Cooperrider-Kent Bog (Tom S.) State Nature Preserve

Kent Bog is a living relict from the Ice Age. In glacial times, the boreal forest, including tamarack, dominated the landscape far south of northern Ohio. Today, however, Kent Bog supports the largest, southernmost stand of tamarack in the continental United States.

There are over 3,500 tamaracks in the population with many robust seedlings growing among the larger trees. Here, too, is a fine population of gray birch, also a tree of more northern distribution. Gray Birch and tamarack are both potentially threatened species in Ohio.
