Invasive Hydrilla detected for the first time in Ontario

Invasive Hydrilla has been detected for the first time in Hillman Marsh, in Southern Ontario, by Waterloo Wetland Lab researchers.

Hydrilla, an aquatic plant species, poses a significant risk to wetlands by out-competing native plant species and clogging waterways. To help prevent its spread, we urge everyone to clean, drain and dry equipment after use.

Learn more about Hydrilla from the Essex Region Conservation Authority, and listen to Dr. Rebecca Rooney's interview on CBC Radio for more information.
