Minnesota bears outside their primary range

The Minnesota DNR has set up an interactive public database for reporting sightings of black bears outside their primary range.  On the map the area in black is the expected normal range; the diagonal line across the state represents approximately the boundary between the "north woods" ecosystems and the historical prairie and (further west) the Great Plains.  (You can see the continuation of the forested areas into Wisconsin and Canada from the green background of the original topo map.)
