Tropical Evergreen Forests
Found in areas receiving heavy annual rainfall of over 200 cm with short dry seasons, featuring dense, multi-layered canopies of tall trees like ebony, mahogany, and rosewood.
Tropical Deciduous Forests
Also known as monsoon forests, these are the most widespread forests in India, shedding their leaves during the dry season to conserve water; they are divided into moist and dry deciduous.
Thorn Forests and Scrubs
Vegetation type found in regions with less than 70 cm of rainfall, characterized by stunted trees, thorny bushes, succulent stems, and deep roots to survive arid conditions.
Montane Forests
Forests that show a successional change in vegetation type with increasing altitude, transitioning from tropical to subtropical, temperate, and finally alpine tundra vegetation in mountainous regions.
Mangrove Forests
Halophytic (salt-tolerant) mangrove vegetation found in coastal areas, estuaries, and deltas influenced by tides, featuring stilt-like breathing roots (pneumatophores).

Frequently Asked Questions
Evergreen forests do not shed all their leaves simultaneously and remain green year-round due to high rainfall, whereas deciduous forests shed their leaves completely during the dry season to conserve moisture.
Mangroves act as a natural barrier protecting coastal areas from severe storms, cyclonic winds, and tsunamis while stabilizing shorelines and serving as breeding grounds for marine life.
Temperature decreases with an increase in altitude (lapse rate), which creates distinct vegetation zones ranging from tropical forests at the foothills to alpine grasslands and mosses near the snowline.
