Grasslands of the World: The assemblage of plant species in an environment is known as natural vegetation. Grasses, forests and shrubs all come under natural vegetation. For the growth of the plant rainfall and temperature are the main factors.

In the area where a decrease of rainfall is less, the concentration and size of the trees decrease. For example in a cold region, rainfall is less, so the growing season is very short, therefore in cold regions plants present in scattered patches in the form of lichens and mosses.

Grassland is the type of vegetation present. Grassland is the area where grasses ans shrubs are present as natural vegetation. In grassland, tree concentration is less or there are no trees. According to UNESCO grassland is an area which covers herbaceous plants with less than 10% of shrubs and trees.
