About the Complex


San Luis National Wildlife Refuge Complex

The San Joaquin River NWR is managed as part of the San Luis NWR Complex. A National Wildlife Refuge Complex is an administrative grouping of two or more refuges, wildlife management areas or other refuge conservation areas that are primarily managed from a central office location. Refuges are grouped into a complex structure because they occur in a similar ecological region, such as a watershed or specific habitat type, and have a related purpose and management needs. Typically, a project leader or complex manager oversees the general management of all refuges within the complex and refuge managers are responsible for operations at specific refuges. Supporting staff, composed of administrative, law enforcement, refuge manager, biological, fire, visitor services, and maintenance professionals, are centrally located and support all refuges within the complex.

Other units in the San Luis NWR Complex include the San Luis NWR, Merced NWR, and Grasslands Wildlife Management Area. The Refuge Complex headquarters is located at the San Luis NWR: 7376 S. Wolfsen Road, Los Banos, CA 93635. Contact us by phone at 209/826-3508 or mail at PO Box 2176, Los Banos, CA 93635.
