Tropical grasslands occur on either side of the equator and extend till the tropics. This vegetation grows in the areas of moderate to low amount of rainfall. The grass can grow very tall, about 3 to 4 metres in height. Savannah grasslands of Africa are of this type. Elephants, zebras, giraffes, deer, leopards are common in tropical grasslands.

The features of polar region and types of wildlife are as
(i) They are extremely cold.
(ii) Growth of natural vegetation is very limited here.
(iii) Only mosses, lichens and very small shrubs grow here during short summer.
(iv) Seal, walrus, reindeer, mink (musk oxen), arctic owl, polar bear, snow foxes are some of the common animals found in this region.

Rosewood and mahogany are two hardwood trees found in tropical evergreen forest.

Forest, grassland and shrubs are the three broad categories of natural vegetation.

Temperature and moisture are the factors on which vegetation mostly depend upon.

Grasslands are areas where the vegetation is dominated by grasses and bushes. Grasslands are known by different names in different regions.
Tropical Grasslands
(i) East Africa- Savannah (ii) Brazil- Campos (iii) Venezuela- Llanos
Temperate Grasslands
(i) Argentina- Pampas (ii) North America- Prairie (iii) South Africa- Veld (iv) Central Asia- Steppe (v) Australia- Down

Grasslands are areas where the vegetation is dominated by grasses and bushes.
There are three types of grasslands:
Tropical grasslands: These are occur on either side of the equator and extends till the tropics where moderate to low amount of rainfall receives. The grass can grow very tall, about 3 to 4 metres in height. Savannah grasslands of Africa are of this type. Elephants, zebras, giraffes, deer, leopards are common in tropical grasslands.
Temperate grasslands: These are found in the mid-latitudinal zones and in the interior part of the continents. Grasses are short and nutritious. Wild buffaloes, bisons, antelopes are common in the temperate region.
Thorny bushes: These are found in the dry desert like regions. Tropical deserts are located on the Western margins of the continents.
The vegetation cover is scarce here because of scanty rain and scorching heat. Mosses, lichens and very small shrubs are found here. It grows during the very short summer; hence it is called Tundra type of vegetation.
Tundra Vegetation: This vegetation is found in the polar areas of Europe, Asia and North America. The animals have thick fur and thick skin to protect themselves from the cold climatic conditions.Seal, walruses, musk-oxen, Arctic owl, Polar bear and snow foxes are some of the animals found here.
