Pacific Southwest Region manages 47 National Wildlife Refuges and three Wildlife Management Areas covering 2.3 million acres in California , Nevada and Oregon's Klamath Basin. These refuges range in size from the 1.6 million acre Desert National Wildlife Refuge near Las Vegas, Nevada, to the 13-acre Castle Rock National Wildlife Refuge, an island off the coast of northern California.
The refuges in our region span the many types of habitats, from wetlands, estuaries, rocky shores and grasslands to forests, deserts and all variations in between. Most refuges provide food, nesting grounds and resting areas for birds migrating to and from northern and southern climes.
