Ecoregions of North America, featuring the 50 United States, the District of Columbia and the five inhabited territories. 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.
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. [1] In the United States, the EPA and the United ...
A number of organizations such as the United States Nature Conservancy and the World Wildlife Fund have begun working together to conserve the threatened desert ecosystem. The less heavily populated areas of the desert are being sought out and conserved in order to prevent future human habitation and disturbance. [ 15 ]
Terrestrial ecoregions of the world. This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial, freshwater, and marine ecoregions.
A map of the Amazon rainforest ecoregions. The yellow line encloses the ecoregions per the World Wide Fund for Nature. A map of the bioregions of Canada and the US. An ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm.
A team of biologists convened by the World Wildlife Fund (WWF) developed a scheme that divided the world's land area into biogeographic realms (called "ecozones" in a BBC scheme), and these into ecoregions (Olson & Dinerstein, 1998, etc.). Each ecoregion is characterized by a main biome (also called major habitat type).
The Everglades are the largest tropical wilderness in the United States. This mangrove and tropical rainforest ecosystem and marine estuary is home to 36 protected species, including the Florida panther, American crocodile, and West Indian manatee. Some areas have been drained and developed; restoration projects aim to restore the ecology. [43]
A country that consumes more than 1.73 gha per person has a resource demand that is not sustainable world-wide if every country were to exceed that consumption level simultaneously. Countries with a footprint below 1.73 gha per person might not be sustainable: the quality of the footprint may still lead to net long-term ecological destruction.
