A 1968 Survey, Still Standing
Who Classified India’s Forests
Foresters H.G. Champion and S.K. Seth published “A Revised Survey of the Forest Types of India” in 1968. Their survey revised and expanded Champion’s own earlier 1936 classification, refining it with three more decades of field data.
Champion served as a senior colonial-era forester, and Seth continued that survey work into independent India, giving the classification continuity across two eras. No later Indian classification has replaced this system. It remains the reference framework foresters and examiners use today.
True or False: No later Indian classification has replaced Champion and Seth’s 1968 forest-type system.
Sixteen Types, Six Categories
Sixteen Types, at a Glance
Reading the categories in order traces a genuine climb, from humid lowland forest near sea level up to sparse scrub near the snowline.
| # | Type | Category |
|---|---|---|
| 1 | Tropical Wet Evergreen | Moist Tropical |
| 2 | Tropical Semi-Evergreen | Moist Tropical |
| 3 | Tropical Moist Deciduous | Moist Tropical |
| 4 | Littoral and Swamp | Moist Tropical |
| 5 | Tropical Dry Deciduous | Dry Tropical |
| 6 | Tropical Thorn | Dry Tropical |
| 7 | Tropical Dry Evergreen | Dry Tropical |
| 8 | Subtropical Broad-Leaved Hill | Montane Subtropical |
| 9 | Subtropical Pine | Montane Subtropical |
| 10 | Subtropical Dry Evergreen | Montane Subtropical |
| 11 | Montane Wet Temperate | Montane Temperate |
| 12 | Himalayan Moist Temperate | Montane Temperate |
| 13 | Himalayan Dry Temperate | Montane Temperate |
| 14 | Sub-Alpine | Sub-Alpine |
| 15 | Moist Alpine Scrub | Alpine |
| 16 | Dry Alpine Scrub | Alpine |
The headline numbers: 16 major type groups, about 221 sub-types, under 6 broader categories.
Wet to Dry
The Tropical Forest Types
Tropical Wet Evergreen forest grows in the wettest regions, like the Western Ghats and parts of the Northeast. Tropical Semi-Evergreen sits between that and moist deciduous forest, genuinely mixing both kinds of species. Tropical Moist Deciduous is India’s most widespread tropical type, dominated by sal and teak, shedding leaves only briefly.
True or False: Tropical Moist Deciduous is India’s most widespread tropical forest type.
Littoral and Swamp forest covers coastal and estuarine ground, including mangroves, adapted to tidal, saline, and waterlogged conditions. That rounds out the four Moist Tropical types.
The Dry Tropical category adds three more. Tropical Dry Deciduous occurs in drier interior regions, with a more open canopy and a longer leafless period. Tropical Thorn survives in the driest, most arid zones, like parts of Rajasthan and Gujarat, with thorny, drought-adapted plants. Tropical Dry Evergreen is the rarest of the three, confined to small pockets like parts of the Tamil Nadu coast. Reading all seven types in order traces a genuine drop in moisture, from wet evergreen down to dry evergreen.
Up the Mountain
The Himalayan and Montane Types
The system also covers Himalayan forest types. These genuinely change character as elevation increases. Montane Subtropical splits into three: broad-leaved hill forest and pine forest on drier, more exposed slopes, plus a rarer subtropical dry evergreen type. Montane Temperate adds three more: montane wet temperate, and Himalayan moist and dry temperate forest, split by how much moisture each slope gets.
Higher still, Sub-Alpine forest transitions toward the treeline, and finally splits into Moist and Dry Alpine Scrub, the sparse, stunted vegetation nearest the snowline.
More Than One Factor
What Decides a Forest’s Type
Classification rests on four things together: climate, physiognomy, species composition, and phenology. No single factor decides it alone. Topography, soil, altitude, aspect, and biotic influence, like grazing or fire, all genuinely shape the final type.
Aspect can even flip the type. On a single Himalayan hillside, a sun-facing slope can carry pine forest while a shaded, moister slope nearby carries broad-leaved forest instead.
True or False: Champion and Seth’s classification sorts forests by rainfall alone.
Still the Working Standard
Why This System Still Matters
This system remains the standard reference for Indian forestry. It is used in management plans across states. It appears directly in the UPSC syllabus, and its type names show up regularly across both Prelims and Mains geography questions. The Forest Survey of India’s own biennial State of Forest Report still uses Champion and Seth’s type names.
Later researchers have periodically revisited the original 1968 survey, refining specific sub-types as field data has changed. Even so, the core 16-group, six-category structure has stayed fully intact through every refinement.
Three Real Exam Traps on This Topic
This topic has produced three real UPSC Prelims questions, all from 2015, each built around a genuine trap.
- UPSC CSP 2015 Asked where Tropical Wet Evergreen Forests occur. Answer: Arunachal Pradesh and Mizoram, not Himachal Pradesh, which is too temperate for this forest type. View UPSC CSP 2015 Paper →
- UPSC CSP 2015 Asked which forest type teak dominates. Answer: Tropical Moist Deciduous Forest, not tropical rain forest, thorn scrub forest, or temperate forest with grasslands. View UPSC CSP 2015 Paper →
- UPSC CSP 2015 Asked which Indian region combines mangrove, evergreen, and deciduous forest together. Answer: the Andaman and Nicobar Islands, in distinct zones across the chain. North Coastal Andhra Pradesh, South-West Bengal, and Southern Saurashtra each lack at least one of the three. View UPSC CSP 2015 Question →
A 2025 Update
Forest Cover Is Still Being Tracked (2025)
MoSPI released “Environmental Accounting on Forest 2025” on September 25, 2025, its first dedicated national publication on forest accounting. India’s forest cover grew by 17,444.61 sq km between 2010-11 and 2021-22, reaching 7.15 lakh sq km, or 21.76% of the country’s area.
This accounting draws directly on India State of Forest Report data. That’s the same monitoring system that maps forest cover onto Champion and Seth’s original type groups. The 1968 classification isn’t just a historical exam topic. Officials still use its categories to track and report forest change today.
True or False: India’s forest cover grew between 2010-11 and 2021-22, per MoSPI’s 2025 release.
