Aquatic Invasive Plants Management Grants Program

The Aquatic Invasive Plants Management Grants Program aims to mitigate the threats posed by non-native aquatic plants to Washington's waterways. Established in 1991, it provides financial and technical assistance to control invasive species, with approximately $350,000 available annually. Grant recipients can receive up to $50,000 for early infestation projects. Notably, matching funds are no longer required, making it more accessible for communities to manage aquatic ecosystems effectively.

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.
