Natural Vegetation
Refers to a plant community that has grown naturally without human aid and has been left undisturbed by humans for a long time, also known as virgin vegetation.
Tropical Evergreen Forests
Found in warm and humid areas with annual rainfall over 200 cm, featuring dense multi-layered vegetation with trees like Rosewood, Mahogany, and Ebony that do not shed their leaves simultaneously.
Tropical Deciduous Forests
Also known as monsoon forests, found in regions receiving 70 to 200 cm of rainfall, where trees shed their leaves during the dry season to conserve water.
Thorny Bushes and Scrubs
Vegetation found in regions with less than 50 cm of rainfall, consisting of acacias, palms, and euphorbias with modified thorny leaves to minimize transpiration.
Social Forestry

What is the difference between natural vegetation and planted forests?
Natural vegetation grows entirely on its own without human intervention, whereas planted forests or afforestation are explicitly grown and managed by humans.
Why do trees in tropical deciduous forests shed their leaves?
Trees shed their leaves during the dry summer season to reduce water loss through transpiration when soil moisture is low.
What are the main objectives of social forestry?
The main objectives are to reduce pressure on traditional forests, supply fuel wood, fodder, and timber to rural communities, and protect agricultural land from soil erosion.
