India is brimming with natural resources, so much so that the British referred to it as the “Jewel of the Empire.” With the Tropic of Cancer running through the country, India has the perfect climate for forests, but what types of forests are located in India?
India’s forests are divided into five categories according to the amount of rainfall received and species composition. These forests are Tropical, Montane subtropical, Montane temperate, Subalpine, and Alpine. These five categories are further subdivided to make 16 groups of “Forest Types.”
Over the years, India’s forests have been divided into 202 different types and subtypes within the 16 groups. But what are some examples of these, and what are the characteristic features found in each?

An Overview To The Types Of Forests Found In India
India is a large country situated on the Asian continent. India lies between North 8° 4′ and 37° 6′ latitude, and East 68° 7′ and 97° 25′ longitude.
With such a vast landmass, there is a lot of diversity in climate and geology, which, in turn, gives rise to a large variety of different flora and growth forms.
Some of these forms include forests.
Around 24.6%, approximately 199,482,244 acres, of India is covered in forests; these include Tropical and Temperate Forests.
The five broad categories of forest in India are further subdivided into 16 groups, which include:
- Group 1: Tropical Wet Evergreen Forests
- Group 2: Tropical Semi-Evergreen Forests
- Group 3: Tropical Moist Deciduous Forests
- Group 4: Littoral and Swamp Forests
- Group 5: Tropical Dry Deciduous Forests
- Group 6: Tropical Thorn Forests
- Group 7: Tropical Dry evergreen
- Group 8: Subtropical Broadleaved Forests
- Group 9: Subtropical Pine Forests
- Group 10: Subtropical Dry Evergreen Forests
- Group 11: Montane Wet Temperate Forests
- Group 12: Himalayan Moist Temperate Forests
- Group 13: Himalayan Dry Temperate Forests
- Group 14: Sub Alpine Forests
- Group 15: Moist Alpine Scrub
- Group 16: Dry Alpine Scrub
The Five Types Of Forests Found In India, Characteristics And Examples
Under the five main categories of India’s Forests (Tropical, Montane subtropical, Montane temperate, Subalpine, and Alpine), there occur 16 subtypes or groups.
Each group has specific diagnostic characteristics that distinguish it from others.
These dividers are along with climate variations (rainfall and temperature), species composition, and structure.
Below each of the subgroups is broken down, and diagnostic factors are listed.
Types Of Forests Found In India: Tropical Forests
According to Champion and Seth, tropical forests are divided between “Moist” and “Dry.”
Moist Tropical Forests In India
Of the sixteen forest groups, four are categorized as “Moist Tropical.” These include:
Wet Evergreen Forests In India
Tropical Wet Evergreen Forests (group 1) are characterized by evergreen trees that form a closed canopy.
These forests are similar to tropical rainforests. The trees can reach between 246 and 328 feet and have up to four layers or strata formed between the canopy and the ground.
These forests cover an area of 4 955 451 acres, around 2.61% of the total forested area.
Frequent monsoons help to keep these trees wet and perpetuate the evergreen status.
- Some notable species of tree include:
- Dipterocarpus grandiflorum
- Dipterocarpus costatus
- Shorea assmica (in the north)
- Hopea odorata (in the south)
- Mean annual rainfall
- Greater than 118 inches.

- Location
These forests are in Maharashtra, Karnataka, Tamil Nadu, Kerala, Andaman, West Bengal, Assam, Orissa, and the North Eastern Region.
Semi-Evergreen Forests In India
Tropical Semi-Evergreen Forests (group 2) are characterized by a mixture of deciduous and evergreen species.
The deciduous trees generally form the canopy, while the evergreen trees form the understory. This is a species diverse area that grows quite densely.

These forests account for the second-highest percentage of the total forested area across India.
Canopy trees grow to heights of between 98 and 131 feet. The understory trees are also generally evergreen.
These forests cover an area of 33 465 235 acres, around 17.65% of the total forested area.

Mangroves and other freshwater swamp species are found in these forests.
They also tend to be evergreen forests.
Trees in these forests have also adapted to the tidal flooding and subsequent submerging that occurs.
The largest mangrove forest in the world is the Sundarbans, which is located in India.
