Hydrilla: The Hunt is on in Ohio
Recognized as one of the world’s worst weeds, Hydrilla verticillata has a devastating impact on freshwater resources. Our desirable native aquatic plants, sport fishing, native wildlife, waterfront property values, and recreational uses might all be seriously impacted should Hydrilla spread.
The photos below illustrate how dense hydrilla can grow in a very short period of time: just 18 days elapsed between the two photos!
The perfect water weed
Hydrilla can grow in all of Ohio’s freshwater habitats. It is capable of reproducing in many ways: from small fragments to subterranean tubers that can survive for years in little water. It is costly and frustrating to remove. It has been detected in three major watersheds (Chagrin, Cuyahoga, Rocky) and we would like to stop its spread before it enters into Lake Erie.

The Hydrilla detection and rapid response program is coordinated by the Cleveland Metroparks with support from the Crooked River Cooperative Weed Management Area. The United States Environmental Protection Agency funded this project.
