Site description The Moloka`i Forests Important Bird Area contains most of the native forest remaining on the island. It is 12,295 hectares in size, and extends from near sea level in several locations on the northern shore of the island to the highest summits on the island, Kamakou at 1514 meters (4970 feet) and Olokui at 1404 meters (4606 feet). The terrain is extremely rugged, with narrow ridges separated by deep stream valleys. Sea cliffs over 600 meters (2000 feet) tall, some of the highest in the world, occur in several locations along the northern coastline. Annual rainfall ranges from about one meter in the southwestern part of the area to over four meters at the head of Wailau Valley east of Olokui. Much of the area is covered in dense forest. Invasive alien plants dominate much of the lowlands, but the higher elevations contain primarily intact native forest and shrubland. The Olokui Plateau is an isolated mountain with steep sides that restrict access to alien ungulates, and is one of the most pristine areas in Hawai`i. Despite the high quality native forests that occur in parts of the area, only a few native bird species are left on Moloka`i due to the high prevalence of diseases carried by alien mosquitoes. The area includes the upper elevations of Kalaupapa National Historical Park, Olokui and Pu`u Ali`i State Natural Area Reserves, most of the Moloka`i State Forest Reserve, Kamakou and Pelekunu Nature Conservancy Preserves, and a small amount of private land.
