Western Corn Belt Plains
The Western Corn Belt Plains is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in seven U.S. states, though predominantly in Iowa. It has been subdivided into fifteen Level IV ecoregions. Description Once covered with tallgrass prairie, over 75 percent of the Western Corn Belt Plains is now used for cropland agriculture and much of the remainder is in forage for livestock. A combination of nearly level to gently rolling glaciated till plains and hilly loess plains, average annual precipitation of 26–37 inches, which occurs mainly in the growing season, and fertile, warm, moist soils make this one of the most productive areas of corn and soybeans in the world. Major environmental concerns in the region include surface and groundwater contamination from fertilizer and pesticide applications as well as impacts from concentrated livestock production.

List Of Ecoregions In North America (CEC)
This list of ecoregions of North America provides an overview of North American ecoregions designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. It should not be confused with Wikipedia articles based on the classification system developed by the World Wildlife Fund, such as List of ecoregions (WWF) and Lists of ecoregions by country. The commission was established in 1994 by the member states of Canada, Mexico, and the United States to address regional environmental concerns under the North American Agreement on Environmental Cooperation (NAAEC), the environmental side accord to the North American Free Trade Agreement (NAFTA). The commission's 1997 report, ''Ecological Regions of North America'', provides a framework that may be used by government agencies, non-governmental organizations, and academic researchers as a basis for risk analysis, resource management, and environmental study of the continent's ecosystems.

Ecoregions Of Kansas
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Ecoregions In The United States (WWF)
The following is a list of ecoregions in the United States as identified by the World Wide Fund for Nature (WWF). The United States is a megadiverse country with a high level of endemism across a wide variety of ecosystems. Terrestrial ecoregions The United States is unique among countries in that its terrestrial ecoregions span three biogeographic realms: the Nearctic, Neotropical, and Oceanian realms. 50 states Alaska is the most biodiverse state with 15 ecoregions across 3 biomes in the same realm. California comes in a close second with 13 ecoregions across 4 biomes in the same realm. By contrast, Rhode Island is the least biodiverse with just one ecoregion - the Northeastern coastal forests - encompassing the entire state. The terrestrial ecoregions of the 50 states of the United States are as follows: 5 inhabited territories The ecoregions of the 5 inhabited territories of the United States are as follows: Marine ecoregions The marine ecoregions of the 50 states of ...

World Wildlife Fund
The World Wide Fund for Nature Inc. (WWF) is an international non-governmental organization founded in 1961 that works in the field of wilderness preservation and the reduction of human impact on the environment. It was formerly named the World Wildlife Fund, which remains its official name in Canada and the United States. WWF is the world's largest conservation organization, with over five million supporters worldwide, working in more than 100 countries and supporting around 3,000 conservation and environmental projects. They have invested over $1 billion in more than 12,000 conservation initiatives since 1995. WWF is a foundation with 65% of funding from individuals and bequests, 17% from government sources (such as the World Bank, DFID, and USAID) and 8% from corporations in 2020. WWF aims to "stop the degradation of the planet's natural environment and to build a future in which humans live in harmony with nature." The Living Planet Report has been published every two y ...

List Of Ecoregions In Wisconsin
The list of ecoregions in Wisconsin are listings of terrestrial ecoregions (see also, ecosystem) in the United States' State of Wisconsin, as defined separately by the United States Environmental Protection Agency (USEPA), and the World Wildlife Fund. USEPA The USEPA ecoregion classification system has four levels, but only Levels I, III, and IV are shown on this list. Level I divides North America into 15 broad ecoregions (or biomes). Wisconsin is within the Eastern Temperate Forest, and in the Great Plains, Level I regions. Level IV ecoregions (denoted by numbers and letters) are a further subdivision of Level III ecoregions (denoted by numbers alone). tp://ftp.epa.gov/wed/ecoregions/wi/wi_eco.pdf Level 3 and Level 4 Ecoregions of WisconsinUSEPA Great Plains * 47 Western Corn Belt Plains **47g - Prairie Pothole Region Eastern Temperate Forest *50 Northern Lakes and Forests **50a - Lake Superior Clay Plain **50b - Minnesota/Wisconsin Upland Till Plain **50c - St. Croix Pine ...
