing greenhouse gas emissions and transitioning to renewable energy sources.

1) Desertification is the process of fertile land transforming into desert due to factors like climate change and unsustainable human activities. It affects over 2 billion people globally and is responsible for problems like food insecurity.
2) The international community has recognized desertification as a serious issue for decades. Efforts to address it include research programs by UNESCO in the 1950s, and conventions by the UN in the 1970s/90s. However, funding remains low compared to proposed amounts.
3) Most desertification studies and programs have focused on Africa, home to some of the largest drylands. Major initiatives there include drought early warning systems and the Great Green Wall project, aiming to plant trees across the Sah

This document summarizes a study on patterns of reptile roadkill in western France over four years. The study found that two lizard species (Lacerta bilineata and Podarcis muralis) and two snake species (Hierophis viridiflavus and Natrix natrix) that are more active foragers had higher roadkill rates, while two more sedentary snake species (Vipera aspis and Natrix maura) had lower rates. Roadkills occurred throughout the reptiles' active season, with differences in the size classes and monthly frequencies of some species. A positive correlation was found between monthly roadkill counts and live sightings for H. viridiflavus
This document defines marine pollution and discusses its various types and sources. It notes that 80% of non-biological marine pollution comes from land-based activities like sewage, industrial waste, and agricultural runoff containing pesticides and excess nutrients. Pollutants from land can contaminate ocean water, sediments, and marine life. The document also outlines international frameworks and steps that can be taken to help prevent marine pollution.
- The document discusses the importance of preserving open spaces and vegetation in urban planning to balance environmental, social and economic needs. It notes trees and vegetation provide aesthetic, climatic and engineering benefits.
- It outlines various values and benefits of trees related to architecture, climate, site development and engineering like moderating temperatures, intercepting rainfall, stabilizing soils and reducing pollution. Trees also have economic and legal value by enhancing property values.
- Jurisdictions have enacted preservation ordinances to balance development with resource protection. Successful preservation must integrate into early planning stages rather than be retrofitted later. Proper protection of trees during construction is also important to prevent root damage.
Keith Winning presented on how to use GIS and remote sensing data to select pipeline routes that minimize environmental impacts from soil erosion. GIS can predict erosion risk by analyzing slope, rainfall, soil type, and vegetation cover data to calculate erosion rates along potential routes. Selecting routes with lower erosion risk can reduce construction and maintenance costs while limiting environmental effects like sedimentation in waterways.
Levels of Nitrogen Dioxide and Sulphur Dioxide Measured Around Roadside Garde...Agriculture Journal IJOEAR
Abstract— Levels of nitrogen dioxide and sulphur dioxide around roadside gardens in Port Harcourt metropolis were determined at 0m and 50m from road junctions using portable hand held Multi RAE PLUS (PGM-50), a programmable multi gas monitor with an electrochemical sensor for the detection of Sulphur dioxide and ITX Multi Gas monitor for the detection of Nitrogen dioxide. The results showed that the concentrations of NO2 and SO2 ranged from 0 – 0.3ppm in both seasons. The mean concentration of SO2 at 0m and high traffic density stations were higher than the mean concentration at 50m and low traffic density stations. The difference in mean concentrations between dry and rainy seasons, traffic density and distance were not significant for NO2 but significant for SO2. The concentration of NO2 and SO2 recorded at the study stations exceeded the permissible limits of 0.004ppm and 0.01ppm respectively, recommended by the Federal Ministry of Environment and therefore poses serious threat to the environment particularly small farms and gardens around major roads. The levels of NO2 and SO2 around the gardens were influenced by traffic density, seasonal variations and distances from major roads, therefore authorities should embark on sensitization and enlightenment campaigns; farming activities and raw consumption of exposed vegetables, crops and fruits should be discouraged in the study areas.

Impact of Mulches on Landscape Plants and the
Environment — A Review1
Linda Chalker-Scott2
Washington State University, Puyallup Research and Extension Center
7612 Pioneer Way E., Puyallup, WA 98371
Abstract
Mulches provide aesthetic, economic and environmental benefits to urban landscapes. Mulching is especially useful in the establishment
of trees in landscapes that receive minimal care, such as restoration sites. In general, mulches improve soil health, creating healthy
populations of plants and associated animals. These biodiverse, stable landscapes are more resistant to stress, are more aesthetically
pleasing, require fewer applications of pesticides and fertilizers, and are ultimately more sustainable than those without mulch cover.
All mulches are not created equally, however, and this review compares the costs and benefits of landscape mulches as reported in the
scientific literature. It also presents real and perceived problems associated with various landscape mulches.
Key words: aesthetics, economics, inorganic mulch, living mulch, mulch management, organic mulch, pesticide reduction, plant
establishment, soil protection, urban landscapes.
Significance to the Nursery Industry
There is a vast array of mulch materials available for land-
scape use, benefiting plants and soil ...

The tourism industry in India can have positive and negative environmental impacts. Positively, it can improve environmental management, raise environmental awareness, and contribute to conservation efforts. However, tourism also poses risks such as overusing water resources, producing solid waste and pollution, degrading lands, and reducing biodiversity by disturbing natural habitats. Sustainable tourism development is needed to manage these challenges and preserve India's environment while growing the tourism sector.
Eutrophication is a process where a body of water becomes overly enriched with minerals and nutrients which induces excessive growth of algae. This can result in algal blooms which reduce oxygen in the water by decomposing and can release toxins. Sources of eutrophication include phosphorus and nitrogen from fertilizers and sewage runoff. Long-term eutrophication has damaged ecosystems by decreasing biodiversity and increasing toxicity. Prevention efforts include regulating agricultural runoff and creating buffer zones while cleanup methods involve filtering pollutants.
This document discusses environmental issues and sustainable development in Spain. It covers:
- The concept of sustainable development as stimulating economic growth while safeguarding natural resources.
- How the primary, secondary and tertiary sectors impact the environment through activities like agriculture, industry, tourism and transportation infrastructure.
- Specific environmental problems in Spain like air pollution, uncontrolled urbanization, desertification, and threatened species.
- Protected areas that have been established in Spain to conserve the environment, including national parks, natural reserves, and areas in international agreements or the EU Natura 2000 network.
This document discusses four types of pollution: air, water, noise, and soil. It provides details on each type, including causes and effects. For air pollution, it notes vehicle emissions and energy usage contribute to decreased air quality. Water pollution results from littering and improper chemical disposal contaminating water bodies. Noise pollution stems from transportation and machines interfering with human and animal activities. Soil pollution is caused by industrial chemicals and heavy metals that pose health risks. Throughout, the document emphasizes the importance of conservation and proper waste disposal to prevent environmental degradation from different kinds of pollution.
Nature is under siege. In the last 10,000 y the humanpopulation has grown from 1 million to 7.8 billion.Much of Earth’s arable lands are already in agriculture(1), millions of acres of tropical forest are clearedeach year (2, 3), atmospheric CO2levels are at theirhighest concentrations in more than 3 million y (4), andclimates are erratically and steadily changing frompole to pole, triggering unprecedented droughts,fires, and floods across continents. Indeed, most biol-ogists agree that the world has entered its sixth massextinction event, the first since the end of the Creta-ceous Period 66 million y ago, when more than 80% ofall species, including the nonavian dinosaurs, perished.
Wind erosion can damage crops, buildings, and infrastructure by removing topsoil and nutrients. It can reduce crop yields and negatively impact human health. Soil movement is initiated by wind turbulence and velocity above certain thresholds. Fine particles are transported long distances by wind and deposited when velocities decrease due to obstructions. Controlling wind erosion requires maintaining ground cover through crops, windbreaks, contour plowing, and managing soil moisture.
1) Approximately 51% of households in Cusuco National Park in Honduras are multidimensionally poor, deprived in nearly 45% of basic indicators like electricity, safe water, and assets. Poverty in the park is comparable to rural Honduras.
2) Perceptions of ecosystem services differ between communities in the park, likely due to differences in enforcement of rules and activities. Water provision and climate regulation are highly valued. Agriculture is also important for livelihoods.
3) Community-based management could help address poverty by targeting deprivations, linking conservation to development goals, and providing alternatives to unsustainable land uses and resources like firewood. However, restrictions may reinforce poverty if sustainable alternatives are not
impact of envrmnt on human human activitiesKumar Vikas
The document discusses two topics: 1) The impact of human activities on the environment and ecology, focusing on water pollution, land pollution, air pollution, energy use, and fisheries. 2) The hydrological cycle and precipitation. It describes how precipitation forms, the hydrological cycle of water moving through the atmosphere and environment, and infiltration and runoff processes. It aims to explain these environmental processes and the human impacts on water, land, air, energy resources, and fisheries.
Presentation on climate change by dr. tahmina afrosemuktadirmahin
The document discusses the impacts of climate change on coastal systems and communities. It notes that sea level rise, increased storm intensity, and changes in weather patterns will exacerbate erosion, damage infrastructure, and displace coastal plant and animal communities. Vulnerable areas include densely populated mega deltas, coral reefs, and small islands. Adaptation strategies discussed include protecting coastal zones, accommodating rising seas through land use planning, and developing financial protections like insurance. The document emphasizes the need for coordinated global action to mitigate further climate change through measures like reducing greenhouse gas emissions and transitioning to renewable energy sources.

