"The Nature Conservancy—together with the National Park ServiceU.S. Fish and Wildlife Service and the California Department of Fish and Game—engaged in an intensive, science-based recovery project to save the island fox. In less than a decade, the fox population has made an unprecedented recovery—heralding it as one of the fastest and most successful endangered species recovery programs in U.S. history.”
