Aquatic invasive plants management grants program
Invasive, non-native aquatic plants are a serious threat to the health of lakes, rivers, and streams in Washington. Excessive invasive plant growth impairs fish and wildlife habitat, and restricts recreational activities.
In 1991, the Legislature established the Freshwater Aquatic Invasive Plant Management Program and Account to provide financial and technical support to tackle the problem statewide. The account provides funding for technical assistance, public education, and grants to help control aquatic invasive plants. Account revenue comes from a $3 fee on the yearly registration of boat trailers, which are the biggest carriers of aquatic invasive species.
