Angolan montane forest-grassland mosaic

These inland slopes are mostly covered with grassland and savanna. The woodland once covered a much larger area but today only patches survive, mainly in deep ravines and on the higher peaks in Huambo and Cuanza Sul provinces, such as Mount Moco, and on the Serra da Chela in Huíla Province.

The area has a wet summer and some mist and rainfall year-round so water is fairly abundant though in the dry season obtainable in some places only by digging in the sandy beds of the rivers. [1]

The towns of Huambo and Lubango are located at the edge of the ecoregion.

In the dry season fires are common and the dry grasses burn and are then renewed. The trees are not so vulnerable to fire. The woodland flora has similarities with other mountain ranges spread across Africa. Plants on the inland ridge include the shrubs such as Ericas, sugarbushes (Protea) and Cliffortias, and grasses Themeda triandra, Tristachyas, Hyparrhenias, Festucas, and Monocymbium.[1]

The fauna includes a number of bird species unique to the highlands such as Boulton's batis (Batis margaritae), Swierstra's spurfowl (Pternistis swierstra), Angola cave-chat (Xenocopsychus ansorgei) grey-striped spurfowl (Pternistis griseostriatus) and Angola slaty flycatcher (Dioptrornis brunneus)..[1] Some of these species have close relatives in other forests of the continent, more indication that this woodland was once much more widespread. The hills were home to large mammals such as zebras and antelopes until recently.

The highlands are one of the most heavily populated parts of Angola so the woodland is vulnerable to clearance for logging, while some of the grassland, except where it is very swampy, is being cleared for agriculture. Furthermore, the mountains were the scene of much conflict and poverty during the Angolan Civil War and as a consequence the wildlife has been little studied or protected.[1]
