Angolan Miombo woodlands
Location and description
This area of savanna and woodland covers an area of plateau and gentle hills in central Angola, in the Cubango-Zambezi Basin which drains into the Zambezi River to the east. The area lies east of the range of hills that parallel the Atlantic coast and north of the Kalahari Desert reaching up as far as the rainforests of the Congo.
The flora is moist deciduous broadleaf savanna and woodland. Between these areas is open grassland. Three species of tree dominate miombo woodland: Brachystegia, Julbernardia, and Isoberlinia. Under the trees there is a rich variety of other flora while the grassland areas in the region lie on sandy soil. One particular feature of miombo woodland is its vulnerability to fire, as the area is dry most of the year round.
Fauna inhabiting the area include a number of bird species and mammals including the Giant Sable Antelope. Endemic mammals include Vernay's Climbing Mouse (Dendromus vernayi). Large mammals include Giraffe (in the wetter areas), Bushbuck (Tragelaphus scriptus), Blue duiker (Cephalophus monticola) and Yellow-backed Duiker (C. silvicultor) in the thickly wooded areas and giraffe, Sitatunga (Tragelaphus spekei) and waterbuck (Kobus ellipsiprymnus) in the wetter areas, with Tsessebe (Damaliscus lunatus) in the grasslands.
Other large mammals found in the ecoregion include hippopotamus (Hippopotamus amphibius), zebra (Equus burchellii), and their predators such as lion (Panthera leo), leopard (P. pardus), cheetah (Acinonyx jubatus), African wild dog (Lycaon pictus), Side-striped jackal (Canis adustus) and spotted hyaena (Crocuta crocuta) as well as smaller carnivores such as wild cat (Felis sylvestris), Serval (F. serval), caracal (F. caracal) and, appropriately the Angolan Genet (Genetta angolensis). Before the Angolan Civil War in the 1970s the area was home to large populations of elephants and black rhinoceros but these have almost completely been removed, mainly by poachers.
The only known endemic bird species is the Black-tailed Cisticola (Cisticola melanura) although there is a fairly rich selection of bird life. Following rains the following can be found in the wetlands: Greater Swamp-warbler (Acrocephalus rufescens), Yellow Flycatcher-warbler (Chloropeta natalensis), Chirping Cisticola (Cisticola pipiens), Bocage's Weaver (Ploceus temporalis), saddle-billed stork (Ephippiorhynchus senegalensis), Marabou Stork (Leptoptilos crumeniferus), Goliath heron (Ardea goliath), and wattled crane (Bugeranus carunculatus).
Urban areas and settlements
The intense and long-lasting civil war has caused immense damage to this environment, leaving the forests exposed to poaching and uncontrolled clearance, and conservation has obviously become a low priority issue for the government. Also due to this conflict the area cannot be properly studied by scientists. However the woodland is not threatened by clearance for agriculture or logging as along with the effects of war there are other factors keeping the population of the region to a minimum; the sandy soil does not sustain agriculture, and the woods and grassland are rife with tsetse fly. Some forest is being cleared on the edge of towns or for strip-mining.
There are a number of Angolan national parks in the area, but these have had to be abandoned at various periods due to the fighting. One of these in particular Cangandala National Park is an important haven for the Giant Sable Antelope.
