Mackinaw

Mackinaw State Forest encompasses 717,500 acres of public forest land in the northern portion of Michigan's Lower Peninsula, spanning eight counties from the Straits of Mackinac southward through some of the most scenic terrain in the northern Lower Peninsula. The forest preserves a diverse landscape of northern hardwood forests, jack pine plains, wetlands, and river corridors that includes portions of the renowned Jordan River Valley, consistently ranked among the most beautiful natural areas in Michigan. As one of the state's largest state forests, Mackinaw provides extensive recreational opportunities while managing habitat for two of Michigan's most critically endangered species.

Mackinaw State Forest is home to Michigan's two most critically endangered species: the Kirtland's warbler, which nests in young jack pine stands managed specifically for the bird, and Hungerford's crawling water beetle, one of the rarest insects in North America, found in only a handful of cold-water streams. White-tailed deer, black bears, coyotes, and bobcats are common throughout the forest, while the reintroduced elk herd in the Pigeon River Country State Forest on the eastern boundary represents Michigan's only free-ranging elk population. The Jordan River and other streams support wild populations of brook trout, brown trout, and steelhead, attracting predators including bald eagles, osprey, and river otters. Ruffed grouse and wild turkeys thrive in the young hardwood forests created by sustainable timber management practices.

The forest's vegetation spans a diverse range of northern Michigan plant communities, from the towering sugar maple and American beech stands of the mesic northern hardwood forests to the fire-dependent jack pine plains of the sandy outwash areas. Second-growth trees including aspen, paper birch, red maple, and various oaks dominate much of the forest, reflecting the regrowth that followed the old-growth logging era of the late 19th century. The Jordan River Valley supports old-growth white cedar swamps and northern white cedar forests along its banks, creating a microclimate that supports unusual plant communities including rare ferns and orchids. Extensive wetlands including bogs, fens, and cedar swamps occupy poorly drained basins throughout the forest, adding significant ecological diversity to the landscape.

The terrain of Mackinaw State Forest was shaped primarily by the Laurentide Ice Sheet during the Wisconsin glaciation, which deposited a complex array of moraines, outwash plains, and glacial lake deposits across the northern Lower Peninsula. The Jordan River Valley, perhaps the forest's most dramatic geological feature, is a deeply incised glacial meltwater channel that cuts through morainic hills, creating steep valley walls and a winding river course that drops over 200 feet in elevation over its length. Sandy outwash plains in the eastern portions of the forest support jack pine communities, while clay-rich glacial till on the moraines supports the richer hardwood forests. The Straits of Mackinac, at the forest's northern boundary, occupies a gap between the Upper and Lower Peninsula formed by glacial erosion through relatively soft bedrock.

Northern Michigan's continental climate brings long, cold winters and warm but brief summers to Mackinaw State Forest, with the Great Lakes significantly moderating temperature extremes near the coast. Winter temperatures average in the teens Fahrenheit from December through February, with annual snowfall ranging from 80 to over 150 inches depending on proximity to Lake Michigan's snowbelt. Summers bring average highs in the mid-70s to low 80s with moderate humidity, creating ideal conditions for hiking, fishing, and camping during the peak season from June through September. The lake-modified climate creates a longer growing season along the Lake Michigan shore, where fruit orchards thrive, compared to inland areas where earlier frosts limit the agricultural season.

The Straits of Mackinac area has been a crossroads of human activity for thousands of years, with Ojibwe, Odawa, and Potawatomi peoples establishing major settlements and trade centers at this strategic gateway between Lakes Michigan and Huron. French missionaries and fur traders arrived in the 17th century, establishing missions and trading posts that made the Mackinac region one of the most important centers of the North American fur trade. The logging era of the 1870s through 1910 transformed the landscape, as vast stands of white pine and red pine were felled and transported to sawmills via rivers, railroads, and the Great Lakes, fueling the rapid growth of cities across the Midwest. Much of the cutover land was seen as worthless after logging and was allowed to revert to state ownership through unpaid property taxes, laying the groundwork for today's state forest.

Mackinaw State Forest was assembled from tax-reverted cutover timberlands that accumulated in state ownership during the early 20th century, after logging companies abandoned lands stripped of their old-growth forests. The Civilian Conservation Corps planted millions of trees, built fire towers, constructed roads, and established campgrounds throughout the forest during the 1930s, transforming the degraded landscape into a managed public resource. The establishment of the Pigeon River Country State Forest on the eastern boundary in 1919, one of Michigan's earliest state forests, set a precedent for the broader state forest system that eventually encompassed the Mackinaw forests. Today the Michigan Department of Natural Resources manages the forest for multiple uses including sustainable timber production, recreation, wildlife habitat, and watershed protection.

The Jordan Valley Pathway, an 18-mile loop trail system that descends into the dramatic Jordan River Valley, is widely considered one of the finest hiking experiences in Michigan's Lower Peninsula. Deadman's Hill, a scenic overlook near Elmira at an elevation of 1,240 feet, provides breathtaking panoramic views of the Jordan River Valley, with the fall color display in October attracting thousands of visitors. Fifty miles of the North Country National Scenic Trail pass through the state forest, connecting it to the broader 4,600-mile trail system. The Pigeon River, Jordan River, and Sturgeon River provide outstanding fishing and paddling opportunities, while the forest's extensive trail network accommodates mountain biking, horseback riding, snowmobiling, and cross-country skiing.

Mackinaw State Forest operates numerous rustic campgrounds throughout its eight-county territory, offering primitive sites with vault toilets and hand-pump water at locations along rivers, lakes, and trail systems. The forest is accessible from Interstate 75 and US-31, with Mackinaw City, Petoskey, Gaylord, and Cheboygan serving as primary gateway communities offering full visitor services. The Mackinaw City office and Gaylord office provide forest information, permits, and maps. A Michigan Recreation Passport is required for vehicle entry to state forest campgrounds and day-use areas. The nearest airports with commercial service are Cherry Capital Airport in Traverse City and Pellston Regional Airport, both within 45 miles of the forest's boundaries.

Mackinaw State Forest's management addresses the unique challenge of maintaining habitat for two of Michigan's most endangered species while accommodating extensive public recreation and sustainable timber production. Kirtland's warbler management requires maintaining approximately 86,000 acres of jack pine habitat in age classes between 5 and 20 years through rotational harvest and replanting, a program that has helped the species recover from fewer than 200 pairs to over 2,000 pairs. Protection of Hungerford's crawling water beetle requires maintaining the cold-water stream habitats where this extremely rare insect survives, including careful management of forest practices in contributing watersheds. Sustainable forestry practices including selective harvest, prescribed fire, and forest health monitoring maintain the ecological diversity and economic productivity of the forest while building resilience against climate change impacts and emerging forest health threats.
