  • Limited annual rainfall.
  • The dry climate throughout the year.
  • Lack of nutrients in the soil.

  • Poor vegetation growth dominated by grasses.

What are the natural features of grasslands?

Native grasslands are generally defined as areas of native vegetation in which the ground layer is dominated* by native grasses*, with few or no emergent woody species. Despite the usual dominance of native grass species, grasslands can be extremely rich in other herbaceous* plant species.

Tropical grasslands are found mainly in the Sahel south of the Sahara, in East Africa, and in Australia. Temperate grasslands principally occur in North America, Argentina, and across a broad band from Ukraine to China, but in most of these regions they have been substantially altered by agricultural activities.

Why grasslands are not found in Antarctica?
