Shola Grasslands

Grasslands are not restricted only to low rainfall areas .Certain grassland types form when clearings are made in different forest types.Some are located on the higher,steep hill-slopes with patches of forest that occur along the streams and in depressions.The grasslands are related to repeated fires that do not permit the forest to grow.
The grasses are the major producers of biomass inthese regions .Each grasslland ecosystem has a excessive grazing and are suppressed if the area is over-grazed.Others are destroyed by repeated fires and cannot regenerate.Thus over-used or frequently burnt grasslands are degraded and are poor in plant species diversity.
