Natural Vegetation & Forests
Natural Vegetation of India
India possesses diverse natural vegetation ranging from tropical evergreen forests in the Western Ghats to alpine meadows in the Himalayas. India has about 24.62% of its geographical area under forest cover (2021 assessment). The Forest Survey of India conducts biennial assessments. India lies within the Indomalaya ecozone and is one of the 17 mega-biodiverse countries in the world, hosting about 8% of all recorded species.

Determinants of Natural Vegetation
The distribution of natural vegetation in India is determined by several climatic, edaphic (soil-related), and physiographic factors: (1) Rainfall — the single most important factor; areas with >200 cm rainfall support tropical evergreen forests; 100-200 cm supports moist deciduous; 70-100 cm supports dry deciduous; <70 cm supports thorn and scrub vegetation; the dry months (duration and severity) determine whether forests are evergreen or deciduous. (2) Temperature — controls altitudinal zonation in the Himalayas; tropical forests up to 1,000 m, subtropical to 2,000 m, temperate to 3,000 m, alpine above 3,500 m; in peninsular India, temperature variations are less pronounced due to the moderating effect of the sea. (3) Sunlight — the photoperiod (hours of sunlight) affects flowering and growth; longer photoperiod in summer in northern India supports different vegetation from the equatorial regions. (4) Soil — alluvial soils support dense forests; laterite soils (leached, acidic) support specific vegetation; black cotton soils are grasslands before cultivation; sandy soils support thorn vegetation. (5) Topography — windward slopes receive more rain and have denser forests (e.g., western slopes of Western Ghats); leeward slopes are drier (e.g., Deccan Plateau); altitude determines temperature and hence vegetation type. (6) Human interference — extensive deforestation, shifting cultivation (jhum) in NE India, urbanization, and monoculture plantations have drastically altered natural vegetation patterns. The Champion and Seth classification (1968) is the standard Indian forest classification system, identifying 16 major forest types and 221 sub-types based on climate, physiography, and dominant species.
Tropical Evergreen Forests (Tropical Rain Forests)
Found in areas receiving rainfall above 200 cm with a short dry season (less than 2 months). Distribution: Western Ghats (western slopes from Gujarat border to Kanyakumari), Andaman & Nicobar Islands, Upper Assam and Meghalaya, coastal strip of Karnataka and Maharashtra, parts of Tamil Nadu's windward slopes, and Arunachal Pradesh foothills. Trees are tall (45-60 m), with dense multi-layered canopy that prevents sunlight from reaching the ground. Trees do not shed leaves simultaneously (evergreen) due to year-round moisture availability. The forest is characterized by high species diversity — a single hectare may contain 100+ tree species. Commercially less exploited due to dense undergrowth, heterogeneous composition, and difficulty of extraction. Important species: Rosewood (Dalbergia latifolia — highly valued timber), Ebony (Diospyros — black heartwood), Mahogany (Swietenia — introduced, now widespread), Mesua (Ironwood), Rubber tree (Hevea brasiliensis — plantations in Kerala), cinchona (bark yields quinine), and bamboo (various species). The Western Ghats tropical evergreen forests are one of the world's 8 hottest biodiversity hotspots — over 5,000 flowering plant species with about 35% endemism; 179 amphibian species with 80%+ endemism. Silent Valley NP (Kerala) is a pristine example of tropical evergreen forest. Semi-evergreen forests are a transition between evergreen and deciduous, found in less rainy parts of the Western Ghats and NE India; species include Laurel, White cedar, and Hollock. The tropical wet evergreen forests of the Andaman Islands are distinct from mainland forests and include species of Dipterocarpus, Pterocarpus, and Terminalia.
