The Essex Region Conservation Authority (ERCA) is working closely with the Ministry of Natural Resources, the Invasive Species Centre, the Ontario Federation of Anglers and Hunters and many other partners to evaluate the extent of the infestation, contain the spread, and develop plans to control this invasive species. To date, surveys have shown the infestation to be limited to the contained wetland area of the West Cell of Hillman Marsh that is not directly connected to Lake Erie.
