Ecoregion maps allow biologists to compare data across state lines

Federal and state researchers have collaborated with WED scientists to identify, map, and describe the ecoregions of Idaho. The Idaho project is part of a much larger effort by the EPA to create a national hierarchal ecoregion framework to facilitate research, assessment, monitoring, and management of the country’s environmental resources. 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 Idaho work involved researchers from WED, EPA Region 10, Idaho Division of Environmental Quality, U.S. Forest Service, U.S. Natural Resources Conservation Service, U.S. Bureau of Land Management, and the U.S. Geological Survey’s Earth Resources Observation Systems. It will be published as a double-sided, two-sheet poster by the USGS. The color poster includes an original 1:1,175,000-scale map that delineates the 10 level III and 70 level IV ecoregions of Idaho. Accompanying text and tables describe each ecoregion. It is the seventh in a series of ecoregion posters published by the USGS. The previous six cover nine states. (Contact: J.M.
