With its long history of disturbance, Cuyahoga Valley National Park contains a number of nonnative species.
The new pest is the emerald ash borer, an Asian wood-boring beetle that kills ash trees three to five years after infestation. Adults are dark metallic green, and fly from May through September to ash trees to mate and lay eggs. Larvae emerge and tunnel beneath the bark, chewing on vascular tissue and interrupting the tree’s circulatory system. An infestation only becomes apparent once the canopy thins, branches die back, and death begins. By then, the insect has long since moved on. The emerald ash borer has already killed millions of ash trees from Illinois to Maryland and up into Ontario. It is in at least 26 Ohio counties, including those in and near CVNP. The Ohio Department of Agriculture prohibits the transportation of ash tree materials and all non-coniferous firewood out of quarantined areas.
These and other nonnative species in CVNP are evaluated and monitored by resources management staff. As directed by the park’s general management plan, exotic plant and animal species are controlled or eradicated when possible.
