What is the cause and the effect of urban sprawl?
What are the causes and consequences of urban sprawl? Although some would argue that urban sprawl has its benefits, such as creating local economic growth, urban sprawl has many negative consequences for residents and the environment, such as higher water and air pollution, increased traffic fatalities and jams, loss of agricultural capacity, increased car dependency,
How does urban sprawl impact biodiversity?
Urbanization impacts biodiversity and ecosystem services both directly and indirectly. Direct impacts primarily consist of habitat loss and degradation, altered disturbance regimes, modified soils and other physical transformations caused by the expansion of urban areas.
How does urban sprawl affect nature?
Urban sprawl can reduce water quality by increasing the amount of surface runoff, which channels oil and other pollutants into streams and rivers. Poor water quality is associated with a variety of negative health outcomes, including diseases of the gastrointestinal tract, kidney disease, and cancer.
How can we protect wildlife from urban sprawl?
Human-created habitats can also provide significant habitat for wildlife in urban areas. For example, green infrastructure strategies, such as protecting riparian corridors and floodplains, building green roofs, and establishing urban tree canopy, provide environmental and community benefits.
How does urbanization affect natural habitats?
Urbanisation leads to habitat fragmentation, where larger continuous habitats are divided into smaller unconnected patches. It also causes habitat loss, through an increase in roads and buildings that are not producing any biomass. This exposes wildlife to new man-made stress.
How does urban sprawl negatively affect the environment?
Urban sprawl has significant environmental, economic and social consequences. It leads to higher emissions from road transport and loss of open space and environmental amenities. It also increases the cost of providing key public services, exerting pressure on local public finance.
What are the negative impacts of urban sprawl?
Urban sprawl has many negative consequences for residents and the environment, water and air pollution, increased traffic and traffic jams, increased car dependency, parking, etc.).
How does urbanization affect vegetation?
The impacts of urbanization on vegetation growth can be decomposed into direct and indirect effects (11). The direct effect is generally negative and refers to the transformation of land cover from natural surfaces to impervious ones, reducing vegetation cover and growth (12, 13).
How do you attract urban wildlife?
A basic tenet of attracting wildlife is diversity. Maximize the number of plant species in your yard. Favor a mixture of plants with varying timing of blooms and fruit, height and structure. Intersperse wildlife-friendly trees with other habitat components like shrubs, wildflowers, vines and water sources.
How has Urbanisation affected animal Behaviour?
We confirmed the thesis that urbanization affects the social behavior and urban and rural populations differ from each other. Urban animals are less likely to avoid close contact with each other and are more likely to show tolerant behavior. They also have a lower tendency towards monopolization of food resources.
How is urbanization a threat to biodiversity?
Urbanisation has an important impact on biodiversity, mostly driving changes in species assemblages, through the replacement of specialist with generalist species, thus leading to biotic homogenisation. Mobility is also assumed to greatly affect species' ability to cope in urban environments.
How urbanization causes increase of invasive species?
Urbanization increases the number and extent of non-native invasive species by increasing the rate of introduction events and creating areas of disturbed habitat for non-native species to become established (e.g., McDonald and Urban 2006).
How does urban development affect the environment?
Urban development can magnify the risk of environmental hazards such as flash flooding. Pollution and physical barriers to root growth promote loss of urban tree cover. Animal populations are inhibited by toxic substances, vehicles, and the loss of habitat and food sources.
How does urban sprawl affect climate change?
These impacts threaten both the natural and rural environments, raising greenhouse gas emissions that cause climate change, and elevated air and noise pollution levels which often exceed the agreed human safety limits. Thus, urban sprawl produces many adverse impacts that have direct effects on the quality of life.
What are three environmental negative effects of urban sprawl quizlet?
The environmental impacts of urban sprawl include: a depletion of natural resources, air pollution, water pollution and loss, loss of agricultural land, and a loss of habitat and biodiversity.
How does urban sprawl cause land degradation?
Urban sprawl leads to horizontal rather than vertical growth, demanding a large proportion of natural resources at the expense of farming and forest areas, semi-natural environments, and wetlands, and making landscapes more vulnerable to degradation in long-term through various disturbances such as biodiversity loss.
How many species of plants and animals will be extinct in the next 25 years?
Urban sprawl is gobbling up open spaces in fast-growing metropolitan areas so quickly that it could spell extinction for nearly 1,200 species of plants and animals, environmental groups say. The National Wildlife Federation, Smart Growth America and NatureServe projected that over the next 25 years, more than 22,000 acres ...
