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 ...
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.
In many tropical climates, vegetation grow in layers: shrubs under tall trees, bushes under shrubs and grasses under bushes. Tropical plants are rich in resources, including coffee, cocoa and oil palm. [6] [7] Listed below are the types of vegetation unique to each of the three climates that make up the tropical climate biome.
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.
Tropical ecosystems may consist of tropical rainforests, seasonal tropical forests, dry (often deciduous) forests, spiny forests, deserts, savannahs, grasslands and other habitat types. There are often wide areas of biodiversity , and species endemism present, particularly in rainforests and seasonal forests.
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).
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 ...
Over many large tropical areas, the dominant biome (forest, savanna or grassland) can not be predicted only by the climate, as historical events plays also a key role, for example, fire activity. [29] In some areas, indeed, it is possible for there to be multiple stable biomes. [30]
