San Joaquin River National Wildlife Refuge, Nature reserve in San Joaquin County, United States.
San Joaquin River National Wildlife Refuge is a protected area in Stanislaus County, California, located where the San Joaquin, Stanislaus, and Tuolumne rivers meet. The land takes in river bottomlands, wetlands, and open grasslands that together support a wide range of plant and animal life.
The refuge was established in 1987, mainly to address the sharp decline of goose populations and other native species that had lost much of their natural habitat across the Central Valley. Over the following decades it became a recovery area where animal populations and river ecosystems gradually rebuilt.
The refuge sits along the Pacific Flyway, one of the main routes that migratory birds follow along the west coast of North America. Visitors who come in fall or winter can watch tens of thousands of geese and ducks resting and feeding across the wetlands.
A marked trail runs through the different habitat zones of the refuge, with the best wildlife sightings typically happening in the early morning or late afternoon. Fall and winter bring the largest numbers of migratory birds, making those seasons a good time to visit.
The riverside forest along the San Joaquin is part of one of the largest riparian woodland restoration projects in California, with hundreds of thousands of native trees planted over many years. These trees have changed the look of the land completely, and animals that depend on dense riverside vegetation have returned in large numbers.
