The Rare Species Guide (www.mndnr.gov/rsg) is an online reference tool, which was published in January 2009 by the Minnesota DNR's Division of Ecological Resources.
The interactive guide allows users to search for species profiles based on common or scientific name; state and federal endangerment status; broad taxonomic group (such as mammals or birds); habitat; location (including counties, watersheds, and ecological classification system subsections); and/or keyword. In addition to the species profiles, the Rare Species Guide also includes information on Minnesota's endangered species law and permits, why species become rare, and much more.
This Guide replaces and expands upon the 1988 DNR book, "Minnesota's Endangered Flora and Fauna."
The Rare Species Guide is available at no cost online at www.mndnr.gov/rsg.
