Angolan mopane woodlands(Redirected from Angolan Mopane woodlands)
Angolan mopane woodlands are situated in southwestern Angola, extending into northern Namibia. This ecosystem surrounds Etosha Pan, which is considered a separate ecoregion. The mopane trees are the main type of vegetation.
Location and descriptionEdit
In Angola the region mostly comprises the southern Cunene Province and in Namibia in the regions of Omusati, Oshana and the eastern inland arm of Kunene and areas of Oshikoto surrounding the Etosha Pan. The ecoregion includes the Cunene River which divides the two countries, and is one of the main sources of water in this dry region. The landscape is mainly flat. The rainy season is late summer.
Mopane is the distinctive feature, a single-stemmed tree in some places up to 10 m high and in some places not much more than a shrub. It has butterfly-shaped leaves and grows in dense thickets. In Etosha National Park in Namibia it is by the far the most common species.
Fauna include large mammals, many of which can be seen in Etosha National Park. The ecoregion contains elephants, who crash through the mopane trees and feed on their bark and leaves, black rhino, zebra, cheetahs, leopards, lions, and many antelopes. There are four mammals which are almost endemic to the ecoregion: Thomas's rock rat (Aethomys thomasi), heather shrew (Crocidura erica), blackish white-toothed shrew (Crocidura nigricans), and the black-faced impala. The mopane trees are the habitat of the mopane emperor moth (gonimbrasia belina), whose caterpillars feed on the leaves and are collected for food by people in the area. The area is rich in bird life, insects (particularly spiders) and reptiles including four endemic reptiles: Afrogecko ansorgii, Coluber zebrinus, Ruben's sand lizard (Pedioplanis rubens), and the skaapsteker snake (Psammophylax rhombeatus ocellatus).
Threats and preservationEdit
The woodlands are vulnerable to clearance for agriculture, firewood and timber while the grassland between the trees is being overgrazed. On the Angolan side there are two national parks, Bicauri National Park and Mupa National Park but wildlife in these parks and Cunene Province as a whole has been severely damaged by the Angolan Civil War.
Meanwhile in Namibia a huge game reserve contained a large proportion of this ecoregion until the park was broken up to create land for settlements in the 1960s. Part of the reserve remains protected as Etosha National Park and this includes a large area of mopane woodland but the widespread poaching and uncontrolled hunting which began with the dismantling of the reserve and the Namibian War of Independence still continues in Etosha and other private reserves in Namibia. There have also been outbreaks of anthrax in Etosha National Park. On the positive side firefighting efforts have allowed the park to become more wooded and thus support a larger elephant population.
