The National Park of American Samoa is a National Park in the United States Territory of American Samoa, distributed across three separate islands, Tutuila, Ofu, and Ta‘ū. The park preserves and protects coral reefs, tropical rainforests, fruit bats, and it is popular for hiking and snorkeling. Of the parks 13,500 acres,9,000 acres is land and 4,500 acres is coral reefs, the park is the only American National Park Service system unit south of the equator. The National Park of American Samoa was established on October 31,1988 by Public Law 100-571 and this was resolved on September 9,1993, when the National Park Service entered into a 50-year lease for the park land from the Samoan village councils. In 2002, Congress approved a thirty percent expansion on Olosega, in 2009 an earthquake and tsunami produced several large waves, resulting in 34 confirmed deaths, more than a hundred injuries and the destruction of about 200 homes and businesses. The visitor center and main office were destroyed but there was one reported injury among the NPS staff. The Tutuila unit of the park is on the end of the island near Pago Pago. It is separated by Mount Alava and the Maugaloa Ridge and includes the Amalau Valley, Craggy Point, Tafeu Cove, and it is the only part of the park accessible by car and attracts the vast majority of visitors to the area. The park lands include a trail to the top of Mount Alava and historic World War II gun emplacement sites at Breakers Point, the trail runs along the ridge in dense forest, north of which the land slopes steeply away to the ocean. Ofu island is accessible via small fisherman boats from Tau island. Ta‘ū island can be reached by a flight from Tutuila to Fiti‘uta village on Ta‘ū, a trail runs from Saua around Si’u Point to the southern coastline and stairs to the 3, 170-foot summit of Lata Mountain. Because of its location, diversity among the terrestrial species is low. Approximately 30% of the plants and one species are endemic to the archipelago. Three species of bat are the native mammals, two large fruit bats and a small insectivore, the Pacific sheath-tailed bat. They serve an important role in pollinating the islands plants, the sheath-tailed bat was nearly eliminated by Cyclone Val in 1991. Native reptiles include the pelagic gecko, Polynesian gecko, mourning gecko, stump-toed gecko, Pacific boa, a major role for the park is to control and eradicate invasive plant and animal species such as feral pigs, which threaten the parks ecosystem. There are several species, the most predominant being the wattled honeyeater, Samoan starling. Other unusual birds include the Tahiti petrel, the spotless crake, the islands are mostly covered by tropical rainforest, including cloud forest on Tau and lowland ridge forest on Tutuila
