This NA protects a variety of riparian habitats on the islands and peninsulas of Upper Mann Lake. It consists of moderately to strongly rolling till substrate and cobble and sand beaches. Besides aquatic vegetation and emergents such as cattails and bulrushes, the vegetation includes willow shrublands in low-lying areas and along the lakeshore along with reedgrass meadows. On higher ground there is mixedwood forest of aspen, balsam poplar, birch and white spruce, aspen stands with diverse shrubs, and mixed shrublands. The site also features an unusual abundance of mature birch.
Upper and Lower Mann Lakes are shallow lakes set in rolling, wooded country. The lakes were named after Sir Donald Mann (1853-1934), a vice-president of the Canadian Northern Railway Company, which built a rail line close to Upper Mann Lake in the early 1900s. Before the advent of the railway, the lakes were collectively called Island Lake because they became one large lake with a central island when the water level was high .
Irregularly-Shaped Upper Mann Lake has numerous bays and islands. The lake is moderately developed on the north and west shore, but further development is precluded by the presence of the Upper Mann Lake Natural Area .
