Cuyahoga Valley National Park's fields, forests, and wetlands are home to over 90 species of grasses and over 70 species of sedges.

While the natural vegetation of this region is forest, CVNP has one prairie, which was planted before the park was created. Situated on a disturbed area that was used as a borrow pit during construction of the Ohio Turnpike, this prairie is home to many species not commonly found in the area. The grasses of this area include big bluestem, little bluestem, switchgrass, and Indian grass.
