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 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]
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 classification system uses a hierarchy to organise the vegetation types within the nine defined biomes and a tenth azonal group. Bioregions are described within the biomes, and the vegetation types are at the more detailed level, and represent groups of communities with similar biotic and abiotic features.
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.
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.
Phytoliths (from Greek, "plant stone") are rigid, microscopic mineral deposits found in some plant tissues, often persisting after the decay of the plant.Although some use "phytolith" to refer to all mineral secretions by plants, it more commonly refers to siliceous plant remains.
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 ...