Tropical Moist Deciduous Forests
The most commercially important and ecologically significant forest type in India, found in areas receiving 100-200 cm of rainfall with a distinct dry season of 4-6 months. Trees shed their leaves during the dry season to conserve moisture — the forest canopy opens up, allowing sunlight to reach the forest floor and promote undergrowth. Distribution: along the Shiwaliks (foothills of the Himalayas), eastern slopes of the Western Ghats, northeastern states (Assam, Meghalaya, Tripura, Manipur, Mizoram), Jharkhand, Chhattisgarh, Odisha, and parts of Bihar, West Bengal, and the Eastern Ghats. Two dominant species divide the moist deciduous forests geographically: Teak (Tectona grandis) — the most economically valuable Indian timber species; dominates the moist deciduous forests of central and southern India — Madhya Pradesh, Maharashtra, Karnataka, Kerala, Tamil Nadu; teak is durable, resistant to termites, and highly prized for furniture, shipbuilding, and construction; India's teak forests are the most extensive in the world; teak was heavily logged by the British for railway sleepers, leading to the first forest conservation laws. Sal (Shorea robusta) — dominates the moist deciduous forests of eastern India — Jharkhand, Chhattisgarh, Odisha, eastern MP, and the sub-Himalayan belt from Uttarakhand to Assam; sal is sacred to Hindus and Buddhists (Buddha was born under a sal tree at Lumbini); its timber is hard and durable, used for construction and railway sleepers; sal forests are also called "sal empire" of eastern India. Other important species: sandalwood (Santalum album — Karnataka is the main producer; used for oil and incense), bamboo (India is the second-largest bamboo producer after China; National Bamboo Mission promotes bamboo cultivation), rosewood, mahua (Madhuca indica — flowers used for alcohol and oil by tribal communities), mulberry (for sericulture), and kusum.
Tropical Dry Deciduous Forests
Found in areas receiving 70-100 cm of rainfall with a long dry season (6-8 months). Trees are shorter (12-25 m), less dense, and more widely spaced than moist deciduous forests. Grasslands often intersperse between trees. Distribution: covers the rain-shadow regions of peninsular India — parts of Maharashtra, Karnataka (northern), Telangana, Andhra Pradesh (Rayalaseema), Tamil Nadu (interior), Uttar Pradesh, Bihar, and the drier parts of Madhya Pradesh. This type grades into thorn forest at its drier margin. Important species: teak (stunted compared to moist deciduous), sal (in northern dry deciduous), peepal (Ficus religiosa — sacred tree), neem (Azadirachta indica — medicinal and pest-resistant), palash/flame of the forest (Butea monosperma — bright orange flowers; state flower of Jharkhand; used in Holi celebrations), tendu/kendu (leaves used for bidi wrapping — a major NTFP; Madhya Pradesh and Chhattisgarh are the largest producers), mahua, shisham (Dalbergia sissoo — good timber), and acacia species. Dry deciduous forests have been extensively cleared for agriculture, especially in the Indo-Gangetic Plain and the Deccan. They are significant economically for Non-Timber Forest Products (NTFPs): tendu leaves, sal seeds (used for oil), lac, honey, gum, and medicinal plants. Tribal communities in Jharkhand, Chhattisgarh, and Odisha depend heavily on NTFP collection from these forests. The Forest Rights Act 2006 recognizes their right to collect, process, and sell NTFPs. Together, the moist and dry deciduous forests constitute about 65% of India's total forest cover — making deciduous forests the dominant vegetation type.
Thorn and Scrub Forests
Found in areas receiving less than 70 cm of rainfall — the semi-arid and arid zones of India. Distribution: Rajasthan (Thar Desert region), Gujarat (Kutch, Saurashtra), Punjab (southern), Haryana (southern), western Uttar Pradesh, rain-shadow areas of the Western Ghats (parts of Maharashtra, Karnataka, Tamil Nadu). Trees are scattered, stunted (usually below 10 m), thorny, and have adaptations to conserve water: long tap roots (reaching groundwater 10-20 m deep), thorny/spiny branches (reduced leaves to minimize transpiration), thick bark, and wax-coated or fleshy leaves. The landscape is a mosaic of xerophytic trees, thorny bushes, and open grasslands. Important species: Khejri (Prosopis cineraria — state tree of Rajasthan; provides shade, fodder, and fuel; the Bishnoi community's sacrifice at Khejarli village near Jodhpur in 1730, where 363 Bishnois were killed protecting Khejri trees, is one of India's earliest recorded environmental protection events; Amrita Devi Bishnoi is the most famous martyr). Babool/Kikar (Acacia nilotica — thorny, drought-resistant; used for gum, tanning, and fuel), Ber (Ziziphus mauritiana — wild jujube; edible fruit), Wild date palm (Phoenix sylvestris), Cactus (Opuntia — introduced from the Americas), Euphorbia (milkweed). The Indian Wild Ass Sanctuary in the Little Rann of Kutch and the Desert National Park in Jaisalmer represent the thorn forest ecosystem at its most extreme. The Thar Desert supports a surprising amount of wildlife despite aridity: Great Indian Bustard, chinkara (Indian gazelle), desert fox, blackbuck. The Aravalli range acts as a barrier preventing the Thar Desert from spreading eastward.
