A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.
Even under the hot conditions of the Kalahari Desert, many species survive; in fact the country has more than 2500 species of plants and 650 species of trees. [2] Vegetation and its wild fruits are also extremely important to rural populations living in the desert and are the principal source of food, fuel and medicine for many inhabitants.
In terms of plant life, it contains a mix of tree species such as mahogany, iroko, and various species of acacia, alongside grasses and shrubs common to savannas. The region is mainly grassland crossed with trees growing alongside streams and on hillsides, with the constantly occurring fires keeping back the growth of trees in open country. [4]

The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between 90–150 centimetres (35–59 in) per year. [1] Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions.
These monuments will play a vital role in saving hundreds of plants and animals, many of them unique to these landscapes, like the iconic Joshua Tree, desert bighorn sheep and pronghorn antelope ...
