Description
The Washington State Department of Ecology’s Aquatic Invasive Plant Management Grants Program supports work addressing invasive, non-native plants in Washington’s lakes, rivers, and streams. These plants threaten freshwater health, impair fish and wildlife habitat, and restrict recreation. The program provides financial and technical support through the Freshwater Aquatic Invasive Plant Management Program and Account, established by the Legislature in 1991.
Funding supports Integrated Aquatic Vegetation Management Plans, plant control, early infestation projects, education and outreach, and aquatic invasive plant research through demonstration or pilot projects. The state fiscal year 2028 competition emphasizes water body improvements, including ecological and habitat benefits, public use improvements, and benefits sustained after grant funding ends. Research may address benefits for susceptible water bodies rather than a single project water body.
