The Cooperrider-Kent Bog State Nature Preserve is state nature preserve located mainly in Kent, Ohio. The preserve surrounds the Kent Bog, a remnant of the Wisconsin Glaciation. It is a true bog with acidic waters, and unique environmental conditions have enabled it to survive. The bog contains the largest stand of tamarack trees in the state of Ohio.