Read Chapter 2 first. Then come to this assignment.
The first theme of next week's class (Week 2) will be Chapter 2, Concepts of Infectious Disease. I will briefly go through the chapter to make sure that you understand it, and then we will have a discussion.
Since the chapter in the textbook is so full of important concepts, it would be difficult to narrow it down to a single topic for discussion. So I have posted this introduction and 3 separate subtopics. You can choose which one you want to write about. Each student should choose one of these subtopics for your major post. You should write well thought out primary comments on at least one of the points below (150-200 words).
BE SURE TO INCLUDE YOUR NAME AND SUBTOPIC IN THE HEADER FOR YOUR PAPER.
We will discuss each of the subtopics that were chosen by the students. Each of you should take an active role in presenting your topic to the other students. Explain the concept in your own words, or develop it further using a relevant example. As other students present their perspective on the same topic, hopefully an active discussion will take hold. I will jump in only as needed. This format will allow you to develop one subtopic in an active sense, but learn about the others by being drawn into them through other people's discussions.
Choose your subtopic:
Subtopic 1: Factors that affect the spread of epidemics
Question: Explain how the interaction between these factors are relevant to the transmission of AIDS. For example, which of these factors are most critical to the transmission of HIV. Which aren't.
1. Total number of hosts
2. Host’s birth rate
3. Rate at which new susceptible hosts migrate into population
4. Number of susceptible uninfected hosts
5. Rate at which disease can be transmitted from infected to uninfected hosts
6. Death rate of infected hosts
7. The number of infected hosts who survive and become immune or resistant to further infection
Subtopic 2: Acute versus Chronic Infections
Question: Compare the definitions of Acute Infections and Chronic Infections below. Based on what you know about HIV/AIDS at this point, which description most closely matches AIDS? Explain your answer, using evidence from the book to support your position.
What is an acute infection?
1. Produces symptoms and makes a person infectious soon after infection.
2. The infected person may: transmit the disease
die from the infection
recover and develop immunity
3. the acute microorganism
STRIKES QUICKLY
infects entire group (small group)
dies out
What is a chronic infection?

Person continues to carry infectious agent at a low level
Does NOT mount an effective immune response

Teaching Grammar and Editing in Public
Administration: Lessons Learned from
Early Offerings of an Undergraduate
Administrative Writing Course
Claire Connolly Knox
University of Central Florida School of Public Administration
ABSTRACT
College graduates need to possess strong writing skills before entering the work-
force. Although many public administration undergraduate programs primarily
focus on policy, finance, and management, we fall short of a larger goal if students
cannot communicate results to a variety of audiences. This article discusses the
results of a national survey, which concludes that few undergraduate public affairs
programs require an administrative/technical writing course. Based on pedagogical
theories, this article describes the design of a newly implemented, undergraduate,
administrative writing course. The article concludes with lessons learned, provides
recommendations for programs considering requiring an administrative writing
course, and discusses future research.
Keywords: administrative writing, Plain Language Movement, discourse community,
undergraduate course design
“Administrators not only need to know about communications, they need to
be able to communicate” (Denhardt, 2001, p. 529). Public administration under-
graduate students learn the importance of communication within organizations
in leadership, human resources, or organizational management courses; however,
practical instruction in communication skills, such as effective, audience-centered
writing, are lacking. Scholars (e.g., Cleary, 1990, 1997; Lee, 2000; Raphael &
Nesbary, 2005; Waugh & Manns, 1991) have noted this lack of required commun-
ication and writing courses in public administration curriculum. The majority of
administrative writing literature is from the late 1980s and early 1990s when
universities began implementing Writing Across the Curriculum programs (i.e.,
JPAE 19 (3), 515–536
516 Journal of Public Affairs Education
Londow, 1993; Stanford, 1992). The limited discussions and conclusions coincide
with private and public sector trends—newly hired students’ writing skills are
lacking (Hines & Basso, 2008; National Commission, 2005).
A survey by the National Commission on Writing for America’s Families,
Schools, and Colleges (2005) reported that approximately 80% of public sector
human resource directors seriously considered writing skills when hiring professional
employees and assumed new employees obtained these skills in college. Increasingly,
public managers require employees to attend writing and communication trainings,
which cost governments approximately $221 million annually (National Commis-
sion, 2005). In fact, the public sector (66%) is more likely to send professional/
salaried employees for writing training than the private sector (40%; National
Commission, 2005). Public, private, and nonprofit sector organizations certainly
should cont ...

The Tauber Manufacturing Institute (TMI) is a partnership between the engineering and business schools at
the University of Michigan. In the summer of 1999, a TMI team spent 14 weeks at Dell Inc. in Austin, Texas,
and developed an inventory model to identify inventory drivers and quantify target levels for inventory in the
final stage of Dell's supply chain, the revolvers or supplier logistics centers (SLC). With the information and
analysis provided by this model, Dell's regional materials organizations could tactically manage revolver inven
tory while Dell's worldwide commodity management could partner with suppliers in improvement projects to
identify inventory drivers and to reduce inventory. Dell also initiated a pilot program for procurement of XDX
(a disguised name for one of the major components of personal computers (PCs)) in the United States to insti
tutionalize the model and promote partnership with suppliers. Based on the model predictions, Dell launched
e-commerce and manufacturing initiatives with its suppliers to lower supply-chain-inventory costs by reducing
revolver inventory by 40 percent. This reduction would raise the corresponding inventory turns by 67 percent.
Net Present Value (NPV) calculations for XDX alone suggest $43 million in potential savings. To ensure project
longevity, Dell formed ...
It’s Your Choice 10 – Clear Values: 2nd Chain Link- Trade-offs - Best Chance of Getting the Most of What You Want.
Narrator: In today's episode, what do I really want? Roger and Nicole discussed the importance of being clear about your values when making a decision in order to give you the best chance of making the most of what you really want. When you understand what you care most about, you can determine which outcomes you prefer as a result of the decision. And, while we frequently can't get everything we want, making tradeoffs is easier when we are clear about our values. Roger: Nicole is something wrong? Nicole: Oh no, not really. I'm just kind of distracted today. See, I finally decided to bite the bullet and buy a car, but I'm having a lot of trouble deciding what to buy. I've been saving for years and I want to make sure I do this right. The problem is that I don't even know where to start. There are so many good cars out there. Roger: I know how tough it can be to try and figure out what you really want it, but you're in luck. On today's show, we're going to be talking about why being clear on your values is so important when making a decision. Nicole: A value is something you want as a result of the decision. Roger: Like when I was trying to decide which college to go to, some of my preferences were to go to a place with a good music program and a D-three basketball team. Nicole: It's funny because when I was looking for a school, I didn't care at all about the basketball team. I was much more interested in theater groups. Roger: and that's fine because values are completely up to the person making the decision. What I want will probably be different from what you want, but I use my values for my decisions and you will use yours for yours. Nicole: I was thinking about asking my friends for their opinions too. Roger: It can be very useful to get input from other people, especially when they're knowledgeable. Just be careful they don't try and talk you into what they want instead of what you wanted. Anyway, have you thought about the things you want the most from the car of your choice? Nicole: Oh sure. There are lots of things like I really want a car I can afford, that gets good gas mileage and is cute safe, a good size and comfortable for my friends. Roger: That's a good start. How about the things you don't want?
Nicole: Well, it has to be reliable. I'll be in a mess if it breaks down. I can't afford a lot of repair bills and I don't want a car that's too big. Roger: That's good. Identifying the things you don't want is just as important as the things you do want. Okay Nicole, now that we have your list, the next step is to ask yourself how important are these things?
Nicole: Well, they're all important.
Roger: Sure, but aren't some more important than others? Nicole: Of course, but I'm not really sure which or which? Roger: A good first step is to identify why something is important to you. For example, is getting good gas ...