Mangrove Forests
Mangrove forests are specialized coastal ecosystems found along sheltered coastlines, river deltas, tidal creeks, and brackish water zones. They are adapted to saline, waterlogged, and anaerobic soil conditions. India has about 4,992 sq km of mangroves (ISFR 2021) — about 0.15% of geographic area. India has the 4th largest mangrove area in the world (after Indonesia, Brazil, and Australia). Sundarbans (West Bengal/Bangladesh) — the largest mangrove area in India (~4,260 sq km on the Indian side) and the world (~10,000 sq km total); named after the Sundari tree (Heritiera fomes); home to the Royal Bengal Tiger adapted to mangrove habitat (the only swimming tiger population); UNESCO WHS; Ramsar site; mangrove species include Sundari, Rhizophora, Avicennia, Sonneratia, and Ceriops; the Sundarbans face threats from rising sea levels (islands like Ghoramara and Lohachara have been submerged), cyclonic storms (Cyclone Amphan in 2020 devastated large areas), and increasing salinity. Other important mangrove areas: Bhitarkanika (Odisha — 2nd largest in India; saltwater crocodile breeding), Pichavaram (Tamil Nadu — 2nd largest mangrove in TN; protected as a forest reserve), Gulf of Kutch (Gujarat — marine national park), Andaman & Nicobar Islands (significant mangrove cover), Godavari-Krishna Delta (AP — Coringa Mangroves), and Maharashtra coast (Thane Creek Flamingo Sanctuary). Mangroves provide critical ecosystem services: coastal protection from cyclones and tsunamis (the Pichavaram mangroves shielded villages during the 2004 tsunami); breeding grounds for fish, prawns, and shellfish (about 75% of commercial fish species depend on mangroves at some life stage); carbon sequestration (blue carbon — mangroves store 3-5 times more carbon per hectare than terrestrial forests); shoreline stabilization. The Mangrove Cell (Maharashtra) and similar state-level initiatives work on mangrove restoration.
Montane Forests — Himalayan Vegetation Zones
The Himalayas display a remarkable vertical zonation of vegetation with altitude, similar to latitudinal change from the equator to the poles: (1) Tropical moist deciduous forests (foothills up to 1,000 m) — sal, teak, bamboo, palms; the Terai region; heavily cleared for agriculture and settlement. (2) Subtropical forests (1,000-2,000 m) — in the western Himalayas: chir pine (Pinus roxburghii) dominates pure stands on sunny south-facing slopes; pine forests are fire-prone due to needle litter; in the eastern Himalayas: broad-leaved evergreen forests with oak, chestnut, magnolia, and laurel prevail (higher rainfall). (3) Temperate forests (1,500-3,000 m) — western Himalayas: deodar (Cedrus deodara — state tree of HP; "deodar" means "timber of the gods"; prized for durability and fragrance), blue pine (Pinus wallichiana), spruce (Picea smithiana), silver fir (Abies pindrow); eastern Himalayas: oak, birch, maple, laurel, and rhododendron (state tree of Uttarakhand; state flower of Nagaland); temperate grasslands called bugyals found in Uttarakhand (used for seasonal grazing). (4) Sub-alpine forests (3,000-3,500 m) — stunted trees of juniper, rhododendron, birch; trees become gnarled and low as altitude increases; the tree line typically occurs at 3,500-3,800 m. (5) Alpine meadows and pastures (3,500-4,500 m) — treeless grasslands with sedges, grasses, and wildflowers; used for seasonal grazing called margs in Kashmir and bugyals in Uttarakhand; alpine flowers bloom briefly during June-September; Valley of Flowers NP is a famous example. (6) Above 4,500 m — permanent snow and tundra vegetation; mosses, lichens, and some hardy grasses in patches; true periglacial conditions. The eastern Himalayas receive more rainfall than the western and consequently have denser, more diverse vegetation at each altitudinal zone.
