What Are Invasive Species?
Some plants are beneficial in ponds, providing food and shelter for things living in the pond. Others, that we refer to as “invasive,” “exotic,” or “nonnative” cause problems (e.g. hydrilla, purple loosestrife and the common reed).
Most of these invasive plants come from Europe or Asia and enter our ponds in a number of ways – e.g. through the emptying of aquariums or water garden plants into the pond and also on boat hulls, propellers, and trailers.

What Can You Do to Help?
Pond residents can combat invasive species through education, prevention and eradication. Boat owners can help by cleaning their boats properly, removing plant particles, washing down boats with hot water or high pressure and letting hulls dry off.
