Ngeremlengui (also spelled Ngaremlengui,) is one of Palau's sixteen states. It has a population of 350 (according to the 2015 census), and is just west of the capital in Melekeok state. Geography Ngeremlengui, located on the north-central west coast, includes the large hill mass of Roismlengui and vast tracts of the interior along the Ngermeskang River. The modern villages of Ngeremlengui include inhabited settlements at Ngermetengel, Imeong,and Ngchemesed. Along the west coast between the inlet to Ngeremeduu Bay and the Chometubet River, the terrain is very rugged with some of the highest hills in Palau including Badechemetei. Ngermetengel is located on the north side of the Chometubet, and Imeong is located a short distance to the northeast on the Imeong River. Ngchemesed is located on the north shore of Ngeremeduu Bay. To the north, the Kaud River has been considered the boundary between Ngeremlengui and Ngardmau. Inland, the rolling hills rise to the highest points in Palau with elevations of 250m near the border with Ngardmau. In the east part of Ngeremlengui is the drainage of the Ngermeskang River, the longest in Palau. This drainage is separated from Ngermetengel and Imeong by a line ofprominent hills collectively known as Roismlengui. To the southeast is the Ngerbechederngul River, better known as the Yamato, which joins the Ngermeskang near its mouth at the northeast corner of Ngeremeduu Bay. During the Japanese administration, Ngeremlengui was connected by road to Ngatpang, Melekeok, and Ngardmau, but today most of the roads are impassable. Thick fringes of mangrove swamp forest are found along the Ngermeskang and Ngerbechederngul Rivers in the northeast corner of Ngeremeduu Bay and along the northern coast. Along a broad belt of low hills inland of the mangroves are large areas of savanna with patches of forest. Further inland, large tracts of forest cover much of the interior part of the state. According to informants, areas of savanna along the Ngermeskang River were created recently in the construction of the Japanese Asahi Plantation. Presently, most of the use of land in Ngeremlengui is confined to gardens surrounding the modern villages of Ngermetengel, Imeong, and Ngchemesed. Interspersed with these kitchen gardens are stands of agroforest which include coconut, betelnut, breadfruit, and almond trees, and banana plants. In and around many of the uninhabited villages are stands of coconut and betelnut palms, and occasionally patches of irregularly attended taro swamp gardens. According to informants, except
