 Anacapa and several other islands were collectively designated as Channel Islands National Monument in 1938, though the Coast Guard retained responsibility for the Anacapa lighthouse.Now fully automated and unmanned, the light house still operates, but the National Park Service (NPS) is responsible for Channel Islands National Park.Anacapa Island is noted now for an environmental restoration program devised by the NPS to exterminate the large population of non-native rats which infested the island and was making significant inroads on native species.
