Sprawl – Wetlands Add-On

Urban sprawl kills wetlands


EPA, 2003 - Environmental Protection Agency (EPA, “Urban Sprawl,” PolicyAlmanac, 2003, http://www.policyalmanac.org/environment/archive/urban_sprawl.shtml ) //AX

“ Population growth is the most significant factor effecting urban sprawl in the Mid-Atlantic region. As population size increases, so does the amount of land required for residential and commercial needs. In the Chesapeake Basin alone, between the years of 1950-1980, the percent of land used for residential and commercial purposes increased nearly 180% while population increased about 50%. Based upon current trends in Maryland, in a recent six-month period, approximately 5,000 people left Baltimore City; 3,000 septic permits were issued; and nearly 10,000 acres of forests and farmlands were lost. If these trends continue, Maryland could use as much land for development in the next 25 years as it has used in the entire history of the state. Likewise, in Northern Virginia, development is expanding beyond the current service areas of public water supplies provided by the Potomac River. Specifically, Northern Virginia's Loudoun County's population has increased by nearly 150 percent from 57,000 in 1980 to nearly 140,000 today, with the landscape changing from rural to suburban. Ground water is being utilized to support the uncontrolled growth. Yet, no assessment has been conducted on groundwater availability and how aquifers are being impacted by suburban sprawl. In its path, sprawl consumes thousands of acres of forests and farmland, woodlands and wetlands. It requires government to spend millions extra to build new schools, streets and water and sewer lines. In its wake, sprawl leaves boarded up houses, vacant storefronts, closed businesses, abandoned and often contaminated industrial sites, and traffic congestion stretching miles from urban centers. There are over 700,000 kilometers of roads connecting urban areas within the Mid-Atlantic region! As a result, we suffer from increased traffic congestion, longer commutes, increased dependence on fossil fuels, crowded schools, worsening air and water pollution, threatened surface and ground water supplies, lost open space and wetlands, increased flooding, destroyed wildlife habitat, higher taxes, and dying city centers.”


Wetlands are key to the hydro-cycle – the impact is extinction


Ramsar Convention, 96, “Ramsar Convention on Wetlands, Wetlands and Biodiversity, Executive Summary”, http://www.ramsar.org/about/about_biodiversity.htm, ACC: 12.20.08, p. online

Wetlands - including (inter alia) rivers, lakes, marshes, estuaries, lagoons, mangroves, seagrass beds, and peatlands - are among the most precious natural resources on Earth. These highly varied ecosystems are natural areas where water accumulates for at least part of the year. Driven by the hydrological cycle, water is continuously being recycled through the land, sea and atmosphere in a process which ensures the maintenance of ecological functions. Wetlands support high levels of biological diversity: they are, after tropical rainforests, amongst the richest ecosystems on this planet, providing essential life support for much of humanity, as well as for other species. Coastal wetlands, which may include estuaries, seagrass beds and mangroves, are among the most productive, while coral reefs contain some of the highest known levels of biodiversity (nearly one-third of all known fish species live on coral reefs). Other wetlands also offer sanctuary to a wide variety of plants, invertebrates, fishes, amphibians, reptiles and mammals, as well as to millions of both migratory and sedentary waterbirds. Wetlands are not only sites of exceptional biodiversity, they are also of enormous social and economic value, in both traditional and contemporary societies. Since ancient times, people have lived along water courses, benefiting from the wide range of goods and services available from wetlands. The development of many of the great civilisations was largely based on their access to, and management of, wetland resources. Wetlands are an integral part of the hydrological cycle, playing a key role in the provision and maintenance of water quality and quantity as the basis of all life on earth. They are often interconnected with other wetlands, and they frequently constitute rich and diverse transition zones between aquatic ecosystems and terrestrial ecosystems such as forests and grasslands.

Urban sprawl devastates key forest habitats like wetlands

“Land Use & Urban Sprawl Land use and urban sprawl are major environmental concerns affecting us in a variety of ways. We must adopt sustainable patterns of development which are not self-destructive. What is Urban Sprawl? "Sprawl" is the increased use of urbanized land by fewer people than in the past. Traditional cities were compact and efficient, but over the past 30-50 years, the density of land used per person has declined drastically. Although the U.S. population grew by 17 percent from 1982 to 1997, urbanized land increased by 47 percent during the same 15 year period. The developed acreage per person has nearly doubled in the past 20 years, and housing lots larger than 10 acres have accounted for 55 percent of land developed since 1994, according to the American Farmland Trust. Land use and urban sprawl are major environmental concerns affecting us in a variety of ways. We must adopt sustainable patterns of development which are not self-destructive. Impacts of Sprawl Land Use and Urban Sprawl Between 1950 and 2002, the number of acres of farmland in Wisconsin dropped by 32.6%, from 23.6 million acres down to 15.9 million. 1. Loss of Farmland --- We're chewing up farms at an alarming rate across the U.S., to create new highways, fringe industrial parks and sprawled housing developments. This loss reduces our ability to grow food, fiber and timber. In many areas, urban development pressure and increased property taxes are forcing farmers out of business. They often sell their farms for housing developments, to provide financial security for their retirement. * Wisconsin Farms - In 1950, Wisconsin had 23.6 million acres of farmland, but 32.6% of this farmland has disappeared, leaving us with only 15.9 million acres in 2002, according to the Wisconsin Agricultural Statistics Service. The number of Wisconsin farms has dropped from 178,000 down to 77,000, from 1910 to 2002. [Some of this farm loss is due to consolidation into much larger farms. * Nationwide - More than 13.7 million acres of farmland in the U.S. were converted to non-farm use just between 1992 and 1997, according to United States Department of Agriculture. This figure is 51% higher than between 1982 and 1992. 2. Loss of Wildlife Habitat --- Wild forests, meadows, and wetlands are also disappearing, replaced by pavement, buildings and sterile urban landscaping. [See Wildlife] The remaining habitat is smaller, degraded and more fragmented, making survival of certain wildlife species very difficult as they try to reach breeding ponds, hibernation sites, feeding locations, or to establish viable nesting areas. According to the Wisconsin Department of Natural Resources, important habitat types are disappearing. For example: * Grasslands - Wisconsin has only .5% (13,000 acres) of its original grassland ecosystem remaining in a relatively intact condition, but much of this remnant acreage has been degraded to some degree * Oak Savannas - Intact examples of oak savanna vegetation are now so rare that less than 500 acres are listed in the Natural Heritage Inventory as having a plant assemblage similar to the original oak savanna. This is less than 0.01% of the original 5.5 million acres. * Oak and Pine Barrens - Less than 1% of the pre-settlement oak and pine barren habitat remains * Shorelands - Degradation of near-shore and shoreline wildlife habitat is increasing with the pace of development, particularly in northern Wisconsin where, since 1960, two thirds of the larger lakes have been developed, the number of home sites has doubled, and the annual number of permits for sea wall construction has tripled. The DNR now reviews and processes over 10,000 permits for piers, near shore ponds, and structures each year. * Wetlands - More than 50% of Wisconsin's original wetlands have been lost. On the lower Bay of Green Bay, more than 90% of the wetlands are gone.”
