Grasslands are dominated by grasses and other herbaceous plants. Savannas are grasslands with scattered trees. Shrublands are dominated by woody or herbaceous shrubs.. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover.
Tropical savanna climates often feature tree-studded grasslands due to its dryness, rather than thick jungle. It is this widespread occurrence of tall, coarse grass (called savanna) which has led to Aw and As climates often being referred to as the tropical savanna. However, there is some doubt whether tropical grasslands are climatically induced.
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.
Aw/As—Tropical savanna climate. (note: Af in light green is Tropical rainforest ) Seasonal tropical forest , also known as moist deciduous , semi-evergreen seasonal , tropical mixed or monsoon [ 1 ] forest, typically contains a range of tree species: only some of which drop some or all of their leaves during the dry season.
There are three basic types of tropical climates within the tropical climate group: tropical rainforest climate (Af), tropical monsoon climate (Am) and tropical savanna or tropical wet and dry climate (Aw for dry winters, and As for dry summers), which are classified and distinguished by the precipitation levels of the driest month in those ...
The Pantanal, with an area of 187,818 km 2 (72,517 sq mi), is the largest flooded grassland on Earth, supporting over 260 species of fish, 700 birds, 90 mammals, 160 reptiles, 45 amphibians, 1,000 butterflies, and 1,600 species of plants. The flooded savannas and grasslands are generally the largest complexes in each region.
Nonetheless, as many as 300 different plant species may grow on less than three acres of North American tallgrass prairie, which also may support more than 3 million individual insects per acre. The Patagonian Steppe and Grasslands are notable for distinctiveness at the generic and familial levels in various taxa. [1]
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.