Unit Lesson
When founders form companies, they usually focus on the product and the customers they hope to generate.
The founders are usually of the same mindset and intention about what they want their company to do and
how they would like it to grow. What many companies fail to plan for is the inevitable death of one of the
founding members and what that might mean for the vision and purpose of the company. In other words, what
would the management structure resemble if one of the founding partners had to deal with the heir of the
deceased partner?
For example, once, two middle-aged founders focused on the same mission, creating and living by their
cultural values and vision, diligently reaching out to their target market, and productively engaging their
customers. One partner unexpectedly died. After the funeral, the surviving founder finds himself now working
side-by-side with the recently deceased founder’s 17-year-old son or daughter. Very quickly, the surviving

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

The Science of Learning: implications for modern teachingDerek Wenmoth

2. landscapes cause local hydrologic and erosion effects, whereas
stream networks
and distant valleys receive major peak-flow and sediment
impacts. Chemical ef-
fects mainly occur near roads. Road networks interrupt
horizontal ecological
flows, alter landscape spatial pattern, and therefore inhibit
important interior
species. Thus, road density and network structure are
informative landscape
ecology assays. Australia has huge road-reserve networks of
native vegetation,
whereas the Dutch have tunnels and overpasses perforating road
barriers to en-
hance ecological flows. Based on road-effect zones, an
estimated 15–20% of the
United States is ecologically impacted by roads.
INTRODUCTION
Roads appear as major conspicuous objects in aerial views and
photographs,
and their ecological effects spread through the landscape. Few
environmental
scientists, from population ecologists to stream or landscape
ecologists, recog-
nize the sleeping giant, road ecology. This major frontier and its
applications to
planning, conservation, management, design, and policy are
great challenges
for science and society.

This review often refers to The Netherlands and Australia as
world leaders
with different approaches in road ecology and to the United
States for es-
pecially useful data. In The Netherlands, the density of main
roads alone is
1.5 km/km2, with traffic density of generally between 10,000
and 50,000 ve-
hicles per commuter day (101). Australia has nearly 900,000 km
of roads for
18 million people (66). In the United States, 6.2 million km of
public roads
are used by 200 million vehicles (85). Ten percent of the road
length is in
national forests, and one percent is interstate highways. The
road density is
1.2 km/km2, and Americans drive their cars for about 1 h/day.
Road density is
increasing slowly, while vehicle kilometers (miles) traveled
(VMT) is growing
rapidly.
The term road corridor refers to the road surface plus its
maintained roadsides
and any parallel vegetated strips, such as a median strip
between lanes in a
highway (Figure 1; see color version at end of volume).
“Roadside natural
strips” of mostly native vegetation receiving little maintenance
7. and located
adjacent to roadsides are common in Australia (where road
corridors are called
road reserves) (12, 39, 111). Road corridors cover
approximately 1% of the
United States, equal to the area of Austria or South Carolina
(85). However,
the area directly affected ecologically is much greater (42, 43).
Theory for road corridors highlights their functional roles as
conduits, bar-
riers (or filters), habitats, sources, and sinks (12, 39). Key
variables affecting
processes are corridor width, connectivity, and usage intensity.
Network theory,
in turn, focuses on connectivity, circuitry, and node functions
(39, 71).
This review largely excludes road-construction-related
activities, as well
as affiliated road features such as rest stops, maintenance
facilities, and en-
trance/exit areas. We also exclude the dispersed ecological
effects of air pollu-
tion emissions, such as greenhouse gases, nitrogen oxides
(NOX), and ozone,
which are reviewed elsewhere (85, 135). Bennett’s article (12)
plus a series of
books (1, 21, 33, 111) provide overviews of parts of road
ecology.
Gaping holes in our knowledge of road ecology represent
research oppor-
tunities with a short lag between theory and application. Current
ecological
knowledge clusters around five major topics: (a) roadsides and
8. adjacent strips;
(b) road and vehicle effects on populations; (c) water, sediment,
chemicals, and
streams; (d ) the road network; and (e) transportation policy and
planning.

ROADSIDE VEGETATION AND ANIMALS
Plants and Vegetation
“Roadside” or “verge” refers to the more-or-less intensively
15. managed strip,
usually dominated by herbaceous vegetation, adjacent to a road
surface
(Figure 1). Plants on this strip tend to grow rapidly with ample
light and with
moisture from road drainage. Indeed, management often
includes regular mow-
ing, which slows woody-plant invasion (1, 86). Ecological
management may
also maintain roadside native-plant communities in areas of
intensive agricul-
ture, reduce the invasion of exotic (non-native) species, attract
or repel animals,
enhance road drainage, and reduce soil erosion.
Roadsides contain few regionally rare species but have
relatively high plant
species richness (12, 139). Disturbance-tolerant species
predominate, espe-
cially with intensive management, adjacent to highways, and
exotic species
typically are common (19, 121). Roadside mowing tends to both
reduce plant
species richness and favor exotic plants (27, 92, 107).
Furthermore, cutting and
removing hay twice a year may result in higher plant species
richness than does
mowing less frequently (29, 86). Native wildflower species are
increasingly
planted in dispersed locations along highways (1).
Numerous seeds are carried and deposited along roads by
vehicles (70, 112).
Plants may also spread along roads due to vehicle-caused air
turbulence
(107, 133) or favorable roadside conditions (1, 92, 107, 121,
16. 133). For exam-
ple, the short-distance spread of an exotic wetland species,
purple loosestrife
(Lythrum salicaria), along a New York highway was facilitated
by roadside
ditches, as well as culverts connecting opposite sides of the
highway and the
median strip of vegetation (133). Yet few documented cases are
known of
species that have successfully spread more than 1 km because of
roads.
Mineral nutrient fertilization from roadside management, nearby
agriculture,
and atmospheric NOX also alter roadside vegetation. In Britain,
for example,
vegetation was changed for 100–200 m from a highway by
nitrogen from traffic
exhaust (7). Nutrient enrichment from nearby agriculture
enhances the growth
of aggressive weeds and can be a major stress on a roadside
native-plant commu-
nity (19, 92). Indeed, to conserve roadside native-plant
communities in Dutch
farmland, fertilization and importing topsoil are ending, and in
some places
nutrient accumulations and weed seed banks are reduced by soil
removal (86;
H van Bohemen, personal communication).
Woody species are planted in some roadsides to reduce erosion,
control
snow accumulation, support wildlife, reduce headlight glare, or
enhance aes-
thetics (1, 105). Planted exotic species, however, may spread
into nearby natural
17. ecosystems (3, 12). For example, in half the places where non-
native woody
species were planted in roadsides adjacent to woods in
Massachusetts (USA),
a species had spread into the woods (42).

ROADS AND ECOLOGICAL EFFECTS 211
Roadside management sometimes creates habitat diversity to
maintain native
ecosystems or species (1, 86, 131). Mowing different sections
along a road, or
parallel strips in wide roadsides, at different times or intervals
may be quite ef-
fective (87). Ponds, wetlands, ditches, berms, varied roadside
widths, different
sun and shade combinations, different slope angles and
exposures, and shrub
patches rather than rows offer variety for roadside species
richness.
In landscapes where almost all native vegetation has been
removed for cul-
tivation or pasture, roadside natural strips (Figure 1) are
especially valuable as
reservoirs of biological diversity (19, 66). Strips of native
prairie along roads
and railroads, plus so-called beauty strips of woodland that
block views near
intensive logging, may function similarly as examples.
21. However, roadside nat-
ural strips of woody vegetation are widespread in many
Australian agricultural
landscapes and are present in South Africa (11, 12, 27, 39, 66,
111). Overall,
these giant green networks provide impressive habitat
connectivity and disperse
“bits of nature” widely across a landscape. Yet they miss the
greater ecological
benefits typically provided by large patches of natural
vegetation (39, 41).
In conclusion, roadside vegetation is rich in plant species,
although appar-
ently not an important conduit for plants. The scattered
literature suggests a
promising research frontier.
Animals and Movement Patterns
Mowing, burning, livestock grazing, fertilizing, and planting
woody plants
greatly impact native animals in roadsides. Cutting and
removing roadside veg-
etation twice a year in The Netherlands, compared with less
frequent mowing,
results in more species of small mammals, reptiles, amphibians,
and insects
(29, 86). However, mowing once every 3–5 y rather than
annually results
in more bird nests. Many vertebrate species persist better with
mowing af-
ter, rather than before or during, the breeding period (86, 87).
The mowing
regime is especially important for insects such as meadow
butterflies and moths,
where different species go through stages of their annual cycle
22. at different times
(83). Roadsides, especially where mowed cuttings are removed,
are suitable
for ∼80% of the Dutch butterfly fauna (86).
Planting several native and exotic shrub species along Indiana
(USA)
highways resulted in higher species richness, population
density, and nest den-
sity for birds, compared with nearby grassy roadsides (105).
Rabbit (Sylvilagus)
density increased slightly. However, roadkill rates did not differ
next to shrubby
versus grassy roadsides.
In general, road surfaces, roadsides, and adjacent areas are little
used as
conduits for animal movement along a road (39), although
comparisons with
null models are rare. For example, radiotracking studies of
wildlife across the
landscape detect few movements along or parallel to roads (35,
39, 93). Some
exceptions are noteworthy. Foraging animals encountering a
road sometimes
A
nn

