Tropical Grassland

The tropical grasslands are found in the southern hemisphere with moderate rainfall of 20 to 50 inches a year. Grasslands are dominated by grass and other plants. Tropical grasslands include the savanna usually associated with Africa, and savanna-type grasslands found in India, Australia, Nepal and the Americas. They are characterised by drought-resistant shrubs and grasses, dotted with trees such as acacias or baobabs. Seasons here are wet and dry, rather than summer and winter. The plentiful food that springs into life in the wet season draws and supports huge herds of grazing animals, such as the familiar mega-herds of African antelope.Tropical and subtropical grasslands, savannas, and shrublands are a grassland terrestrial biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Grasslands are dominated by grass and other herbaceous plants. Savannas are grasslands with scattered trees. Shrublands are dominated by woody or herbaceous shrubs.


Rainfall in tropical and subtropical grasslands, savannas, and shrublands is between 500 and 1300 millimeters (20 to 50 inches) a year, and can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks.


Tropical and subtropical grasslands, savannas, and shrublands occur on all continents but Antarctica. They are widespread in Africa, and are also found all throughout South Asia, the northern parts of South America and Australia, and the southern United States.


African Savannas occur between forest or woodland regions and grassland regions. The climate varies, with an average temperature of 27 °C with peaks of 30 °C in April and October, and between 300 and 1500 millimetres of rain per year. Flora includes:


-Acacia (Tree)

Loses leaves in dry season to conserve moisture

Leafy canopy in rainy season (flattened by winds)

-Baobab (Tree)

Stores water in trunk

Thick bark to protect it from fires in dry season

Long tap roots to reach underground moisture

Few leaves to reduce water loss through transpiration

-Grass

Grow quickly to 3 or 4 meters in clumps

Shoots die in dry season leaving only roots

-Low shrubs

Drought resistant

Small

Thorns not leaves

Climate

Tropical Grasslands are found in wet and dry climates, it is hot year round and usually never falls under 64 degrees farenheit.
