Under the grassland you have two basic classifications the first is the Tropical Grassland and Temperate grassland. Grassland is region which is dominated by grasses in contrast to forest where you have huge trees as main vegetation or cultivation there.

Types of Grasslands (Dominated by Grass)

Tropical/Savannahs

Now tropical grasslands are known as Savannahs, some of the common examples of tropical grassland.

  • Llanos – S. America

  • Cerrado – Brazil

  • Pine Savannah – Belize & Honduras

Now tropical savannahs are the grassland which are found in the region from north and south. So that is between the tropic of cancer and in the south you have tropic of Capricorn. So you have tropical grassland which is found in the region between tropic of cancer and tropic of Capricorn mainly found in South America, Brazil and South Central America you have Pine Savannahs, Cerrado and Llanos.

Temperate Grasslands

Presence of temperate grasslands across the globe. Now we will see in which part you have these temperate grasslands are known by what names. Now these are also known as the Murray Darling basin.

Temperate Grasslands are known as different names in different countries:

  • Pampas – S. America

  • Velds – Africa

  • Prairies – N. America

  • Steppes – C. Asia

  • Canterbury Plains – New Zealand

  • Murray – Darling Basin – Australia

Now temperate grasslands are found beyond the tropical of cancer and tropic of Capricorn region that’s between north and south. Now next is Prairies.

Prairies (N. America)

  • Flat, Low Lying, Sea of Grass

  • Latin Word – Priata (Meadow)

  • B/W Rockies in West & Great Lakes in East

  • River – Mississippi (USA) & Saskatchewan (Canada)

  • Home to American Indians (Blackfoot Indians), Apache, Crow, Cree, Pawnee

  • Warm Summer (20 oC), Cold Winters (-20 oC)

  • Moderate Rain, Chinook (Local Wind – Hot Wind in Winter)

Prairies are found in North America in contrast to campus, which are found in South America as we said. North America they are mainly found in the region between Canada and United States and this area you have as the prairies. Now if I talk about east to west extension they are found between Rockies mountain chain which runs towards the west and the five great lakes, we also call them as a HOMES. Huron, Ontario, Superior, Michigan, Erie these are the names of five lakes which are found in eastern part of United States and Canada. Now the prairies are usually flat low lying they are also known as sea of grass. This word is derived from Latin word Priata which means Meadows.

Loaction of Prairies on Map

Loaction of Prairies on Map

  • Treeless – Willow, Alder, Poplar

  • Rain > 50 cm – fertile

  • Maize, Potato, Soyabean, Cotton, Alfa-Alfa

  • Low Rain – Short grass

  • Cattle Rearing - Ranches – Cowboys

  • Bison – American Buffalo

  • Rabbit, Coyote, Gopher, Prairie Dogs

  • Granaries of World – Combine (Sow, Plough & thresh)

  • Dairy Farming

  • Minerals

  • USA – Chicago, Minneapolis, Indianopolis, Kansas, Denver

  • Canada – Edmonton, Calgary, Winnipeg, Saskatoon

The major river that flows here are in United States is Mississippi and in Canada is Saskatchewan. It was also previously home to American Indians which were also known as Blackfoot Indians. Other tribes are Apache, Crow, Cree and Pawnee. Summers can be warm as at and winters can be cold as. The region experiences moderate rainfall, the common local wind that blows here which is kind of hot wind which blows in winter is known as Chinook. This Chinook is a kind of local wind similar to what we call as ‘Loo’ in India. This region the prairies is mainly treeless the major proportion here is grasses, however you have few trees which are Willow, Alder, Poplar that are found here. If the rainfall is more than 50cm in the region it is fertile so you have good cultivation Maize, Potato, Soyabean, Cotton, Alfa-Alfa are the main crops that grow into this region. In the region where the rainfall is less you have short grasses. The major activity here is cattle rearing so cattle farms are known as Ranches and persons who take care of the cattle are known as cowboys .Also this region is known for the American Buffalo, which is bison. Now this bison is under protected status because there has been a lot of hunting of bisons going on the other fauna that exists are Rabbit, Coyote, Gopher, Prairie Dogs. Now these prairies are also known as grain-rees of the world because of very huge amount of wheat production. Here the common machinery used as combined this combined machine has Sowing, Ploughing & threshing activity all in one and you have huge farms so you have extensive farming that is done here by means of trackters. Other common farming is dairy farming, minerals are also extracted to smaller extent, common cities that fall under the prairies region in the United States are Chicago, Minneapolis, Indianopolis, Kansas, Denver and Canada you have Edmonton, Calgary, Winnipeg, Saskatoon. Now moving on to the next that is velds.