Which county has the most endangered species?
California has 16 of the 20 counties the groups said have the most imperiled species, led by San Diego, Los Angeles, San Bernardino and Sonoma counties. Other counties with the most imperiled species are Clark in Nevada; Miami-Dade in Florida; and Bibb and Shelby in Alabama.
What is urban sprawl?
-Urban sprawl gives larger area for people to build houses and buildings. People with larger families can build out in the suburbs and not have to live in houses that are too small.
Why are forests, wetlands, meadows and valleys cut, bulldozed and paved?
Forests, wetlands, meadows and valleys are cut, bulldozed and paved over to make room for urban expansion. -Farmland is destroyed, causing food not to be able to grow near cities. -New roads and sidewalks slice through natural habitats, threatening many different species of wildlife.
Answer
Urban sprawl is the spreading of urban areas into the countryside. It is not only spread to the rural areas but also towards the wildlife habitats. The cause of urban sprawl is the lack of space in towns and cities and an increasing population.

What animals are displaced by development?
White-tailed deer may be the most visible of our native animals displaced by development. The need for herd reduction on National Park Service lands demonstrates just one of many challenges in managing the deer population in developed areas. Regardless of your position on this controversial issue, the fact remains that deer have done their best to adapt to their changing environment and we may need to adapt as well.
What can local residents do to help wildlife?
Local residents concerned with urban sprawl and effects on wildlife can partner with the National Wildlife Federation to create a certified safe haven for native birds and animals on privately owned acreage. Concerned residents can contact legislators to encourage smart growth in communities.
What are some examples of wildlife habitats?
A few examples are the Florida panther, black-tailed prairie dog and Pacific salmon.
How do national organizations manage land use?
Numerous national organizations focus on managing land use in the United States in a manner that balances growth and development with a need to preserve open space. By creating reserves for wildlife management and protecting watersheds that preserve freshwater ecosystems, these organizations promote a balanced approach to development.
Do black bears migrate?
However, population growth has had an effect on the migration patterns of the black bear as evidenced by several recent stories of bear sightings in South Central Pennsylvania documented in area newspapers. Ultimately, bears that move from bird feeder to garbage can as primary food sources become a nuisance to homeowners. In rare cases the black bear may endanger residents, most often as a traffic hazard. We all benefit by keeping the black bear in remote areas of the state where foraging for bugs and berries as nature intended keeps them safe, healthy and out of trouble in the human domain.
Do plants deter deer?
For home gardeners with small planting spaces, choosing particular plants that deter deer, will allow for a nice landscape in spite of roaming deer populations. It is important to note that these plants are only deer resistant, not necessarily deer proof. A combination of aromatic plants and those that are less than tasty will deter deer from making a meal of your landscape. Using a combination of these plants in a ratio of 2-to-1 with other plants allows the home gardener to camouflage those that are neither aromatic nor bitter.
How will suburban development affect the environment?
As suburban development continues to sprawl outward, habitat loss and degradation are also likely to accelerate. This report estimates the pace of land consumption in the country’s fastest growing large metro areas over the next 25 years, and investigates what those metropolitan areas are doing to protect their natural lands from overdevelopment. In this report, we sometimes refer to natural lands as “green infrastructure” because it carries the implicit message that these open spaces are necessities that play important functional roles (e.g. filtration of water, wildlife habitat, etc.,) and thus are deserving of serious public planning and investment.
Why should disappearing species and habitats concern everyday citizens?
hy should disappearing species and habitats concern everyday citizens? Because they literally cannot live without them . Composed of thousands of different species, forests, wetlands, grasslands and other natural habitats purify drinking water, recharge aquifers, help prevent droughts, protect against floods, and help maintain a stable climate. Each time a species is removed from a natural system, many other species in that system can be affected. This can lead to unpredictable chain reactions that can harm human health and economic viability. To take just one example, pollinators such as bees generate enormous economic benefits, even as their numbers decline. Over 90 percent of all flowering plants and over 75 percent of the staple crop plants that feed humankind rely on pollinators.14
What threatens the survival of nearly one out of every three imperiled species in the U.S.?
Rapid consumption of landcould threaten the survival of nearly one out of every three imperiled species in the U.S....Runaway development threatens the very survival of these national treasures and underscores the urgency for comprehensive habitat protection strategies and planning for green infrastructure.
What does it mean to be smart about growth?
Being smart about growth means revitalizing existing cities and suburbs and making efficient use of land, rather than building in outlying farm fields and forests. It means making cities and suburbs affordable places to live, so that everyone can participate in and benefit from this revitalization.
