An aquatic invader is camping out on the banks of the Trent-Severn Waterway, and from the sounds of it, is getting very comfortable.
"We have been doing surveillance of this plant; it is the first known sighting in Canada," said Francine MacDonald, an aquatics biologist at the Ontario Federation of Anglers and Hunters who is an expert in invasive species.
