Grasslands first appeared millions of years ago due to radical changes in climate and have been key to human survival for at least 10,000 years, by offering pasture for livestock and fields for crops.
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. [1] 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 ...

These grasslands can be classified as the tropical and subtropical grasslands, savannas and shrublands biome. The rainfall level for that grassland type is between 90 and 150 centimeters per year. Grasses and scattered trees are common for that ecoregion, as well as large mammals, such as wildebeest (Connochaetes taurinus) and zebra (Equus zebra).
The savannas of northern Australia, sub-Saharan Africa, Asia and South America are examples of tropical grasslands. The climate is warm with contrasting rainy and dry seasons.
The Mitchell Grass Downs is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in northeastern Australia. It is a mostly treeless grassland, characterised by Mitchell grasses ( Astrebla spp.).
25-50% of the rainfall in the Amazon basin comes from the forest, and if deforestation reaches 30-40% most of the Amazon basin will enter a permanent dry climate. [14] In another article published by Nature, it points out that tropical deforestation can lead to large reductions in observed precipitation. [15]
Tropical grasslands, savannas, and shrublands [10] are spread over a large area of the tropics with a vegetation made up mainly of low shrubs and grasses, often including sclerophyll species. [10] Some of the most representative are the Western Zambezian grasslands in Zambia and Angola , as well as the Einasleigh upland savanna in Australia and ...