How much land will be lost to development in the next 25 years?
In total, roughly 22,374 square miles (an area the size of West Virginia) of natural resource and habitat land in these 35 metro areas are projected to be lost to development over the next 25 years. This runaway land consumption can only be reduced if development is channeled into existing urban and suburban areas, new development is built to be more compact, and natural areas are protected from irresponsible development.
Why is proximity to natural areas important?
Proximity to natural areas has also been linked to improved health and increased property values. According to a recent study, people living near parks and other natural areas live healthier lives with fewer hospital visits.24In a recent poll, the National Association of Realtors found that 57 percent of voters would be more likely to purchase a home close to green space, and fifty percent said they would be willing to pay ten percent more for a home located near a park or other protected natural area.25
Why is it important to protect natural areas from overdevelopment?
Beyond safeguarding individual species, protecting natural areas from overdevelopment can generate major economic and environmental benefits, particularly with regard to protecting wate.…Land conservation can help reduce the impacts of polluted runoff, which threatens both drinking water quality and the survival of aquatic habitats across the U.S.
How does urbanization affect bird communities?
Many investigators found that urbanization decreased the species diversity of the avian community and increased avian density (or bird biomass), favoring dominance by a few species. Bird species vary in sensitivity to urbanization, leading to loss of sensitive species and a shift in the species composition of urban versus forest bird communities. Habitat specialists, including many forest insectivores, neotropical migrants, and forest interior species, have been documented to be less tolerant of urbanization. Beissinger and Osborne (1982), Smith and Schaefer (1992), Franklin and Wilkinson (1996), Kluza and others (2000), Croonquist and Brooks (1993), and Dowd (1992) all documented shifts in avian species composition with increasing urbanization.
How does fragmented forest affect wildlife?
Fragmented forests have a greater proportion of edge habitats. Edges have generally been regarded by wildlife managers to have a positive effect on wildlife because the number of species increases near habitat edges (Yahner 1988). This positive effect likely remains true for birds in predominantly forested landscapes. In fragmented landscapes, however, maximizing species diversity is not always a desirable objective in light of the number of rare species that depend on large areas of habitat. Rates of nest predation and brood parasitism are greater at edges for some forest nesting birds (Gates and Gysel 1978), especially as overall forest cover becomes increasingly fragmented (Donovan and others 1997). Paton (1994) reviewed a number of studies that dealt with bird nesting success as a function of distance from an edge. Most studies found that nesting success decreased near edges as a result of increasing nest predation and parasitism rates. The strongest effects appeared to occur within about 125 feet of the edge. Indigo bunting nests along abrupt forest edges, such as agricultural edges, wildlife openings or campgrounds, had nearly twice the nest predation rate as those found along more gradual edges, such as those created by treefalls, streamsides, and gaps created by selective logging (Suarez and others 1997).
Why are nesting birds less successful in small forest?
Reduced reproductive success of forest nesting birds in small or fragmented forests may be due to increased nest predation or nest parasitism by brown-headed cowbirds. Nest parasitism is associated with brown-headed cowbirds, which lay their eggs in the nests of other species. These hosts then raise cowbirds at the expense of their own offspring. Nest predation can be caused by a combination of many avian, mammalian, and reptile species. Rates of nest predation have been found to be higher in small forest tracts than in large forest tracts, and small urban forest tracts experience higher rates of predation than comparably sized forest tracts in isolated rural areas (Wilcove 1985). Migratory songbird populations suffer the most serious effects from increased predation in small forest tracts. Keyser and others (1998), Donovan and others (1995), Robinson (1992), and Robinson and others (1995) all documented reduced reproductive success of neotropical migrants and other forest nesting bird species in fragmented forests due to higher rates of nest predation and/or nest parasitism.
What is the importance of forest cover?
Recently, investigators stress the importance of overall forest cover or landscape levels of fragmentation surrounding a local area when evaluating the presence or nesting success of area-sensitive or forest-interior birds. As indicated by Villard (1998), preference for forest-interior habitat or avoidance of small fragments tends to focus attention on the local scale, whereas processes underlying these phenomena may take place over landscape or even continental scales. Therefore, forest-interior preference and area sensitivity should be considered in a landscape context. In one study, forest cover in approximately 40-square-mile study plots was found to be the most important factor affecting the distribution of forest birds (Trzcinski and others 1999). Comparatively, the independent measures of forest fragmentation produced effects that were inconsistent and far less important than overall forest cover. In addition, the reduction in nesting success of forest birds due to nest predation and parasitism was much greater in heavily fragmented landscapes with low forest cover than in heavily forested landscapes (Hartley and Hunter 1998, Robinson and others 1995). Similarly, no differences were detected in the breeding success of worm-eating warblers in small and large forest tracts when high amounts of forest canopy cover were present in the surrounding landscape (Gale and others 1997).
