Site description The site lies on the escarpment zone where an area of about 200,000 ha of impoverished semi-deciduous moist forest (an outlier of Guinea–Congo forest) has the richest array of local endemics bird species in Angola. The rainfall is markedly seasonal, with November–December and February–April the months in which most rain falls. Tree genera in the forest include Ficus, Newtonia, Albizia, Celtis, Ceiba and Pterocarpus. Oil palms Elaeis are common, and epiphytes are abundant on the trees. Although the undergrowth of the forest has been cleared and the forest floor extensively planted with coffee, current coffee production is low, and much of the forested area is relatively undisturbed by human activity. However, valley bottoms in the area are now being cleared by subsistence farmers (Hawkins 1993) and this is a matter for some concern.
