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 National Wetland Condition Assessment (NWCA) is a statistical survey that begins to address some of the gaps in our understanding of wetland health by providing information on the ecological condition of the nation's wetlands and stressors most commonly associated with poor condition. The NWCA is designed to answer basic questions about the extent to which our nation's wetlands support healthy ecological conditions and the prevalence of key stressors at the national and regional scale. It is intended to complement and build upon the achievements of the U.S. Fish and Wildlife Service Wetland Status and Trends Program, which characterizes changes in wetland acreage across the conterminous United States. Paired together, these two efforts provide government agencies, wetland scientists, and the public with comparable, scientifically defensible information documenting the current status and, ultimately, trends in both wetland quantity (i.e., area) and quality (i.e., ecological condition).
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.
The Delta Juvenile Fish Monitoring Program (DJFMP) has monitored natural-origin and hatchery-origin juvenile Chinook Salmon (Oncorhynchus tshawytscha) and other fish species within the San Francisco Estuary (SFE) since 1976 using a combination of midwater trawls and beach seines. Since 2000, three trawl sites and at least 58 beach seine sites have been sampled weekly or biweekly within the SFE and lower Sacramento and San Joaquin Rivers. The main objectives of the DJFMP are: 1. Document the long-term abundance and distribution of juvenile Chinook Salmon in the Delta. 2. Comprehensively monitor throughout the year to document the presence of all races of juvenile Chinook Salmon. 3. Intensively monitor juvenile Chinook salmon during the fall and winter months for use in managing water project operations (Delta Cross Channel gates and water export levels) on a real-time basis. 4. Document the abundance and distribution of Steelhead. 5. Document the abundance and distribution of non-salmonid species.
