The Cuyahoga River Valley
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 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.