26. species move along roads that have little vehicular or people
traffic (12, 39).
Carrion feeders move along roads in search of roadkills, and
vehicles some-
times transport amphibians and other animals (11, 12, 32).
Small mammals
have spread tens of kilometers along highway roadsides (47,
60). In addition,
migrating birds might use roads as navigational cues.
Experimental, observational, and modeling approaches have
been used to
study beetle movement along roadsides in The Netherlands
(125–127). On wide
roadsides, fewer animals disappeared into adjacent habitats.
Also, a dense grass
strip by the road surface minimized beetle susceptibility to
roadkill mortality
(126, 127). Long dispersals of beetles were more frequent in
wide (15–25 m)
than in narrow (<12 m) roadsides. Nodes of open vegetation
increased, and
narrow bottlenecks decreased, the probability of long dispersals.
The results
suggest that with 20–30-m-wide roadsides containing a central
suitable habitat,
beetle species with poor dispersal ability and a good
reproductive rate may
move 1–2 km along roadsides in a decade (127).
Adjacent ecosystems also exert significant influences on
animals in corridors
(39). For example, roadside beetle diversity was higher near a
similar patch
of sandy habitat, and roadsides next to forest had the greatest
number of forest
27. beetle species (127). In an intensive-agriculture landscape
(Iowa, USA), bird-
nest predation in roadsides was highest opposite woods and
lowest opposite
pastures (K Freemark, unpublished data). Finally, some roadside
animals also
invade nearby natural vegetation (37, 47, 54, 60, 63, 127).
The median strip between lanes of a highway is little studied. A
North
Carolina (USA) study found no difference in small-mammal
density between
roadsides on the median and on the outer side of the highway
(2). This result was
the same whether comparing mowed roadside areas or unmowed
roadside areas.
Also, roadkill rates may be affected by the pattern of wooded
and grassy areas
along median strips (10).
In conclusion, some species move significant distances along
roadsides and
have major local impacts. Nevertheless, road corridors appear to
be relatively
unimportant as conduits for species movement, although
movement rates should
be better compared with those at a distance and in natural-
vegetation corridors.
ROAD AND VEHICLE EFFECTS ON POPULATIONS
Roadkilled Animals
Sometime during the last three decades, roads with vehicles
probably overtook
hunting as the leading direct human cause of vertebrate
mortality on land. In
28. addition to the large numbers of vertebrates killed, insects are
roadkilled in
prodigious numbers, as windshield counts will attest.

ROADS AND ECOLOGICAL EFFECTS 213
Estimates of roadkills (faunal casualties) based on
measurements in short
sections of roads tell the annual story (12, 39, 123): 159,000
mammals and
653,000 birds in The Netherlands; seven million birds in
Bulgaria; five million
frogs and reptiles in Australia. An estimated one million
vertebrates per day
are killed on roads in the United States.
Long-term studies of roadkills near wetlands illustrate two
important pat-
terns. One study recorded>625 snakes and another>1700 frogs
annually
roadkilled per kilometer (8, 54). A growing literature suggests
that roads by
wetlands and ponds commonly have the highest roadkill rates,
and that, even
though amphibians may tend to avoid roads (34), the greatest
transportation
impact on amphibians is probably roadkills (8, 28, 34, 128).
Road width and vehicle traffic levels and speeds affect roadkill
rates. Am-
32. phibians and reptiles tend to be particularly susceptible on two-
lane roads with
low to moderate traffic (28, 34, 57, 67). Large and mid-sized
mammals are espe-
cially susceptible on two-lane, high-speed roads, and birds and
small mammals
on wider, high-speed highways (33, 90, 106).
Do roadkills significantly impact populations? Measurements of
bird and
mammal roadkills in England illustrate the main pattern (56,
57). The house
sparrow (Passer domesticus) had by far the highest roadkill rate.
Yet this species
has a huge population, reproduces much faster than the roadkill
rate, and can
rapidly recolonize locations where a local population drops. The
study con-
cluded, based on the limited data sets available, that none of
the>100 bird and
mammal species recorded had a roadkill rate sufficient to affect
population size
at the national level.
Despite this overall pattern, roadkill rates are apparently
significant for a few
species listed as nationally endangered or threatened in various
nations (∼9–
12 cases) (9, 39, 43; C Vos, personal communication). Two
examples from
southern Florida (USA) are illustrative. The Florida panther
(Felis concolor
coryi) had an annual roadkill mortality of approximately 10% of
its population
before 1991 (33, 54). Mitigation efforts reduced roadkill loss to
2%. The key
33. deer (Odocoileus virginianus clavium) has an annual roadkill
mortality of∼16%
of its population. Local populations, of course, may suffer
declines where the
roadkill rate exceeds the rates of reproduction and immigration.
At least a dozen
local-population examples are known for vertebrates whose
total populations
are not endangered (33, 39, 43).
Vehicles often hit vertebrates attracted to spilled grain, roadside
plants, in-
sects, basking animals, small mammals, road salt, or dead
animals (12, 32, 56,
87). Roadkills may be frequent where traffic lanes are separated
by imperme-
able barriers or are between higher roadside banks (10, 106).
Landscape spatial patterns also help determine roadkill
locations and rates.
Animals linked to specific adjacent land uses include
amphibians roadkilled

near wetlands and turtles near open-water areas (8). Foraging
deer are often
roadkilled between fields in forested landscapes, between
wooded areas in
open landscapes, or by conservation areas in suburbs (10, 42,
37. 106). The vicinity
of a large natural-vegetation patch and the area between two
such patches are
likely roadkill locations for foraging or dispersing animals.
Even more likely
locations are where major wildlife-movement routes are
interrupted, such as
roads crossing drainage valleys in open landscapes or crossing
railway routes
in suburbs (42, 106).
In short, road vehicles are prolific killers of terrestrial
vertebrates. Neverthe-
less, except for a small number of rare species, roadkills have
minimal effect
on population size.
Vehicle Disturbance and Road Avoidance
The ecological effect of road avoidance caused by traffic
disturbance is probably
much greater than that of roadkills seen splattered along the
road. Traffic noise
seems most important, although visual disturbance, pollutants,
and predators
moving along a road are alternative hypotheses as the cause of
avoidance.
Studies of the ecological effects of highways on avian
communities in The
Netherlands point to an important pattern. In both woodlands
and grasslands
adjacent to roads, 60% of the bird species present had a lower
density near a
highway (102, 103). In the affected zone, the total bird density
was approxi-
mately one third lower, and species richness was reduced as
38. species progres-
sively disappeared with proximity to the road. Effect-distances
(the distance
from a road at which a population density decrease was
detected) were greatest
for birds in grasslands, intermediate for birds in deciduous
woods, and least for
birds in coniferous woods.
Effect-distances were also sensitive to traffic density. Thus,
with an average
traffic speed of 120 km/h, the effect-distances for the most
sensitive species
(rather than for all species combined) were 305 m in woodland
by roads with
a traffic density of 10,000 vehicles per day (veh/day) and 810 m
in woodland by
50,000 veh/day; 365 m in grassland by 10,000 veh/day and 930
m in grassland
by 50,000 veh/day (101–103). Most grassland species showed
population de-
creases by roads with 5000 veh/day or less (102). The effect-
distances for both
woodland and grassland birds increased steadily with average
vehicle speed
up to 120 km/h and also with traffic density from 3000 to
140,000 veh/day
(100, 102, 103). These road effects were more severe in years
when overall bird
population sizes were low (101).
Songbirds appear to be sensitive to remarkably low noise levels,
similar to
those in a library reading room (100, 102, 103). The noise level
at which popula-
tion densities of all woodland birds began to decline averaged
39. 42 decibels (dB),
compared with an average of 48 dB for grassland species. The
most sensitive

