A tree savanna at Tarangire National Park in Tanzania in East Africa A grass savanna at Kruger National Park in South Africa. 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.
The Guinean forest–savanna mosaic is known for its high biological diversity. [12] It is home to a wide range of plant and animal species, including many endemic species that are found nowhere else in the world. Some iconic species found here include chimpanzees, pygmy hippos, forest elephants, and various species of primates and birds. They ...
Temperate grasslands, savannas, and shrublands are terrestrial biomes defined by the World Wide Fund for Nature. [1] The predominant vegetation in these biomes consists of grass and/or shrubs. The climate is temperate and ranges from semi-arid to semi-humid. The habitat type differs from tropical grasslands in the annual temperature regime and ...
In the north and east, Mopane savanna with the trees Colophospermum mopane, Sesamothamnus benguellensis, and S. guerichii, is predominant. The semi-desert and savanna transition community supports a variety of species. In the south, open dwarf shrub savanna, with small trees scattered among shrubs, herbs, and grasses, is predominant.

The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Tropical grasslands are mainly found between 5 degrees and 20 degrees in both North and south of the Equator.
Fires set by lightning ensured that the savanna areas did not turn into forests. Savannas normally were found next to large prairies near rolling hills and this combination of habitat was perfect for deer, bison, elk, and other grazing animals. [11] Only trees with a high tolerance for fire, principally certain oak species, were able to survive.
The predominant tree is miombo (Brachystegia spp.). It also provides food and cover for mammals such as the African elephant ( Loxodonta africana ), African wild dog ( Lycaon pictus ), sable antelope ( Hippotragus niger ) and Lichtenstein's hartebeest ( Sigmoceros lichtensteinii ).
The vegetation types found here are northern Sudan savanna, shrub savanna, tree-savanna and gallery forests. The park is home to lion, elephant, buffalo and a number of antelope species. Poaching and deforestation activities are an issue in the park. The main road from Ouagadougou to Bolgatanga in northern Ghana runs across the park. [5] [10]
