Ash Meadows National Wildlife Refuge.

In April 2002, volunteers donated over 200 hours to restore native plants at Ash Meadows National Wildlife Refuge (NWR) in Nevada. By working to revegetate the site, volunteers helped restore and recreate historical habitat in a system of springs and outflows called Point of Rocks for the endangered Ash Meadows Amargosa pupfish (Cyprinodon nevadensis mionectes) and the threatened Amargosa naucorid (Ambrysus amargosus), an aquatic insect.

Established in 1984, the refuge includes a total of 23,928 acres (9,683 hectares) of spring-fed wetlands and alkaline desert uplands. Ash Meadows NWR provides habitat for at least 24 plants and animals that occur only within the boundaries of the refuge. Twelve of those endemic species are listed as threatened or endangered under the Endangered Species Act (ESA).
