San Luis National Wildlife Refuge Complex Final Comprehensive Conservation Plan and Environmental Assessment

This Comprehensive Conservation Plan (CCP) will guide the management of the Merced National Wildlife Refuge (NWR), San Luis NWR and Grasslands Wildlife Management Area (WMA) for the next 15 years. Located in Merced County, California (Figure 1-1), these three units are managed and administered by the San Luis National Wildlife Refuge Complex (the Complex). A fourth unit, the San Joaquin River NWR, is also managed and administered by the Complex but already has a CCP for its management, which was completed in 2006 and amended in 2022. For the sake of this document, the term Complex refers to the San Luis NWR, Merced NWR and Grasslands WMA only. The Complex comprises just four of the 568 refuges that currently make up the U.S. Fish and Wildlife Service (USFWS or the Service) National Wildlife Refuge System (NWRS or Refuge System). The mission of the NWRS is to conserve a network of lands and water for the conservation and management of fish, wildlife and plant resources of the United States for the benefit of present and future generations. As part of the Refuge System, the three units—Merced NWR, San Luis NWR and Grasslands WMA—addressed in this CCP provide important habitat for a unique assemblage of both wetland- (particularly waterfowl and other waterbirds) and upland-dependent wildlife species of California’s Central Valley.

This CCP is divided into five chapters: Chapter 1, Introduction and Background; Chapter 2, Comprehensive Conservation Planning Process; Chapter 3, Refuge Resources; Chapter 4, Refuge Management Direction; and Chapter 5, Implementation.
