Study Notes

Natural Vegetation in India

Natural vegetation refers to trees and plants growing naturally in a region, determined by climate and soil.
Importance of forests:
- Provide timber for construction and furniture.
- Source of fuelwood, wood pulp, paper, rubber, gums, resins, dyes, and medicines.
- Prevent soil erosion and control floods.
- Supply oxygen to the air and increase rainfall through cooling effects and water vapor release.
- Provide shelter to wildlife and are essential for many tribal communities.

Types of Forests in India

Five main types of forests:
- Evergreen forests: Found in hot, humid areas with abundant rainfall. Trees remain green throughout the year as they don't shed leaves simultaneously. Examples include rosewood, ebony, and mahogany. Found in the Western Ghats and northeastern states (Assam, Arunachal Pradesh, Meghalaya, Tripura).
- Deciduous forests: Found in areas with hot, dry summers followed by heavy rainy seasons. Trees shed leaves during the dry season. Also called monsoon forests. Examples include teak and sal trees. Predominant in the southern plateau and Himalayan foothills.
- Thorn forests: Found in areas with very low rainfall. Short, thorny trees like kikar and babul, and thorny shrubs are common. Needle-like leaves or spines reduce water loss. Predominant in Rajasthan, Gujarat, and parts of the Deccan plateau.
- Mountain forests (Coniferous forests): Found in cold, mountainous regions. Predominant trees are conifers (tall, cone-shaped, with needle-like leaves). Examples include pine, spruce, fir, and oak. Located in the Himalayan region.
- Tidal (Mangrove) Forests: Found in river deltas like Ganga, Mahanadi, and Godavari. Grow in salty, marshy areas that are flooded during high tides. Mangrove trees have roots that grow above ground for breathing. Famous example is the Sundarbans in the Ganga Delta.

Conservation of Forests and Wildlife

Deforestation is a significant problem in India, leading to soil erosion, landslides, floods, and threats to wildlife.
Chipko Movement: A grassroots movement in the hills of Uttarakhand, where villagers embraced trees to prevent their felling in 1974.
Government initiatives for conservation:
- Encouraging tree plantation during Vana Mahotsav.
- Declaring reserved forests where cutting trees and killing wildlife are prohibited.
- Establishing protected areas like wildlife sanctuaries and national parks.
Important protected areas:
- Corbett National Park (Uttarakhand), Kaziranga National Park (Assam), Sundarbans Tiger Reserve (West Bengal), Gir National Park (Gujarat), Kanha National Park (Madhya Pradesh), Periyar Wildlife Sanctuary (Kerala).