woodland species (cuckoo) showed a decline in density at 35
dB, and the
most sensitive grassland bird (black-tailed godwit,Limosa
limosa) responded
at 43 dB. Field studies and experiments will help clarify the
significance of
these important results for traffic noise and birds.
Many possible reasons exist for the effects of traffic noise.
Likely hypotheses
include hearing loss, increase in stress hormones, altered
behaviors, interfer-
ence with communication during breeding activities, differential
sensitivity to
different frequencies, and deleterious effects on food supply or
other habitat at-
tributes (6, 101, 103, 130). Indeed, vibrations associated with
traffic may affect
the emergence of earthworms from soil and the abundance of
crows (Corvus)
feeding on them (120). A different stress, roadside lighting,
altered nocturnal
frog behavior (18). Responses to roads with little traffic may
resemble behav-
43. ioral responses to acute disturbances (individual vehicles
periodically passing),
rather than the effects of chronic disturbance along busy roads.
Response to traffic noise is part of a broader pattern of road
avoidance by
animals. In the Dutch studies, visual disturbance and pollutants
extended out-
ward only a short distance compared with traffic noise (100,
103). However,
visual disturbance and predators moving along roads may be
more significant
by low-traffic roads.
Various large mammals tend to have lower population densities
within
100–200 m of roads (72, 93, 108). Other animals that seem to
avoid roads in-
clude arthropods, small mammals, forest birds, and grassland
birds (37, 47, 73,
123). Such road-effect zones, extending outward tens or
hundreds of meters
from a road, generally exhibit lower breeding densities and
reduced species rich-
ness compared with control sites (32, 101). Considering the
density of roads
plus the total area of avoidance zones, the ecological impact of
road avoidance
must well exceed the impact of either roadkills or habitat loss in
road corridors.
Barrier Effects and Habitat Fragmentation
All roads serve as barriers or filters to some animal movement.
Experiments
show that carabid beetles and wolf spiders (Lycosa) are blocked
by roads as
44. narrow as 2.5 m wide (73), and wider roads are significant
barriers to crossing for
many mammals (11, 54, 90, 113). The probability of small
mammals crossing
lightly traveled roads 6–15 m wide may be<10% of that for
movements within
adjacent habitats (78, 119). Similarly, wetland species,
including amphibians
and turtles, commonly show a reduced tendency to cross roads
(34, 67).
Road width and traffic density are major determinants of the
barrier effect,
whereas road surface (asphalt or concrete versus gravel or soil)
is generally
a minor factor (34, 39, 73, 90). Road salt appears to be a
significant deterrent
to amphibian crossing (28, 42). Also, lobes and coves in
convoluted outer-
roadside boundaries probably affect crossing locations and rates
(39).

The barrier effect tends to create metapopulations, e.g. where
roads divide
a large continuous population into smaller, partially isolated
local populations
(subpopulations) (6, 54, 128). Small populations fluctuate more
widely over
48. time and have a higher probability of extinction than do large
populations
(1, 88, 115, 122, 123). Furthermore, the recolonization process
is also blocked
by road barriers, often accentuated by road widening or
increases in traffic. This
well-known demographic threat must affect numerous species
near an extensive
road network, yet is little studied relative to roads (6, 73, 98).
The genetics of a population is also altered by a barrier that
persists over many
generations (73, 115). For instance, road barriers altered the
genetic structure
of small local populations of the common frog (Rana
temporaria) in Germany
by lowering genetic heterozygosity and polymorphism (97, 98).
Other than the
barrier effect on this amphibian and roadkill effects on two
southern Florida
mammals (20, 54), little is known of the genetic effects of
roads.
Making roads more permeable reduces the demographic threat
but at the
cost of more roadkills. In contrast, increasing the barrier effect
of roads re-
duces roadkills but accentuates the problems of small
populations. What is the
solution to this quandary (122, 128)? The barrier effect on
populations proba-
bly affects more species, and extends over a wider land area,
than the effects
of either roadkills or road avoidance. This barrier effect may
emerge as the
greatest ecological impact of roads with vehicles. Therefore,
49. perforating roads
to diminish barriers makes good ecological sense.
WATER, SEDIMENT, CHEMICALS, STREAMS,
AND ROADS
Water Runoff
Altering flows can have major physical or chemical effects on
aquatic ecosys-
tems. The external forces of gravity and resistance cause
streams to carve chan-
nels, transport materials and chemicals, and change the
landscape (68). Thus,
water runoff and sediment yield are the key physical processes
whereby roads
have an impact on streams and other aquatic systems, and the
resulting effect-
distances vary widely (Figure 2).
Roads on upper hillslopes concentrate water flows, which in
turn form chan-
nels higher on slopes than in the absence of roads (80). This
process leads to
smaller, more elongated first-order drainage basins and a longer
total length
of the channel network. The effects of stream network length on
erosion and
sedimentation vary with both scale and drainage basin area (80).
Water rapidly runs off relatively impervious road surfaces,
especially in storm
and snowmelt events. However, in moist, hilly, and
mountainous terrain, such

runoff is often insignificant compared with the conversion of
slow-moving
groundwater to fast-moving surface water at cutbanks by roads
(52, 62, 132).
Surface water is then carried by roadside ditches, some of which
connect di-
rectly to streams while others drain to culverts with gullies
incised below their
outlets (132). Increased runoff associated with roads may
increase the rates and
extent of erosion, reduce percolation and aquifer recharge rates,
alter channel
morphology, and increase stream discharge rates (13, 14). Peak
discharges or

57. floods then restructure riparian areas by rearranging channels,
logs, branches,
boulders, fine-sediment deposits, and pools.
In forests, the combination of logging and roads increases peak
discharges
and downstream flooding (62, 132). Forest removal results in
lower evapo-
transpiration and water-storage capabilities, but roads alone
may increase peak
discharge rates (62). Also, flood frequency apparently correlates
with the per-
centage of road cover in a basin (52, 62, 110).
Roads may alter the subsurface flow as well as the surface flow
on wetland
soils (116). Compacted saturated or nearly saturated soils have
limited perme-
ability and low drainage capacity. Wetland road crossings often
block drainage
passages and groundwater flows, effectively raising the upslope
water table and
killing vegetation by root inundation, while lowering the
downslope water table
with accompanying damage to vegetation (116, 118).
Streams may be altered for considerable distances both
upstream and down-
stream of bridges. Upstream, levees or channelization tend to
result in reduced
flooding of the riparian zone, grade degradation, hydraulic
structural problems,
and more channelization (17). Downstream, the grade change at
a bridge results
in local scouring that alters sedimentation and deposition
processes (17, 49).
58. Sediment and chemicals enter streams where a road crosses, and
mathemati-
cal models predict sediment loading in and out of reaches
affected by stream
crossings (5). The fixed stream (or river) location at a bridge or
culvert re-
duces both the amount and variability of stream migration
across a floodplain.
Therefore, stream ecosystems have altered flow rates, pool-
riffle sequences, and
scour, which typically reduce habitat-forming debris and
aquatic organisms.
Sediment
The volume of sediment yield from a road depends on sediment
supply and
transport capacity (5). Sediment yield is determined by road
geometry, slope,
length, width, surface, and maintenance (5, 51), in addition to
soil properties and
vegetation cover (59). Road surfaces, cutbanks, fillslopes,
bridge/culvert sites,
and ditches are all sources of sediment associated with roads.
The exposed
soil surfaces, as well as the greater sediment-transport capacity
of increased
hydrologic flows, result in higher erosion rates and sediment
yields (99).
Road dust as a little-studied sediment transfer may directly
damage vegeta-
tion, provide nutrients for plant growth, or change the pH and
vegetation (109).
Effect-distances are usually<10–20 m but may extend to 200 m
downwind
(Figure 2). In arid land, soil erosion and drainage are common
59. road problems
(61).
Arctic roads also are often sources of dust. Other ecological
issues include
change in albedo, flooding, erosion and thermokarst, weed
migration, waterfowl
and shorebird habitat, and altered movement of large mammals
(129).

ROADS AND ECOLOGICAL EFFECTS 219
Landsliding or mass wasting associated with roads may be a
major sediment
source (13, 117). Some of this sediment accumulates on lower
slopes and is
subject to subsequent erosion. The rest reaches floodplains or
streams, where it
alters riparian ecosystems, channel morphology, or aquatic
habitat. Although
gradual sediment transport and episodic landslides are natural
processes affect-
ing streams, elevated levels caused by roads tend to disrupt
aquatic ecosystems.
Indeed, logging roads commonly produce more erosion and
sediment yield,
particularly by mass wasting, than do the areas logged (45, 51,
104, 117).
Buffer strips between roads and streams tend to reduce
63. sediments reaching
aquatic ecosystems (77, 91). Buffers may be less effective for
landslides than
for arresting water and sediment from culverts and roadside
ditches. Good
road location (including avoiding streamsides and narrow
floodplains for many
ecological reasons), plus good ecological design of roadsides
relative to slope,
soil, and hydrology, may be a better strategy than depending on
wide buffers to
absorb sediment.
Water from road ditches tends to deposit finer sediment in
streams, whereas
landslides generally provide coarser material. Fine sediment
increases turbidity
(51), which disrupts stream ecosystems in part by inhibiting
aquatic plants,
macro-invertebrates, and fish (14, 16, 31, 99). Coarse deposits
such as logs and
boulders help create deep pools and habitat heterogeneity in
streams. During
low-flow periods, fine-sediment deposits tend to fill pools and
smooth gravel
beds, hence degrading habitats and spawning sites for key fish
(13, 14, 31).
During high-discharge events, accumulated sediment tends to be
flushed out
and redeposited in larger water bodies.
In short, roads accelerate water flows and sediment transport,
which raise
flood levels and degrade aquatic ecosystems. Thus, local
hydrologic and erosion
effects along roads are dispersed across the land, whereas major
64. impacts are
concentrated in the stream network and distant valleys.
Chemical Transport
Most chemical transport from roads occurs in stormwater runoff
through or
over soil. Runoff pollutants alter soil chemistry, may be
absorbed by plants,
and affect stream ecosystems, where they are dispersed and
diluted over con-
siderable distances (16, 50, 66, 137, 138). Deicing salt and
heavy metals are the
two main categories of pollutants studied in road runoff.
The primary deicing agent, NaCl, corrodes vehicles and bridges,
contami-
nates drinking water supplies, and is toxic to many species of
plants, fish, and
other aquatic organisms (4, 16, 84). Calcium magnesium acetate
(CMA) is a
more effective deicer, less corrosive, less mobile in soil,
biodegradable, and
less toxic to aquatic organisms (4, 84, 89). Also, CaCl used to
decrease dust
may inhibit amphibian movement (28).

