University of Michigan Biological Station

It is located on the south shore of Douglas Lake in Cheboygan County, Michigan.

Its field researchers are gauging the impact of global warming and increased levels of atmospheric carbon dioxide on the ecosystem of the upper Great Lakes region, and are using field data to improve the computer models used to forecast further change.

One of these, a two and a half mile stretch downstream from the Douglas Road crossing of the East Branch of the Maple River supports the only stable population of the Hungerford's Crawling Water Beetle, with roughly 1000 specimens.

This area, though technically not part of the UMBS is largely within and along the boundary of the University of Michigan Biological Station.

UMBS is also the home of the Great Lakes Piping Plover captive rearing facility.
