The overarching AIS goal is that "Risks of aquatic invasive species invasions are substantially reduced, and their economic, ecological, and human health impacts are minimized. This goal is addressed through a series of performance and workload measures. The AIS Program provides funding for Aquatic Invasive Species Coordinators for each Region within the Service and their respective aquatic nuisance species activities. These coordinators work closely with the public and private sector to develop and implement invasive species projects. One of the primary initiatives of the program is the prevention of invasive species via boats through the "100th Meridian Initiative" (overseen by individual AIS regional coordinators). This initiative aims to prevent the spread of aquatic invasive species by boats personal watercraft and other pathways. Through boat inspections and boaters assessments along the 100th meridian, partners can learn how to prevent the spread of zebra mussels and other AIS via transport of boats and personal watercraft.
The Environmental Monitoring Program (EMP) began in 1975 to conduct baseline and compliance monitoring of water quality, phytoplankton, zooplankton, and benthic invertebrates in the San Francisco Bay-Delta estuary. This monitoring program was designed to track the impact of water diversions to the State Water Project (SWP) and Central Valley Project (CVP) on the Bay-Delta. In the decades since, EMP scientists have monitored these constituents at fixed and floating stations throughout the estuary and ensured compliance with state and federal mandates such as Water Right Decision 1641 (D-1641). In the years and decades since its inception, EMP has become one of the cornerstones for scientists' and managers' understanding of the pace and pattern of change in this critical ecosystem. By sampling water quality and biological communities concurrently, EMP has created a dataset that is uniquely useful in better understanding causal connections between physical, biological, and biogeochemical processes.