Western Ghats and Shola-Grassland Ecosystem
The Western Ghats (Sahyadri) support some of India's richest and most diverse vegetation: from tropical evergreen rainforests at the base (windward western slopes) to montane forests and unique shola-grassland complexes at higher elevations. The Western Ghats are a UNESCO World Heritage Site (2012) and one of the world's 8 hottest biodiversity hotspots. The western (windward) slopes of the Ghats receive heavy orographic rainfall (200-500 cm) and support dense tropical evergreen forests (below 800 m) and semi-evergreen forests (800-1,200 m). The eastern (leeward) slopes receive significantly less rainfall and support dry deciduous and scrub vegetation. Shola forests — unique tropical montane evergreen forests found above 1,500 m in the Nilgiris, Anaimalai, Palani, and Cardamom Hills. "Shola" comes from the Tamil "solai" meaning a grove. These are stunted, dense, moss-covered forests found in sheltered valleys and ravines, interspersed with rolling grasslands on exposed hilltops. The shola-grassland mosaic is a climax ecosystem, not a degraded forest — the grasslands are natural and not a result of deforestation. Sholas harbour extremely high endemism: Nilgiri Tahr, Nilgiri Langur, Lion-tailed Macaque, Nilgiri Marten, and numerous plant species found nowhere else. The shola-grassland ecosystem is threatened by the invasion of exotic tree plantations (eucalyptus, wattle, pine) introduced by the British and continued post-independence, which have replaced native grasslands and sholas in many areas. The Neelakurinji (Strobilanthes kunthiana) — a blue flower that blooms once every 12 years in the Western Ghats shola-grassland zone — last bloomed in 2018 and will bloom again in 2030.
Grasslands and Savanna Ecosystems
India's grasslands are often overlooked in conservation priorities but support unique wildlife. Types: (1) Tropical grasslands/savannas — interspersed with dry deciduous forests in peninsular India; support blackbuck, chinkara, nilgai, Great Indian Bustard, and Indian wolf; the Banni grassland in Gujarat (largest tropical grassland in India, ~3,847 sq km in Kutch district) supports the Banni buffalo breed and is an Important Bird Area. (2) Semi-arid grasslands — found in Rajasthan, Gujarat, and Maharashtra; the Great Indian Bustard habitat (now critically endangered with ~150 birds); the Indian wolf (distinct from the grey wolf, with ~3,000 remaining) depends on open grasslands. (3) Temperate grasslands — bugyals in Uttarakhand and margs in Kashmir at 3,000-4,000 m; used for seasonal grazing by pastoralists (Gujjars, Bakarwals, Van Gujjars). (4) High-altitude meadows — above 4,000 m in Ladakh and Sikkim; support blue sheep (bharal), snow leopard, and Tibetan wild ass (kiang). Indian grasslands have been systematically undervalued: classified as "wastelands" by revenue records, they have been targeted for afforestation, solar parks, and other developmental activities. The 2020 Supreme Court order on Great Indian Bustard habitat protection highlighted the need to conserve grasslands. India has no dedicated grassland conservation policy, unlike its forest policies. The Grasslands of Central India project and similar initiatives by WWF-India and state governments are beginning to address this gap. The Indian Grassland and Fodder Research Institute (Jhansi) works on grassland improvement for livestock.
