The driest areas usually receive 110–200 mm (4.3–7.9 in) of rain per year, [1] and the wettest just a little over 500 mm (20 in). The surrounding Kalahari Basin covers over 2,500,000 km 2 (970,000 sq mi) extending farther into Botswana, Namibia, and South Africa, encroaching into parts of Angola, Zambia and Zimbabwe.
Mapping of the distribution and extent of natural vegetation of South Africa started in 1918 when the Botanical Survey of the Union of South Africa was established.

This West African nation has a long Atlantic coastline and a range of habitat types, with a corresponding diversity of plants and animals. Liberia is considered a biodiversity hotspot and has more intact forests characteristic of the Upper Guinea Massif than do neighbouring countries. There are 2000 species of vascular plants (including 225 ...
Savanna and open woodland are the characteristic vegetation types. Species of Combretum and Terminalia are the typical savanna trees, and the ground is covered with long grasses, herbs, and shrubs.

A few enclaves of montane forest lie further inland in the mountains of central Guinea and central Togo and Benin. [1]
The Guinean forest-savanna, also known as the Guinean forest-savanna transition, is a distinctive ecological region located in West Africa. [2] [3] It stretches across several countries including Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria, and Cameroon. This region is characterized by a unique blend of forested ...