68. Pinus strobus) up to 120 m from a road, especially downwind
and downslope
(58, 84). Trees seem to be more sensitive to chloride damage
than are common
roadside shrubs and grasses. Sodium accumulation in soils,
mainly within 5 m
of a road, alters soil structure, which affects plant growth (84).
Road salt has
facilitated the spread of three coastal exotic plants as much as
150 km in The
Netherlands (1).
Deicing agents tend to increase the mobility of chemical
elements in soil, such
as heavy metals (by NaCl) and Na, Cl, Ca, and Mg (by CMA)
(4). This process
facilitates contamination of groundwater, aquifers, and streams.
Because of
dilution, the chemical effects of road runoff on surface water
ecosystems may
be primarily confined to small streams, particularly where they
run adjacent to
roads (36, 84).
Heavy metals are relatively immobile and heterogeneously
distributed in
roadsides, especially due to drainage ditch flows (15, 55, 80).
Soils adjacent to
the road surface typically contain the greatest mass (136).
Elevated concentra-
tions in grass tissue may occur within 5–8 m of a road, although
high lead levels
have been found in soil out to 25 m (30, 65, 82). Elevated lead
concentrations
were found in tissue of several small-mammal species in a
narrow zone by
69. roads, with higher lead levels by busy roads (48).
Highway roadsides of 5–15-m width next to traffic densities of
11,000–
124,000 veh/day in The Netherlands had somewhat higher
heavy-metal accu-
mulations on the downwind side, but no correlation with traffic
density was
found (30). All average levels of Pb, Cd, Zn, Cr, Ni, and As in
cut grass
(hay) from these roadsides were below the Dutch maximum-
acceptable-levels
for livestock fodder and “clean compost.” Only Zn in some
roadsides studied
exceeded the maximum for “very clean compost.”
Many other chemicals enter roadsides. Herbicides often kill
non-target plants,
particularly from blanket applications in drifting air. For
polycyclic aromatic
hydrocarbons from petroleum (136), the preliminary conclusion
for the Dutch
highways was that levels in roadside hay “do not seem to give
cause for alarm”
(30). Fertilizer nutrients affect roadside vegetation (19, 86, 92),
and nitrogen
from vehicular NOX emission altered vegetation up to 100–200
m from a high-
way in Britain (7). Acidic road runoff may have impacts on
stream ecosystems
(36, 81). Of the hazardous materials transported on roads,
e.g.>500,000 ship-
ments moved each day in the United States, a small fraction is
spilled, although
occasional large spills cause severe local effects (85).
70. Typical water-quality responses to road runoff include altered
levels of heavy
metal, salinity, turbidity, and dissolved oxygen (16, 23, 81).
However, these
water-quality changes, even in a wetland, tend to be temporary
and localized
due to fluctuations in water quantity (23). Road runoff is a
major source of heavy

metals to stream systems, especially Pb, Zn, Cu, Cr, and Cd (16,
50, 64, 137).
Fish mortality in streams has been related to high
concentrations of Al, Mn, Cu,
Fe, or Zn, with effects on populations reorded as far as 8 km
downstream (81).
Both high traffic volume and high metal concentration in runoff
have correlated
with mortality of fish and other aquatic organisms (59).
Floodplain soil near
bridges may have high heavy-metal concentrations (138).
Although highway
runoff generally has little adverse effect on vegetation or plant
productivity, it
may change the species composition of floodplain plant
communities, favoring
common species (138).
Overall, terrestrial vegetation seems to be more resistant than
74. aquatic organ-
isms to road impacts (59, 138). Drainage of road runoff through
grassy channels
greatly reduces toxic solid- and heavy-metal concentrations
(59). Furthermore,
dense vegetation increases soil infiltration and storage.
Therefore, instead of
expensive detention ponds and drainage structures to reduce
runoff impacts,
creative grassland designs by roads, perhaps with shrubs, may
provide both
sponge and biodiversity benefits. The wide range of studies
cited above lead to
the conclusion that chemical impacts tend to be localized near
roads.
THE ROAD NETWORK
New Roads and Changing Landscape Pattern
Do roads lead to development, or does development lead to
roads? This timeless
debate in the transportation community has greater
ramifications as environ-
mental quality becomes more important in the transportation–
land-use inter-
action (114). For example, new roads into forested landscapes
often lead to
economic development as well as deforestation and habitat
fragmentation (22).
At the landscape scale, the major ecological impacts of a road
network are the
disruption of landscape processes and loss of biodiversity.
Interrupting hori-
zontal natural processes, such as groundwater flow, streamflow,
fire spread, for-
75. aging, and dispersal, fundamentally alters the way the landscape
works (40, 53).
It truncates flows and movements, and reduces the critical
variability in natural
processes and disturbances. Biodiversity erodes as the road
network impacts
interior species, species with large home ranges, stream and
wetland species,
rare native species, and species dependent on disturbance and
horizontal flows.
A new road system in the Rondonia rainforest of Brazil
illustrates such
effects. By 1984, road construction and asphalt paving had
stimulated a major
influx of people and forest clearing (25). A regular pattern of
primary roads
plus parallel secondary roads 4 km apart was imposed on the
land. Commonly,
small forest plots of∼5 ha were gradually converted to grass
and joined with
neighboring plots to form large pastures (26). Simulation
models of this typical
scenario were compared with models of a worst-case scenario
and an “innovative

79. Species requiring a large area and having poor “gap-
crossability” disappeared
in all model scenarios after road construction. Species with
moderate require-
ments for area and gap-crossability persisted only in the
innovative farming
scenario. Reestablishing the connectivity of nature with a
network of wildlife
corridors was proposed as a solution to maintain the first group
of species,
which are of conservation importance.
The closure and removal of some roads in the grid is an
alternative ecological
approach. Natural landscape processes and biodiversity are both
inhibited by
a rigid road grid. Closing and eliminating some linkages would
permit the
reestablishment of a few large patches of natural rainforest (39,
41, 43). Such a
solution helps create a road network with a high variance in
mesh size. Large
natural-vegetation patches in areas remote from both roads and
people are
apparently required to sustain important species such as wolf,
bear, and probably
jaguar (Canis lupus, Ursus, Felis onca) (39, 76). Temporary
road closures could,
for example, enhance amphibian migration during the breeding
phase (67). In
contrast, road closure and removal could eliminate motorized
vehicle use, thus
reducing numerous disturbance effects on natural populations
and ecosystems.
A general spatial-process model emphasizes that roads have the
80. greatest eco-
logical impact early in the process of land transformation (39,
41). They dissect
the land, leading to habitat fragmentation, shrinkage, and
attrition. Forest road
networks may also create distinctive spatial patterns, such as
converting con-
voluted to rectilinear shapes, decreasing core forest area, and
creating more
total edge habitat by roads than by logged areas (79, 96).
Forest roads as a subset of roads in general are characterized as
being narrow,
not covered with asphalt, lightly traveled, and remote (98).
Among the wide
range of ecological effects of roads (39, 95), forest roads have a
distinctive set
of major ecological effects: (a) habitat loss by road
construction, (b) altered
water routing and downstream peak flows, (c) soil erosion and
sedimentation
impacts on streams, (d ) altered species patterns, and (e) human
access and
disturbance in remote areas (43, 45, 62, 132). Thus, an
evaluation of logging
regimes includes the ecological effects of both the road network
and forest spa-
tial patterns (45, 69). In conclusion, a road network disrupts
horizontal natural
processes, and by altering both landscape spatial pattern and the
processes, it
reduces biodiversity.
Road Density
Road density, e.g. measured as km/km2, has been proposed as a
useful, broad in-
81. dex of several ecological effects of roads in a landscape (39, 43,
44, 95). Effects
are evident for faunal movement, population fragmentation,
human access,
hydrology, aquatic ecosystems, and fire patterns.

