Site description The Kaua`i Forests and Uplands Important Bird Area occupies most of the central and northwestern portions of Kaua`i and contains most of the native forest and intact upland habitats remaining on the island. It is 77,420 hectares (191,227 acres) in size and extends from sea level along the northwestern coastline to the highest summits, Wai`ale`ale at 1569 meters (5148 feet) and Kawaikini at 1598 meters (5243 feet). The core of the area is the broad Alaka`i Plateau that slopes gradually downward from east to west. The terrain is extremely rugged, with deep canyons eroded into the plateau on all sides, including spectacular Waimea and Olokele Canyons on the south and the dramatic Na Pali coastline on the northwest. These canyons contain numerous waterfalls, isolated hanging valleys, and precipitous cliffs over 600 meters (2000 feet) high. Annual rainfall ranges from about one meter (39.3 inches) in the southwest to 11.5 meters (450 inches) near the summit of Wai`ale`ale, one of the wettest spots on earth. Even the relatively flat Alaka`i Plateau is etched with innumerable streams and narrow gulches that make pedestrian access challenging. Much of the area is covered in dense forest and montane shrubland. Bogs with stunted vegetation occupy some depressions in the plateau. The higher elevations contain some of the most intact native ecosystems in Hawai`i, but invasive alien plants dominate much of the lowlands. The area includes the State Alaka`i Wilderness Preserve, the State Hono `O Na Pali and Kuia Natural Area Reserves, all or part of the Halelea, Moloa`a, Na Pali-Kona, Kealia, Pu`u Ka Pele, and Lihue-Koloa State Forest Reserves, Koke`e, Waimea Canyon, Haena, Na Pali Coast, and Polihale State Parks, Wailua, Kekaha, and Mokihana State Game Management Areas, and The Nature Conservancy?s Kana`ele Preserve.
