India, the vast and diverse subcontinent, is adorned with a myriad of natural wonders, and among its most enchanting treasures are its diverse and lush forests. These vibrant ecosystems are an integral part of India’s rich biodiversity, housing an astonishing array of flora and fauna that have captivated naturalists, researchers, and adventurers for centuries.
Spanning from the snow-capped peaks of the Himalayas in the north to the sun-kissed coastal regions in the south, and from the arid deserts of the west to the dense jungles of the east, India’s forests form a tapestry of ecological wonder.
India’s forest and tree cover is around 24.56 % of its overall geographical area. The nation’s forests have played a crucial role in shaping India’s cultural heritage, serving as sanctuaries for spiritual contemplation, homes for tribal communities, and inspiration for countless mythologies and folklore.
Definition of forest in India
In India, a clear and uniform national definition of ‘forest’ is currently absent. The responsibility of defining what qualifies as a forest lies with the individual states. This delegation of authority was established by the T.N. Godavarman Thirumulkpad vs the Union of India ruling by the Supreme Court in 1996. According to the court’s decision, the term “forest” should be interpreted based on its ordinary “dictionary definition.” Consequently, this definition applies to all legally acknowledged forests, irrespective of their categorization as reserved, protected, or any other designation.
Classification of Forests in India
The diverse forests in India are categorized into five distinct types, with their classification dependent on various factors such as climate, soil, rainfall, and more. These types of forests are classified based on:
- Annual Rainfall
- Classification as per the Constitution of India
Classification based on Annual rainfall
Tropical Evergreen Forest:
- In the far-flung corners of the Western Ghats, the Eastern Ghats, and the Andaman and Nicobar Islands, one can find the enthralling realms of India’s tropical rainforests. These regions receive copious amounts of rainfall, fostering a dense and evergreen canopy of trees that create a sense of mystery and lushness.
- The Western Ghats, a UNESCO World Heritage Site, is especially renowned for its biological diversity and numerous endemic species of plants and animals. Majestic trees like teak, rosewood, and sandalwood dominate these forests, while rare creatures like the lion-tailed macaque and the Nilgiri langur call these verdant realms home.
Tropical Semi-Evergreen Forests
- Tropical Semi-Evergreen Forests represent a transitional forest type, bridging the gap between tropical wet evergreen and tropical deciduous forests. These ecosystems are characterized by relatively drier conditions compared to tropical wet evergreen forests. They can be found distributed along the Western coast, Assam, the lower slopes of the Eastern Himalayas, Odisha, and Andaman Island.
- In these forests, the average annual rainfall ranges from 200 to 250 cm, supporting a diverse range of plant and animal life. The climate within these habitats remains moderate, with average yearly temperatures varying from 24 to 27 degrees Celsius.
- Dominating vast stretches of central and northern India, the deciduous forests exhibit a unique seasonal character, shedding their leaves during the dry season and bursting into lush greenery with the arrival of monsoon rains. Trees like sal, teak, and bamboo are prevalent, providing habitat and sustenance to an assortment of wildlife, including the magnificent Bengal tiger, Indian elephant, and spotted deer.
- The renowned Bandipur National Park and Kanha National Park are two emblematic examples of these enchanting habitats, offering visitors an opportunity to witness the untamed beauty of Indian wildlife.
- Thorn Forests are prominent in India, primarily found in the northern regions and certain drier areas of the Deccan Plateau. These unique ecosystems experience an annual rainfall of less than 70cm.
- The vegetation within tropical thorn forests is characterized by stunted growth, with Acacia species dominating the landscape, rarely reaching heights of more than 6 meters. The forest community also includes other trees and shrubs Babul, Acacia, Kokko, Khair, Khajuri, Ber, Neem, Khejri, Palas etc.
- This eco-region is home to a variety of captivating wildlife, including wild cat species like the common leopard, caracal, Indian desert cat, jungle cat, and rusty-spotted cat. Additionally, canids such as the grey wolf, golden jackal, desert fox, Indian fox, and striped hyena inhabit these forests.
- Beyond the diversified carnivore species, tropical thorn forests support a rich array of herbivorous animals, adding to the intricate ecological balance and splendor of this unique habitat.
Littoral and Swamp Forests
- Littoral and Swamp Forests flourish abundantly across various regions in India. These unique ecosystems can be predominantly found in Deccan Plateau reservoirs, Gujarat’s saline coast, Rajasthan’s saline coast, the Gulf of Kutch, Eastern Coast Deltas, Kashmir’s lakes and rivers, and the swamps of North East India.
- Swamp forests emerge in areas where inadequate drainage and permanent waterlogging of the soil are caused by the landscape’s topography. The distinct hydrological conditions foster the accumulation of plant debris on the forest floor, gradually leading to the formation of thick peat deposits over time.
- The majority of trees in these forests are evergreen, and during low tides, they display fascinating tangled networks of arching roots that become visible. The mangrove ecosystem, a type of littoral and swamp forest, proves to be exceptionally productive, serving as a vital shelter and nursery for a diverse range of fish species and other wildlife in the vicinity. These unique habitats play a crucial role in supporting and sustaining the rich biodiversity of the coastal regions they inhabit.
- As one ascends the towering heights of the Himalayan range, the landscape transforms into a wonderland of alpine forests. These high-altitude forests, found at elevations between 2,000 to 4,000 meters, exhibit unique adaptability to harsh mountain conditions.
- The forests here are composed of coniferous trees like pine, cedar, and fir, while rhododendrons add a burst of color to the surroundings during the flowering season. Snow leopards, red pandas, and Himalayan monals are among the elusive and captivating creatures that inhabit these remote and challenging terrains.
Types of Forest in India – Based on Administration
|This type of forest is unclassified in Government records.||These forests are managed by the government.||These forests are directly under the Government supervision|

|These types of forest cover nearly 18% of the total forest area in India||These types of forest cover about 29% of the total forest area.||53% of the total forest of the country is under this category.|
Forest Classification in India – Based on Merchantability
In India, forests are classified into two types based on their merchantability, which refers to the suitability of goods for ordinary and intended purposes when sold. These categories are Merchantable Forests and Non-Merchantable Forests.
- Merchantable Forests: These forests play a vital role in the economy as they offer a source of income for local communities and contribute significantly to various industries. The primary value of these forests lies in the timber they provide, which is used in construction, furniture production, and other industries. The trees in merchantable forests are suitable for harvesting and can be readily sold in the market, making them economically valuable resources.
- Non-Merchantable Forests: Unlike merchantable forests, these forest areas do not possess commercial value in terms of timber or other economic benefits. However, they hold immense ecological significance and contribute to various environmental services.
Non-merchantable forests serve as crucial habitats for diverse wildlife species, play a role in regulating water cycles, and help maintain soil fertility. Their ecological value is paramount in promoting biodiversity, supporting natural ecosystems, and maintaining the overall ecological balance.
