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 most intact assemblages currently occur in East African Acacia savannas and Zambezian savannas consisting of mosaics of miombo, mopane, and other habitats. [3] Large-scale migration of tropical savanna herbivores, such as wildebeest ( Connochaetes taurinus ) and zebra ( Equus quagga ), are continuing to decline through habitat alteration ...
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 ...
The principal plant communities include Lake Victoria drier peripheral semi-evergreen Guineo-Congolian rain forest, Lake Victoria transitional rain forest, moist Combretum wooded grassland, dry Combretum wooded grassland, Evergreen and semi-evergreen bushland and thicket, Edaphic wooded grassland on drainage-impeded or seasonally flooded soils, and swamp forest.
The ecoregion is a mosaic of forest, savanna, and grassland. Semi-evergreen rainforest is found along the rivers that drain northwards into the Congo Basin, with open woodland, savanna, and grassland in the uplands. Rainforest flora is typically Guineo-Congolian species, while the woodland, savanna, and grassland species are mostly Zambezian. [3]
The Sudanian savanna or Sudan region is a broad belt of tropical savanna that runs east and west across the African continent, from the Ethiopian Highlands in the east to the Atlantic Ocean in the west. It represents the central bioregion within the broader tropical savanna biome of the Afrotropical realm.
Thus surviving pockets of savanna typically became less like savannas and more like forests or thickets. Many oak savanna plant and animal species became extinct or rare. However, a lack of generalized terminology or documentation in historical records has made it difficult to know about the past state of oak savannas. [1]
The Zambezian and mopane woodlands is a tropical and subtropical grasslands, savannas, and shrublands ecoregion of southeastern Africa.. The ecoregion is characterized by the mopane tree (Colophospermum mopane), and extends across portions of Botswana, Malawi, Mozambique, Namibia, South Africa, Eswatini, Zambia, and Zimbabwe, including the lower basins of the Zambezi and Limpopo rivers.