ROADS AND ECOLOGICAL EFFECTS 223
A road density of approx. 0.6 km/km2 (1.0 mi/mi2) appears to
be the maxi-
mum for a naturally functioning landscape containing sustained
populations of
large predators, such as wolves and mountain lions (Felis
concolor) (43, 76, 124).
Moose (Alces), bear (Ursus) (brown, black, and grizzly), and
certain other pop-
ulations also decrease with increasing road density (11, 43, 72).
These species
are differentially sensitive to the roadkill, road-avoidance, and
human-access
dimensions of road density. Species that move along, rather
than across, roads
presumably are benefitted by higher road density (12, 39).
Human access and disturbance effects on remote areas tend to
increase with
higher road density (39, 72, 76). Similarly, human-caused fire
ignitions and
suppressions may increase, and average fire sizes decrease
(111).
85. Aquatic ecosystems are also affected by road density.
Hydrologic effects,
such as altered groundwater conditions and impeded drainage
upslope, are
sensitive to road density (116, 118). Increased peak flows in
streams may be
evident at road densities of 2–3 km/km2 (62). Detrimental
effects on aquatic
ecosystems, based on macro-invertebrate diversity, were evident
where roads
covered 5% or more of a watershed in California (75). In
southeastern Ontario,
the species richness of wetland plants, amphibians/reptiles, and
birds each
correlated negatively with road density within 1–2 km of a
wetland (38).
Road density is an overall index that averages patterns over an
area. Its
effects probably are sensitive to road width or type, traffic
density, network
connectivity, and the frequency of spur roads into remote areas.
Thus network
structure, or an index of variance in mesh size, is also important
in understanding
the effect of road density (39, 76, 79, 96). Indeed, although road
density is a
useful overall index, the presence of a few large areas of low
road density may
be the best indicator of suitable habitat for large vertebrates and
other major
ecological values.
TRANSPORTATION POLICY AND PLANNING
86. Environmental Policy Dimensions
Ecological principles are increasingly important in
environmental transporta-
tion policy, and Australia, The Netherlands, and the United
States highlight
contrasting approaches. Australian policy has focused on
biodiversity, includ-
ing wildflower protection. An enormous network of road
reserves with natural-
vegetation strips 10–200 m wide (Figure 1) stands out in many
agricultural land-
scapes (66, 92, 111). Public pressure helped create this system,
which “helps
to prevent soil erosion” and “where wildflowers can grow and
flourish in
perpetuity” (111). Diverse experimental management
approaches involve burn-
ing, weed control, planting native species, and nature
restoration. Ecological

scientists commonly work side by side with civil engineers in
transportation
departments at all levels of government.
In contrast, Dutch policy has focused on the open roadside
vegetation, road-
kills, animal movement patterns, and nature restoration (1, 21,
29, 86). This
90. approach reflects the stated national objectives of (a) recreating
“nature, in-
cluding natural processes and biodiversity; and (b) enhancing
the national eco-
logical network,” mainly composed of large natural-vegetation
patches and
major wildlife and water corridors (1, 46). An impressive series
of mitigation
overpasses, tunnels, and culverts provide for animal and water
movement where
interrupted by road barriers (24, 43, 44, 86). Environmental
activities in trans-
portation revolve around a group of environmental scientists in
the national
Ministry of Transport who work closely with engineers and
policy-makers at
both local and national levels.
In the United States, environmental transportation policy
focuses on vehic-
ular pollutants, as well as engineering solutions for soil erosion
and sedimen-
tation (85). A few states have built wildlife underpasses and
overpasses to
address local roadkill or wildlife movement concerns. A 1991
federal law—the
Intermodal Surface Transportation Efficiency Act (ISTEA)—
establishes policy
for a transportation system that is “economically efficient and
environmentally
sound,” considers the “external benefits of reduced air
pollution, reduced traffic
congestion and other aspects of the quality of life,” considers
transportation
in a region-wide metropolitan area, and links ecological
attributes with the
91. aesthetics of a landscape (43). Thus, US transportation policy
largely ignores
biodiversity loss, habitat fragmentation, disruption of horizontal
natural pro-
cesses, natural stream and wetland hydrology, streamwater
chemistry, and re-
duction of fish populations, a range of ecological issues
highlighted in the
transportation community in 1997 (85).
Of course, many nations use ecological principles in designing
transporta-
tion systems (21, 33, 63, 95, 134), and environmental scientists,
engineers, and
policy-makers in Europe have united to “conserve biodiversity
and reduce
. . .fauna casualties” at the international level (21; H van
Bohemen, personal
communication). The successful removal of lead from petroleum
led to less
lead in roadside ecosystems worldwide. Nevertheless, the huge
Australian road-
reserve system and the Dutch mitigation system for animal and
water flows are
especially ambitious and pioneering.
Spatial Planning and Mitigation
Most existing roads were built before the explosion in
ecological knowledge,
and many are poorly located ecologically (43). Yet the Dutch
have developed
a promising transportation planning process for the movement
of both people
and natural processes across the land (40, 44, 86). In essence,
the ecological
network, consisting of large natural-vegetation patches plus
95. P1: APR/ary P2: APR/ary QC: APR

ROADS AND ECOLOGICAL EFFECTS 225
water and wildlife movement, is mapped. The road network is
then superim-
posed on the ecological network to identify bottlenecks. Finally,
mitigation
or compensation techniques are applied to eliminate designated
percentages of
bottlenecks in a time sequence. The earlier such spatial
planning begins, the
greater its effect (41).
Compensation is proposed where bottlenecks apparently cannot
be over-
come by mitigation. The principle of no-net-loss has been used
internationally
for wetlands with varying success (46, 94), whereas no-net-loss
of natural pro-
cesses and biodiversity by roads is a concept only beginning to
be applied
(1, 24, 46, 86). The loss, e.g. of biodiversity or groundwater
flow, is compen-
sated by increasing an equivalent ecological value nearby.
Options include
protection of an equivalent amount of high-quality habitat,
reestablishment of
another wildlife corridor, or creation of new habitat. Mitigation,
on the other
96. hand, attempts to minimize detrimental ecological impacts and
is illustrated by
the varied wildlife passages (tunnels, pipes, underpasses,
overpasses) operating
for animal movement (21, 86).
Diverse tunnel designs focus on small and mid-sized animals.
Amphibian
tunnels, generally 30–100 cm wide and located where roads
block movement
to breeding ponds or wetlands, are widespread in Europe and
rare in the United
States (33, 43, 67). “Ecopipes,” or badger tunnels, are pipes∼40
cm in diameter
mainly designed for movement of mid-sized mammals across
Dutch roads, and
located where water can rarely flow through (9, 44, 46, 86). In
contrast, Dutch
wildlife culverts are∼120 cm wide, with a central channel for
water flow
between two raised 40-cm-wide paths for animal movement.
“Talus tunnels”
are designed for a mid-sized mammal that lives and moves in
rock talus slopes
in Australia (74).
Wildlife underpasses, generally 8–30 m wide and at least 2.5 m
high, have
been built for large mammals in southern Florida and scattered
locations
elsewhere in the United States, Canada, and France (33, 43, 54,
63, 93, 113).
Wildlife overpasses, also designed for large mammals, range in
width up to
200 m and are scarce: approximately 6 in North America (New
Jersey, Utah,
97. Alberta, British Columbia) (33, 43; BF Leeson, personal
communication) and
17 in Europe (Germany, France, The Netherlands, Switzerland)
(44, 46, 63, 86,
134). The minimum widths for effectiveness may be 30–50 m in
the center
and 50–80 m on the ends (33, 46, 86). The two Swiss overpasses
of 140-m and
200-m width remind us that ultimately the goal should be
“landscape connec-
tors” that permit all horizontal natural processes to cross roads
(43, 44).
These mitigation structures are normally combined with fencing
and vegeta-
tion to enhance animal crossing (86). Almost all such passages
are successful
in that the target species crosses at least occasionally, and most
are used by
many other species. Florida underpasses are used by the Florida
panther (Felis
concolor coryi), nearly the whole local terrestrial fauna, and
groundwater as

well (33, 54). Underpasses and overpasses are used by almost
all large mammal
species of a region. Yet, little information exists on crossing
rates relative to
101. population sizes, movement rates away from roads, predation
rates, home range
locations, and so forth. Nevertheless, mitigation passages are
effective in per-
forating road barriers to maintain horizontal natural processes
across the land.
The Road-Effect Zone
Roads and roadsides cover 0.9% of Britain and 1.0% of the
United States,
while road reserves (Figure 1) cover 2.5% of the State of
Victoria, Australia
(12, 85, 131). Yet how much of the land is ecologically
impacted by roads with
vehicles?
The road-effect zone is the area over which significant
ecological effects
extend outward from a road and typically is many times wider
than the road
surface plus roadsides (Figure 2) (39, 95, 101, 134). The zone is
asymmetric
with convoluted boundaries, reflecting the sequence of
ecological variables,
plus unequal effect-distances due to slope, wind, and habitat
suitability on
opposite sides of a road (40, 43). Knowing the average width of
the road-effect
zone permits us to estimate the proportion of the land
ecologically affected by
roads (43). For example, based on the traffic noise effect-
distances of sensi-
tive bird species described above, road-effect zones cover∼10–
20% of The
Netherlands (101).
102. Finally, a preliminary calculation for the United States was
made based on
nine water and species variables in Massachusetts (USA), plus
evidence from
the Dutch studies (42). An estimated 15–20% of the US land
area is directly
affected ecologically by roads. These estimates reemphasize the
immensity and
pervasiveness of ecological road impacts. Moreover, they
challenge science and
society to embark on a journey of discovery and solution.