Forest Survey of India (FSI) and State of Forest Reports
The Forest Survey of India (FSI), established in 1981 in Dehradun, is the nodal agency for monitoring India's forest cover using remote sensing technology. It publishes the India State of Forest Report (ISFR) biennially. The ISFR 2021 (latest available) reports: Total forest cover: 7,13,789 sq km (21.71% of geographic area); Very Dense Forest (canopy >70%): 99,779 sq km; Moderately Dense Forest (40-70%): 3,06,890 sq km; Open Forest (10-40%): 3,07,120 sq km; Tree cover outside forests: 95,748 sq km; Total forest + tree cover: 80.9 million hectares (24.62%). State-wise leaders by absolute area: Madhya Pradesh (77,482 sq km), Arunachal Pradesh (66,688 sq km), Chhattisgarh (55,547 sq km), Odisha (51,619 sq km), Maharashtra (50,778 sq km). By percentage: Mizoram (84.53%), Arunachal Pradesh (79.33%), Meghalaya (76.33%), Manipur (74.34%), Nagaland (73.90%). States/UTs that have gained forest cover (2019-2021): Andhra Pradesh (+647 sq km), Telangana (+632 sq km), Odisha (+537 sq km). States that have lost forest cover: Arunachal Pradesh (-257 sq km), Manipur (-249 sq km), Meghalaya (-73 sq km) — largely due to shifting cultivation. The northeast region accounts for 7.98% of India's geographic area but 23.75% of its forest cover. Mangrove cover: 4,992 sq km — an increase of 17 sq km from the previous assessment. Bamboo bearing area: 1,49,443 sq km. India's recorded forest area (legally designated as forest) is 7,67,419 sq km (23.34% of area) — this differs from actual forest cover because some recorded forests have lost cover while some non-forest areas have tree cover.
Forest Policy and Legislation — Historical Evolution
India's forest governance has evolved significantly from colonial exploitation to conservation-centered management: British Period — Forests were primarily viewed as a source of revenue and raw materials. The Indian Forest Act 1865 was the first forest law; the Indian Forest Act 1927 (still in force with amendments) classified forests into: Reserved Forests (most restricted, highest protection — no entry without permission; about 55% of India's forest area), Protected Forests (people can collect forest produce unless specifically prohibited; about 29%), and Village Forests (managed by village communities for local use). The British established the Dehradun Forest Research Institute (FRI, 1906) — one of the oldest forestry institutes globally. Post-Independence — The National Forest Policy 1952 emphasized protection and maintained the colonial classification. The Forest Conservation Act 1980 was a landmark — it requires prior approval of the Central Government for diversion of forest land to any non-forest purpose (mining, industry, dams, highways); has been effective in reducing large-scale forest clearance; the Advisory Committee of the MoEFCC reviews proposals. The National Forest Policy 1988 marked a paradigm shift — from revenue orientation to ecology, environmental stability, and meeting basic needs of forest-dependent communities; set the 33% target; introduced Joint Forest Management (JFM). The Forest Rights Act 2006 (FRA/Scheduled Tribes and Other Traditional Forest Dwellers Act) — recognized individual forest rights (land titles for tribals occupying forest land before 2005), community forest resource (CFR) rights (right to manage community forest resources), and the right to collect, use, and sell Minor Forest Products. FRA has been controversial: conservationists worry it may weaken forest protection; tribal activists argue it corrects "historical injustice" of forced displacement. By 2023, about 50 lakh individual titles and 90,000+ community forest rights have been granted.
Afforestation, Social Forestry, and Agroforestry
India runs several programmes to increase forest/tree cover: Compensatory Afforestation Fund Management and Planning Authority (CAMPA) — established by the CAMPA Act 2016; when forest land is diverted for non-forest use (e.g., mining, dam), the user must pay compensatory afforestation charges; these funds (~54,000 crore accumulated) are used for afforestation, forest management, and wildlife protection; distributed 90% to states, 10% to the Centre. Green India Mission — one of the 8 missions under the National Action Plan on Climate Change (2008); aims to increase forest/tree cover on 5 million hectares and improve quality on another 5 million hectares by 2030. National Afforestation Programme (NAP) — promotes afforestation through Forest Development Agencies (FDAs) at the division level. Social Forestry and Farm Forestry — involve planting trees on common lands, along roads, canals, and on private farmlands; significant in states like Gujarat, Haryana, and Maharashtra. National Agroforestry Policy (2014) — India was the first country to adopt a national agroforestry policy; promotes integration of trees with agriculture for economic and environmental benefits. Sub-Mission on Agroforestry (SMAF) — provides subsidies to farmers for planting trees on farmlands; emphasizes species like bamboo, timber, and fruit trees. Nagar Van (Urban Forest) Scheme — aims to develop 200 urban forests in cities across India. National Bamboo Mission (restructured 2018) — promotes bamboo cultivation and industry; India has ~13.96 million hectares under bamboo (2nd largest bamboo bearing area globally after China). Joint Forest Management (JFM) — a community-based approach where local communities protect forests and share benefits (timber, NTFPs); about 1.18 lakh JFM committees manage 28+ million hectares; success varies by state (best in West Bengal, Odisha, AP).
