The Minnesota County Biological Survey (MCBS) is an ongoing effort begun in 1987 by the Minnesota Department of Natural Resources (DNR) that is systematically surveying, county-by-county, the state's natural habitats. The effort identifies significant natural areas and collects and interprets data on the status, distribution, and ecology of plants, animals, and native plant communities throughout the state. Through 2009 surveys have been completed in 74 of Minnesota's 87 counties and have added nearly 17,000 new records of rare features to the DNR's information systems.
Native trout require clean, cold water that usually originates from springs, but the springs feeding the 173 designated trout streams in southeastern Minnesota are under increasing pressure from current and expected changes in land use. This joint effort by the University of Minnesota and the Minnesota Department of Natural Resources is working to identify and map the springs and the areas that feed water to these springs and to learn how these waters might be affected by development and water use.
Endocrine disrupting contaminants are chemicals that may interfere with natural hormones in humans and wildlife and produce adverse developmental, reproductive, neurological, and immune effects. These chemicals occur in a variety of everyday products, including pharmaceuticals, plastics, detergents, flame retardants, cosmetics, and pesticides. As these chemicals get discharged into the environment, humans and wildlife are exposed. The U.S. Geological Survey and St.
