Harbor Island is located at latitude 46°03' and longitude 083° 46' in Potagannissing Bay north of Drummond Island, Chippewa County, Michigan. With approximately 300 ha (750 A) of land mass it is the largest of some 50+ islands in the bay, and as such is a significant reservoir for wildlife in the area (it is the only island known to support a deer population throughout the winter) and is most representative of the habitats indigenous to the islands in this region of the U.S. Great Lakes. Harbor Island supports the major regional habitat types: mixed upland forest (oak-maple), mid-seral stage forest (aspen-ash-birch), boreal forest (cedar-balsam fir), old field (grass-herb) and marsh (rush-pondweed). Excluded on Harbor Island are the sand beaches and low dunes found on the north shores of Lake Huron along Michigan's upper peninsula. Having the highest elevation (680' above sea level) of all the islands in the bay, Harbor Island supports the greatest growths of deciduous species such as oak and maple, thus providing another niche, exploitable by both breeding and migrating avian species, not available on many of the adjacent islands.
