Au Sable State Forest

The Au Sable State Forest is a state forest in the north-central Lower Peninsula of Michigan. It is operated by the Michigan Department of Natural Resources.
The Au Sable State Forest is a byproduct of the lumbering boom in Michigan during the late 19th century. Many parcels of old growth timber were stripped of their largest trees. After forest fires had consumed the resulting detritus, the land had no economic value. Typically, it was sold to subsistence farmers or was reverted to the state in lieu of unpaid property taxes.
Today, the Au Sable State Forest is a valuable asset to the state of Michigan. Much of it surrounds the fast-growing communities of Houghton Lake, Higgins Lake and Lake St. Helen adjacent to Interstate 75. In addition, much of the forest is used for wildlife game management and the fostering of rare and endangered species, such as the Kirtland's warbler. Much of the area sits on the "Grayling outwash plain", a unique habitat.