Shifting Cultivation, Deforestation, and Forest Degradation
Shifting cultivation (Jhum/Slash-and-burn) — practiced by tribal communities across northeast India (Mizoram, Nagaland, Manipur, Meghalaya, Arunachal Pradesh), parts of Odisha, Andhra Pradesh, Chhattisgarh, and Jharkhand. Known by different names: Jhum (NE India), Podu (AP/Odisha), Bewar/Dahiya (MP/Chhattisgarh), Kumari (Western Ghats), Penda (Andhra Pradesh). Process: forest patches are cleared by cutting and burning, cultivated for 1-3 years (growing rice, millets, vegetables), then abandoned when soil fertility declines; the community moves to a new patch; the abandoned land regenerates over a fallow period (traditionally 15-25 years). The fallow period has shortened (now 3-5 years in many areas) due to population pressure and restricted land access, reducing the land's ability to regenerate — this is the primary cause of forest degradation in NE India. About 2.7 million families practice jhum across 4.1 million hectares in NE India. Alternatives: the North Eastern Region Community Resource Management Project (NERCORMP), the Mission for Integrated Development of Horticulture (MIDH), and sedentary agriculture promotion are being tried. Deforestation drivers in India: expansion of agriculture, infrastructure development (roads, railways, dams), mining, urbanization, forest fires, encroachment, and illegal logging. India lost about 3.5 million hectares of tree cover between 2001-2021 (Global Forest Watch data). However, India has also gained tree cover through plantations, making the net change less dramatic. The compensatory afforestation mechanism has been criticized: monoculture plantations (eucalyptus, teak) on degraded land do not compensate for the loss of old-growth natural forests in terms of biodiversity and ecological function.
Biodiversity Hotspots and Endemism in Indian Vegetation
India has 4 of the world's 36 biodiversity hotspots (areas with exceptional concentrations of endemic species facing exceptional loss of habitat): (1) Western Ghats — extends from Gujarat border to Kanyakumari; one of the "hottest hotspots" globally; over 5,000 flowering plant species (~1,700 endemic); 508 bird species, 179 amphibians (80% endemic), 157 reptiles (~62% endemic); flagship species: Lion-tailed Macaque, Nilgiri Tahr, Malabar Civet, Purple Frog (discovered only in 2003); key threats: coffee/tea/cardamom plantations replacing natural forest, dam construction, mining (iron ore in Goa/Karnataka). (2) Eastern Himalayas — covers NE India (Assam, Meghalaya, Nagaland, Manipur, Mizoram, Tripura, Arunachal Pradesh), Sikkim, and parts of West Bengal; extraordinary orchid diversity (over 800 species), rhododendrons (over 30 species), primitive plants like Gnetum; Red Panda, Hoolock Gibbon, clouded leopard; threats: shifting cultivation, logging, dam construction. (3) Indo-Burma — overlaps with NE India, extending to Myanmar, Thailand, Vietnam, Cambodia, Laos, and southern China; freshwater diversity is exceptional; threats: dam construction, deforestation. (4) Sundaland — represented in India by the Nicobar Islands; characterized by Malesian flora distinct from mainland India; Nicobar megapode, Nicobar pigeon, leatherback turtle nesting; threatened by the 2004 tsunami aftermath and development. India is one of the 17 mega-biodiverse countries, hosting about 8% of the world's species: ~49,000 plant species (~12,000 endemic), ~1,00,693 animal species (~7,000+ endemic), 1,350 bird species (5th highest globally), 3,500+ fish species.
