General characteristics

Several vegetation zones meet in western Angola: it is bounded to the north by the lowland rain forests of the Za

Restricted-range species

Angola is among Africa's ornithologically least-known countries (Dowsett 1985, Dean et al. 1987). In the arid lowlands (see 'Habitat associations' table), Euplectes aureus is found in northern and central Angola below the escarpment zone, but most records of Estrilda thomensis are from south-west Angola and along the Angola-Namibia border, further south than any of the other restricted-range species. Seven species appear confined to the semi-evergreen forests of the escarpment zone, and Platysteira albifrons is only in the escarpment forest and coastal lowland gallery forest; note that, according to Lippens and Wille (1976), this species occurs in extreme south-west Za

Threat and conservation

The density of Angola's human population is relatively low, but some of the EBA's most important forests are believed threatened. For example, the montane forests on Mt Moco in the Bailundu highlands (which are the EBA's best remaining examples of this forest type: Huntley 1992) are small and are vulnerable to fire and felling (Dowsett 1985). The escarpment zone was developed for coffee-growing from the 1930s, and by the 1970s there was little undisturbed forest remaining; it was estimated then that 95% of forest was under coffee production (which leaves the canopy largely intact), although much of this has now been abandoned for 30 years or more, with (possibly much) less than 25% now producing coffee. Clearance for subsistence agriculture is now a threat, and an estimated 30% of the forest has been so used; some forms of agriculture leave some canopy trees, but others remove virtually all of them. Hunting for food is probably widespread (Hawkins 1993).

All seven restricted-range birds confined to escarpment forest, and the montane Francolinus swierstrai, are threatened by habitat pressures, and the two francolins are also probably widely hunted. A more-widespread threatened species in montane habitats in the Bailundu highlands is Black-chinned Weaver Ploceus nigrimentum (classified as Vulnerable).

There are several protected areas in the EBA, but a number of new ones have been proposed to improve coverage of key habitats (Huntley 1992; see also Collar and Stuart 1988, IUCN 1992b). Kisama National Park includes an area of escarpment forest, but probably supports only a few of the restricted-range species, so Gabela and Chongoroi Strict Nature Reserves and Tala Mungongo National Monument have been proposed as new conservation areas. It may also prove possible to designate most of the southern part of the escarpment as a Biosphere Reserve (Hawkins 1993). The Afromontane habitats of western Angola are currently unprotected, so Namba and Monte Moco Strict Nature Reserves and Tundavala Regional Nature Park have been proposed. Estrilda thomensis occurs in Iona National Parks, and Chimalavera Regional Nature Park may support all three of the lowland species. The proposed Serra de Neve Strict Nature Reserve could also support some restricted-range species.
