Michigan has over 19.3 million acres of forests covering more than half the land area of the state, mostly in the Upper Peninsula and northern Lower Peninsula. Four main types of forests found in Michigan include northern hardwoods, jack pine, oak-hickory, and boreal forests. These forests provide habitat to a diversity of plants and wildlife, including more than 75 different types of trees. In this module, learn how forests first grew (primary succession), where they are found in Michigan, about the different kinds of forests, and some of the many ways forests are important to people.