SUBJECT:
This memo is meant for introducing the feasibility report that
aims at providing a solution to the cases and nation problems
about the cybercrime and the potential proposed solution to curb
up the challenge. These feasibilities we are identified by
studying various critical factors such as the social effects, legal
issues, technical problems, and the economic impact. Therefore,
this memo is very vital for an individual to read and understand
various aspects.
Feasibility Report
It takes much time in planning and preparing to implement a
solution to the major problem in society. During the planning
and preparation process, the proposed solution should be tested
and determined if it is feasible to provide the solution or not.
Cybercrime in united states has been a significant problem and
need to be addressed and solution provided to reduce the
cybercrime.
One of the proposed solutions to this major problem is
providing cybersecurity among very individual. This will enable
most of the people to understand and know the importance of
cybersecurity and thus leading to the reduction of the negative
loses that is caused by the cybercrime in society every year.
152. Another thing that will ensure that the individuals in the nation
are protected from the impact of the cybercrime is educating
them on ways they can protect themselves over the cybercrime
attempts.
This report will majorly focus on looking at the proposed
solution provided and determine if the answers are feasible or
need some changes. The essential aspects that the story will
focus on include the social impact, the economic effect, and
other elements which will be determined if it can provide a
solution to the problem.
The Social Impact
When looking for a potential solution to be implemented to
solve a specific major problem in society, a positive impact is
always the main objective. When the proposed solution is
applied, such as implementing cybersecurity in the daily lives
of the individuals in the society it will bring a lot of positive
impacts on them. For instance, when the cybersecurity is made
the main focus in the in every place, i.e. schools and workplace,
majority of the individuals will be aware of these threats and
ways of preventing them from affecting their daily lives. This
will also reduce the loss that most of the individuals incur due
to the cybercrime and lack of security in their day-to-day
business operations (Help Net Security, 2015).
When the cybersecurity is introduced in society It will bring
much social impact to the life of the individuals since it will
educate people about the dynamic changes that occur in uses of
the technology. When this provides a solution to the cybercrime
problem in the society, it will be adopted by every nation, and
thus the cybercrime problem is reduced and making every
country secure and safe from the cybercrime problems.
Economic Effect.
One of the most critical aspects of coming up with the proposed
solution is the economic feasibility impact. The projected
resolution calls for basically a change in lifestyle in the United
States. The cybersecurity needs to be the main part of the
individuals that will make them safe and preventing the
153. occurrence of cybercrime. The cybersecurity has to be
implemented in the workplace and various institutions to
achieve the required objectives of solving the issue of
cybercrime in society.
The process of implementation has a great financial cost, but
the results brought by the proposed solution will bring much
economical cost since it will reduce the amount that could have
been used to solve the loss and cases caused by the cybercrime
in the society. When the financial loss incurred due to the
cybercrime is compared to the cost of implementing the
solution, there is a significant difference since the proposed
solution implementation saves much money.
Technical and Legal Issues
For every proposed solution, becoming successful in solving the
intended problem, there are several legal and professional issues
to be followed during the process of implementation. To
implement cybersecurity in the workplaces and the institutions,
some legal issues have to be developed for it to be successful.
Also, during the process of implementation of the
cybersecurity, the technical aspects have to be looked at. The
technical issues involve various aspects such as unforeseen
failure of the system in providing the solution for the problem.
The technical issues will also identify the bugs that will prevent
the proposed solution from providing the solution to the major
problem. The proposed solutions seem to be free from the
technical and legal issues, and thus it may provide the required
solution to the major problem of cybercrime in the United
States.
Conclusion
Generally, the proposed solution to the major problem of
Cybercrime in the United States is more feasible. The problem
in achieving the solution is the lack of financial support during
the process of implementation of the proposed solution. If the
proposed solution gets financial support, it requires, and it will
154. be easy to implement it and bring the required resolution.
However, considering all other criteria measured to determine
the feasibility of the proposed solution, I found that
implementing the solution either caused little to no impact or
had a positive effect, such as the case with Social implications.
From the above observation, if there will be no financial
distress during the implementation process, the proposed
solution will be successful in solving the major problem of
cybersecurity.

Book Title: Technical Writing for Success
Learning, Cengage LearningChapter Introduction
Goals
Explain the difference between technical reading and literary
reading
Preview and anticipate material before you read
Use strategies for reading technical passages
Terms
acronyms (letters that stand for a long or complicated term or
series of terms) annotating (handwritten notes, often placed in
the margins of a document being read) anticipate (to guess or
predict before actually reading a passage what kind of reasoning
it might present)
background knowledge (knowledge and vocabulary that a reader
has already learned and then calls upon to better understand
new information)
formal outline (a listing of main ideas and subtopics arranged in
a traditional format of Roman numerals, capital letters,
numbers, and lowercase letters)
graphic organizers (the use of circles, rectangles, and
connecting lines in notes to show the relative importance of one
piece of information to another)
informal outline (a listing of main ideas and subtopics arranged
in a less traditional format of single headings and indented
notes)
literary reading (reading literature such as short stories, essays,
poetry, and novels) pace (to read efficiently; to read at a rate
that is slow enough to allow the mind to absorb information but
fast enough to complete the reading assignment)
previewing (looking over a reading assignment before reading
it; determining the subject matter and any questions about the
material before reading it) technical reading (reading science,
business, or technology publications)
technical vocabulary (specialized words used in specific ways
unique to a particular discipline)
156. Write to Learn
How does a science or computer textbook differ from a work of
literature? Do you read scientific or technical material
differently from the way you read literature? If so, how? Do you
like to read? Why or why not? How often do you read scientific
or technical information? How do you remember what you read?
Write a journal entry addressing these questions.
Focus on Technical Reading
Read Figure 16.1 and answer these questions:
What features of technical writing do you recognize in the
passage?
What has the reader done to interact with and understand this
passage?
What kind of information has the reader noted?
What If?
How might the model change if …
The passage included more technical vocabulary?
The information in the passage was part of a presentation on
satellites?
The passage included a couple of graphics?

Stephen Freas is a construction subcontractor in Winston Salem,
North Carolina. He is a supervisor on job sites and manages
small crews to build projects based on drawings provided by the
general contractor. He writes contracts, e-mails with clients,
and often consults manuals and building codes.
157. The contracts Stephen writes are more than just fine print to be
skimmed and signed. “A contract lets the client know exactly
what we’re going to do—what materials and processes will be
necessary, what those will cost, and what the potential risks
are,” says Stephen. “A detailed contract also prevents us from
doing costly work for free.”
Stephen’s job requires him to do a great deal of technical
reading. “Reading construction plans and technical manuals
requires a physical engagement with the writing,” he says. “In
these texts, an action usually follows each sentence or image.
This makes for slow but ‘action-packed’ reading that helps you
accomplish something you had no idea how to do previously.”
Stephen often combines information gleaned from several
different pieces of technical writing in order to make proper
decisions. For example, “Once, we built a handicap ramp to the
specifications written by the contractor. Upon inspection, the
city told us that the ramp did not meet its building code
standards. I refused to rebuild the ramp until I read the city
code myself. The code listed specifics such as ramp thickness;
railing height; and, most important, ramp slope. I calculated
that in order to meet city code specifications, the ramp needed
to be three times longer than the contractor’s original plan and,
coincidentally, the same slope as the existing sidewalk.”
Stephen credits his technical reading dexterity to countless
hours of following instruction manuals for his car, photography,
climbing, and other hobbies.
Think Critically
1. Why does Stephen consider construction plans and technical
manuals to be “action-packed”?
2. Think about the completed handicap ramp from the point of
view of Stephen, the general contractor, and the building
inspector. What solution would work for everyone?
