## What the grant funds

Golden Mussels (Limnoperna fortunei) are an aquatic freshwater/brackish invasive bivalve species first discovered in California"s Sacramento-San Joaquin Delta (Delta) on October 2024. This discovery is the first known occurrence of golden mussel in North America and was likely introduced to California via ballast water from a commercial ship traveling from an international port. Now that Golden Mussel are present in the Delta, they can be easily transported via trailered watercraft to areas that have not yet been invaded. This Request for Proposals (RFP) will fund projects in the listed principle areas of the Western United States towards the fulfillment of the top priorities similar to those identified in the State of California"s Golden Mussel Response Framework (April 14, 2025).
