Pathway of Introduction and Spread
Introduced through the dumping of aquarium contents. Motorboat traffic contributes to natural fragmentation and the distribution of fragments throughout lakes. Can also spread via attaching to boats, trailers and other aquatic equipment.
Competes aggressively to displace and reduce the diversity of native aquatic plants. Spring growth begins earlier than other plants and quickly grows to the surface, forming dense canopies that overtop and shade the surrounding plants. Dense beds restrict swimming, fishing, boating and clog water intake pipes of industries and irrigators.
