The biological and ecological baseline characteristics of the Duette mine property are treated under three major headings: Land (Description of terrestrial plant and animal communities); Land-Water Interface (Description of plant and animal communities inhabiting swamps and marshes); and, Water (Description of aquatic plant and animal communities). Initial field reconnaissance revealed four land communities and three land-water interface communities. In addition, aquatic vegetation occurred in the streams, and ruderal vegetation occupied those sites where the land communities had been disturbed by intensive land use. Except for aquatic vegetation, these vegetation types were discernible from aerial photographs. A vegetation map was prepared from these photographs and the acreage of each type determined.
