What is Natural Vegetation?

Natural vegetation is the plant life of a region.

  • Natural vegetation is of three types: forest, grasslands and shrubs.
  • The changes in the type of natural vegetation mainly occur because of the changes in the climate region.  

Forests  

  • Forests are of six types: Tropical Evergreen, Tropical Deciduous, Temperate Evergreen, Temperate Decidous, Mediterranean, Vegetation, and Coniferous forests.  
  • Tropical Evergreen Forests are those which occur in the region near the equator and close to the tropics.  
  • Tropical Decidous Forests are monsoon forests which shed their leaves in the dry season to conserve water.
