San Joaquin River NWR Expansion

Current Status:Completed


The U.S. Fish and Wildlife Service (Service) today released a final plan authorizing the expansion of the San Joaquin River National Wildlife Refuge (NWR) by up to 10,738 acres. The expansion builds on the Service's and its partner's three decades of success at the Refuge, including implementation of the largest contiguous riparian restoration in California, which was funded entirely through grants.

The expansion area would link the Refuge with the Grasslands Ecological Area, a 160,000-acre mosaic of Central Valley floor habitats located in the historic floodplain of the San Joaquin River. This vast network of freshwater marshes, alkali grassland and riparian thickets is the result of decades of collaborative conservation involving private duck clubs, Grassland Water District, CA Department of Fish and Game, Natural Resources Conservation Service, CA State Parks, and the Fish and Wildlife Service.

Maintaining connectivity between the remaining natural areas and minimizing further fragmentation is crucial to the long term viability of California's natural heritage. Now that the plan has been approved, the Service can begin working with willing and interested landowners to expand the Refuge by up to 10,738 acres through acquisition of fee-title or conservation easements. Current Refuge staff would manage all acquired lands with existing resources.
