The site lies to the north of the Fure River (GH012) and Fure Headwaters Forest Reserves, the three forming an almost continuous crescent-shaped block. The terrain is hilly, with the hills strongly dissected by steep-sided deep valleys. These valleys become flooded during the rainy season, creating swampy habitats. The reserve includes both moist evergreen and wet evergreen forest. Much of the forest, especially along the ridges which are inaccessible to logging, remains intact. The site includes c.2.3 ha of plantation and a few farms.
