Huron-Manistee National Forest (7,689 acres)

Candidate RNA Size (acres) Description
Bear Swamp (includes Yonker's Meadow) 2139 A rich conifer swamp, a southern swamp, and intermittent wetlands. Five rare plant species and one rare animal species are known to inhabit these areas.
Big South (includes Whelan Lake) 1842 Contains several vegetative communities including a bog, intermittent wetland, oak-pine barrens, southern floodplain forest, and emergent marsh. This area represents a large, diverse, highly undisturbed floodplain with high floral and faunal diversity.
Black River Complex 750 Globally rare wooded dune and swale complex along the Lake Huron shoreline
Blockhouse Swamp 1010 Rich conifer swamp and a small mesic northern forest.
Brandybrook 1300 Located on poorly drained glacial outwash sands and includes a complex of wetland communities, of which five are considered high quality natural communities.
McDonald Creek Forest 103 Dry-mesic northern forest with mature white pine, aspen and some red pine. Currently the best identified representative of white pine-aspen forest located in the Harrisville Moraines Subsection.
O’Brien Lake Forest and Swamp 130 Dry-mesic northern forest dominated by red pine some of which are over 100 years old, and a poor conifer swamp dominated by black spruce. The best known example of a poor conifer swamp in the Mio Outwash Plains Subsection.
South Olga Bog 30 Located in Big Rapids loamy moraine subsection.
Trout Lake Swamp 185 Second-growth hardwood-conifer swamp dominated by northern white cedar, black ash, balsam fir, and black spruce. This area is primarily in an undegraded state and contains a high level of diversity.
Vaughn Lake 200 A high quality, highly diverse bog surrounded by a forested zone of tamarack, black spruce, white pine, and red maple. The sandy uplands around the forested wet zone support a dry-mesic forest.
