Description:
The ecoregions of Wyoming have been identified, mapped, and described and provide a geographic structure for environmental resources research, assessment, monitoring, and management. This project is part of a larger effort by the U.S. EPA to create a national, hierarchical ecoregion framework. This ecoregion framework is methodologically consistent with those developed elsewhere by the U.S. EPA and allows biologists and resource managers to share and compare environmental data across political boundaries. The amount of environmental detail that is delineated at different hierarchical levels varies from level I, the broadest grouping, to level IV, the most detailed.
The Wyoming project refined and subdivided the level III ecological regions of Wyoming. It involved researchers from U.S. EPA National Health and Environmental Effects Research Laboratory - Corvallis, U.S. EPA Region VII, U.S. Department of Agriculture - Natural Resources Conservation Service, U.S. Department of the Interior - Bureau of Land Management, Wyoming Department of Environmental Quality, and U.S. Department of the Interior - Geological Survey - Earth Resources Observation Systems Data Center. The refined Wyoming ecoregions will be published as a double-sided, color poster by the U.S. Geological Survey (USGS) and will measure 34 x 44 inches. The poster includes an original 1:1,400,000 scale map that delineates the seven level III and thirty-nine level IV ecoregions of Wyoming. Each ecoregion is described in the accompanying text and tables. 14 other posters in the ecoregion series have already been published by the USGS and cover nineteen states.
Level IV ecoregion frameworks have been developed by the US EPA for Alabama, Colorado, Delaware, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Massachusetts, Maryland, Mississippi, Montana, Nebraska, Nevada, North Carolina, North Dakota, Ohio, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Utah, Virginia, Washington, Wisconsin, West Virginia, Washington, and Wyoming; other projects are in progress for Arkansas, Texas, and Louisiana.
