Site description This IBA is a discrete block of forest in the Ngerutechei area of Ngaremlengui. The site is bordered on the north and west by the Ngaremlengui Road and the Compact Road, respectively. To the east and south, the IBA extends to the edge of the land, not including the coastal mangroves. The Ngerutechei site is the only IBA on Babeldaob that includes significant riverine mangrove habitat. Mangroves, in general, are not well represented in Palau’s network of IBAs because the surveys that were used to identify IBAs did not include transects in the mangroves. The IBA includes the mountains of Etiruir, Tmerou, Sechedui and Ngeruach, which collectively form the highest areas in the state of Ngaremlengui.
