Key Points

Natural vegetation refers to a plant community that has grown naturally without human aid and has been left undisturbed for a long time, allowing it to adapt to local climate and soil conditions.

Indian forests are broadly classified into five types based on climate and vegetation: Tropical Evergreen, Tropical Deciduous, Tropical Thorn, Montane, and Littoral and Swamp forests.

These forests are found in warm, humid areas with over 200 cm of annual rainfall, such as the Western Ghats. They are multi-layered and appear green year-round because there is no definite time for trees to shed leaves.

Also known as monsoon forests, these are the most widespread in India, found in regions with 70-200 cm of rainfall. Trees like teak and sal shed their leaves during the dry season to conserve water.

These forests occur in semi-arid areas with less than 50 cm of rainfall, like Rajasthan and Gujarat. The vegetation consists of thorny trees, shrubs, and grasses adapted to dry conditions.

In mountainous regions, vegetation changes with altitude, transitioning from deciduous forests at the foothills to temperate forests (pine, deodar) and finally to Alpine pastures and tundra vegetation at higher elevations.

Found in coastal areas and deltas, these forests consist of salt-tolerant species known as mangroves. The Sunderbans in West Bengal is a significant area for mangrove forests.

The National Forest Policy, last modified in 1988, set a target to bring 33 percent of the country's geographical area under forest cover to maintain environmental stability and ecological balance.

Social forestry is the management of forests and afforestation on barren lands to help with environmental, social, and rural development. It includes urban forestry, rural forestry, and farm forestry.

Major reasons for the decline in wildlife include habitat destruction due to human settlement and agriculture, over-exploitation of forest resources, poaching, and environmental pollution.

Enacted in 1972, this act provides a legal framework for the protection of wild animals, birds, and plants. It established a network of national parks and wildlife sanctuaries to conserve endangered species.

Launched in 1973, Project Tiger is a major conservation program aimed at protecting the tiger population and its habitat in India. It has significantly helped increase the number of tigers.

This project was launched in 1992 to ensure the long-term survival of elephant populations in their natural habitats by protecting their habitats and migration corridors.

A Biosphere Reserve is an area of terrestrial and coastal ecosystems, recognized under UNESCO's Man and Biosphere (MAB) Programme, which promotes solutions for reconciling the conservation of biodiversity with its sustainable use.

India has 18 designated Biosphere Reserves. Among these, twelve are part of the World Network of Biosphere Reserves, recognized by UNESCO for their ecological importance.
