Cuyahoga River

The Cuyahoga River winds its way through Cuyahoga Valley National Park.

The Cuyahoga River Valley
Twenty-two miles of the Cuyahoga River wind and weave through the Cuyahoga Valley, forming the backbone of Cuyahoga Valley National Park (CVNP). The river, with its associated riparian habitat, is just one element of the park’s habitat mosaic. From deciduous mixed-mesophytic forests to wetland habitats, from currently cultivated agricultural lands to older field habitats in various stages of succession, the park’s habitats provide opportunities for plants and animals to flourish.

Over 900 plant species are found in the park, as well as 194 species of birds, 91 aquatic macroinvertebrates, 43 fish, 32 mammals, 22 amphibians, and 20 species of reptiles. Read about how our scientists inventory and monitor (I&M) species to build a strong scientific foundation for the management and protection of natural resources in the park.

CVNP is much more than a list of species. It contains a truly unique physical environment, formed by the mingling of two diverse geographic regions—the Appalachian Plateau and the Central Lowlands—modified by the comings and goings of multiple glaciations. High above the Cuyahoga River, the landscape is rugged, with steep-sided valleys backed by high, narrow hills. Closely spaced ravines funnel tributaries, some of which drop up to 600 feet in a distance of only a few miles, toward the crooked river. Read more about CVNP's geology in our Rock, Ice, and River site bulletin. (720 KB)

During the Great Depression, the "boys of Company 567" of the Civilian Conservation Corps helped shape the landscape that would later become Cuyahoga Valley National Park by constructing buildings, playfields, and a lake, as well as planting over 100 acres of trees.