Non-Timber Forest Products (NTFPs) and Forest-Based Livelihoods
About 300 million people in India are directly dependent on forests for their livelihoods, and NTFPs are the primary source of income for about 100 million tribal and forest-dwelling people. Major NTFPs: Tendu/Kendu leaves (Diospyros melanoxylon) — used for wrapping bidis (Indian cigarettes); MP, Chhattisgarh, Odisha, Maharashtra, and AP are major producers; the NTFP trade in tendu leaves alone is worth ~3,000 crore annually; state governments nationalized tendu leaf trade to ensure fair prices for collectors. Sal seeds (Shorea robusta) — oil extracted for cooking and cosmetics; Jharkhand, Chhattisgarh, Odisha. Lac — India produces 50-60% of the world's lac (resinous substance secreted by lac insects on host trees like palash and ber); Jharkhand and Chhattisgarh are the largest producers; used in shellac, lacquer, food coatings. Mahua flowers (Madhuca indica) — fermented for alcohol (country liquor); oil from seeds used for cooking and cosmetics; dried flowers are a food substitute during lean seasons; central and eastern India. Bamboo — construction, furniture, food (bamboo shoots), paper pulp; NE India and Western Ghats. Honey — Khadi and Village Industries Commission (KVIC) promotes forest honey collection. Medicinal plants — India has ~8,000 medicinal plant species; Ashwagandha (MP), Sarpagandha (Rauvolfia serpentina — for hypertension), Neem, Tulsi, Amla, Turmeric, and hundreds more; the National Medicinal Plants Board promotes cultivation and conservation. The Minimum Support Price (MSP) for Minor Forest Produce was introduced by the Ministry of Tribal Affairs under the mechanism for marketing of MFP through MSP, covering items like sal seeds, lac, tamarind, gum karaya, mahua, and tendu leaves. The Van Dhan Scheme (2018) — promotes value addition of MFPs by tribal communities through Van Dhan Vikas Kendras.
Climate Change Impact on Indian Forests
Climate change poses a significant and growing threat to India's natural vegetation: (1) Temperature rise — the Indian Himalayas are warming faster than the global average; the tree line is expected to shift upward by 100-200 m per degree Celsius of warming, squeezing alpine ecosystems; species like the Himalayan musk deer, snow leopard, and Himalayan brown bear are losing habitat. (2) Altered rainfall patterns — changes in monsoon timing and intensity affect forest hydrology; prolonged dry spells increase fire risk; some models predict a 20-30% decline in sal forests by 2100. (3) Forest fires — increasing in frequency and intensity due to warmer, drier conditions; in 2024, Uttarakhand alone recorded over 1,600 fire incidents; pine forests (chir pine needle litter is highly flammable) are most vulnerable; FSI recorded 2.46 lakh fire alerts in India in 2021. (4) Sea level rise — threatens mangrove ecosystems; the Sundarbans are particularly vulnerable — several islands have already been submerged (Lohachara, Ghoramara); saline water ingress into freshwater wetlands affects vegetation. (5) Species migration — plants and animals are shifting their ranges upward and northward; invasive species may benefit from warming conditions, outcompeting native vegetation. (6) Phenological changes — earlier flowering, altered fruiting seasons, and mismatches between plants and their pollinators/seed dispersers. India's National Mission for a Green India (GIM) and the Green Credit Programme aim to address climate change through increased carbon sequestration in forests. India's forests are estimated to be a net carbon sink of 330.7 million tonnes CO2 equivalent per year (BUR-3 to UNFCCC). The Nationally Determined Contribution (NDC) under the Paris Agreement includes creating an additional carbon sink of 2.5-3 billion tonnes CO2 equivalent through additional forest and tree cover by 2030.
Relevant Exams
Natural vegetation and forest types are essential for both geography and environment sections. UPSC asks about forest types, their distribution, and species-region associations. SSC exams test factual recall — largest mangrove, state with highest forest percentage, and tree species. Current affairs questions on ISFR reports, FRA, and afforestation schemes are also common.
