Team is first to find invasive hydrilla plant in Canada

Hydrilla verticillate (hydrilla), one of North America's most invasive species, has been found for the first time in Canada. Dr. Rebecca Rooney, a biology professor, and members of her Waterloo Wetland Laboratory were surveying a secluded section of the Hillman Marsh Conservation Area in Leamington, Ontario, when they found the unexpected species. Upon review, the Ministry of Natural Resources and Forestry confirmed their findings.