Why are corridors important?
The presence of connective corridors may help to reduce the isolation of wildlife populations in fragmented forests (MacClintock and others 1977, Machtans and others 1996, Wegner and Merriam 1979). Corridors may provide a connection that allows wildlife to move from one patch to another across an intervening, inhospitable landscape. This phenomenon has been especially well documented for disturbance-dependent grassland and scrub-shrub bird species, such as Bachman’s sparrow in largely forested areas (Dunning and others 1995). It is not obvious that animals possessing the mobility of birds need corridors to cross-fragmented landscapes, but it appears that the open space between forest islands is a barrier to movement of some songbirds (Whitcomb and others 1981). Gaps of 250 feet or more produced isolation characteristics for some songbirds in small forest fragments created by power lines and roads (Robbins and others 1989). Such gaps may not represent as serious a problem in largely forested landscapes, however (Gale and others 1997). Some investigators question the conservation value of corridors or question whether sufficient experimental evidence exists to draw conclusions on their benefits (Inglis and Underwood 1992, Simberloff and others 1992). Several potential negative effects and disadvantages of corridors should be considered prior to their use in overcoming fragmentation (Simberloff and others 1992). Disagreement over the value of corridors to overcome the effects of fragmentation for various species is likely to continue for some time. The use of corridors and the effect of fragmentation on movement patterns seem to be highly species-specific (Debinski and Holt 2000).
What are some of the most important documents that documented the loss of sensitive forest bird species after urbanization?
Butcher and others (1981), Askins and Philbrick (1987), Aldrich and Coffin (1980), Long and Long (1992), and Horn (1985) documented the loss of sensitive forest bird species after urbanization or their return after reforestation.
Why do Cooper's Hawks abandon their nests?
Cooper’s hawks abandon nest sites when housing construction and residential disturbance encroach on established nest sites (Bosakowski and others 1993).
How does urbanization affect wildlife?
While the impact of urbanisation does hit those species that were meant to live in a non-urban habitat, protecting urban biodiversity may be a viable strategy to benefit wildlife. When conditions in natural habitats can become truly hostile, urban environments may be a more welcoming place to be. Cities are certainly no reserves, but animals do enjoy a higher survival rate.
How does urban wildlife contribute to ecosystem services?
Urban wildlife significantly contributes to ecosystem services in urban areas, where ecosystem services are usually understood as the benefits provided by ecosystems that contribute to making human life possible and worth living.
Why is it important to encourage biodiversity in urban ecosystems?
Population growth and urbanisation are chipping away at natural spaces, but it is paramount for our health to encourage biodiversity in urban ecosystems and focus our attention on urban ecology. The greener the city, the better, but this is not enough. Governments’ policies should channel their efforts into the creation of suitable habitats for urban wildlife.
Why are cities important to wildlife?
Although the controversies about urban beekeeping are casting some doubts over the actual viability of urban biodiversity protection strategies , cities may actually turn out to be a valuable aid to wildlife population. The combination of natural and human-made food provides them with abundant supply of food, enough to eliminate competition in search for provisions. Brownfield sites, meadows and parks can become an oasis for wildlife: animals can also have access to blooming gardens all year round and they can enjoy a less rigid climate.
What are the factors that attract animals to human settlements?
While not all urban areas can cater to the needs of the urban animal populations, cities can become a wildlife refuge. Food, water, shelter and suitable habitat are the key factors that attract animals to human settlements.
What is urban wildlife?
Urban wildlife is a term coined exactly to identify wildlife that lives in urban environments. Some simply cohabit with humans, others depend on human activities for their survivals in the cities. Taxonomic requirements often classify urban wildlife as ‘exploiters’, ‘adapters’ or ‘avoiders’, but whether or not it is possible to adopt such sharp categorization, both animal welfare and concern for ecological impact call for new policies to regulate urban wildlife conservation.
Why do animals get stuck in jars?
Some animals get stuck in discarded jars when they look for food. Generally speaking, animals can mistake trash for food and even when they do find food, wildlife still does best on natural provisions. Conflicts between wildlife and domestic animals are an additional bone of contention among wildlife conservationists.
