Abstract Ecoregion frameworks are valuable tools for inventorying and assessing environmental resources, for setting resource management goals, and for developing biological criteria and water quality standards. In a collaborative project between the Iowa Dept. of Natural Resources (DNR) and the the EPA's three major ecological regions of Iowa and defined six subregions of the Western Corn Belt Plains ecoregion within the state. Lists of candidate stream reference sites have been developed for seven regions, and the sites were visited and evaluated by Iowa DNR and U.S. EPA personnel to determine their suitability for sampling. The Iowa DNR plans to use the ecoregions and reference sites to better understand regional variations in stream quality, to assess attainable conditions, to develop biological criteria, and as a framework to report on water quality.
