INDIA –FOREST AREAS

by
Prof. A. Balasubramanian
Centre for Advanced Studies in Earth Science
University of Mysore,India

Introduction:
The Indian sub-continent has several
geographically significant features.
The physiographic conditions, climate, natural
vegetation and other resources all vary very
widely, in India.
India’s land mass lies within the Latitudes 8
degree 4 minutes to 37 degrees 6 minutes north
and the Longitudes 68 degrees 7 minutes to 97
degrees 2 minutes east.

3

Both, physiographically and biogeographically,
India is one of the most diverse countries, in the
world.
In india, Out of the total land area of 328
Million hectares, almost 142.5 million ha (ie.
About 43.3%) is under agricultural
development and nearly 76.5 million ha (ie.
About 23.27%) is occupied by Forests.
India is one of the 12 mega biodiversity
countries in the world.

4

The Indian forests meet the demand of almost
40% of the energy requirements of the country.
Of this, more than 80% is utilized in rural areas
and about 30% of fodder needs of the cattle
population, are also met out of this.
All Forest products play a very significant role
in the rural and tribal economy.
For landless families and marginal farmers, the
forest related activities often represent the
primary source of income.

5

Understanding of the area under forest is
necessary while studying the geography of
India.
Hence, in this module, the following aspects are
highlighted:
1. FOREST AREA IN INDIA
2. FOREST AREAS CLASSIFIED
3. DISTRIBUTION OF FOREST AREAS
4. STATE-WISE FOREST AREAS
5. MANGROVE AND TREE COVER.

1. FOREST AREA IN INDIA
Forests are both a resource and a habitat.
Forestry is an important part of landuse, and
different types of landuse complement each
other. Landuse planning involves allocating
land for different uses based on land capability
and agro-ecological conditions.
In 2011, the global distribution of forests was
analysed.

7

The observations are:
Rank Country Area in km
2
% of land area
1 Russia 7,762,602 45.40%
2 Brazil 4,776,980 56.10%
3 Canada 3,101,340 31.06%
4 United States 3,030,890 30.84%
5 China 1,821,000 18.21%
6 European Union 1,600,000 35.00%
7 Australia 1,470,832 19.00%
8 Democratic Republic of the Congo 1,219,326 52.00%
9 Argentina 945,336 34.00%
10 Indonesia 884,950 46.46%
11 Venezuela 747,881 82.00%
12 India 778,424 23.68%
13 Mexico 710,000 36.50%

India is the twelfth country in terms of its forest
areas.
Forests in India got evolved over centuries.
The land allocation for forestry has clearly
earmarked the areas set apart as
a. Forestlands, primarily for production of
goods and services and as protected areas,
and

9

b. Non-forestlands where agro forestry, farm
woodlots, wind belts, shelterbelts, avenue
trees, urban parks, homestead forests and
sacred groves could develop.
India’s Forest Conservation Act 1980 is one of
the most progressive forest conservation
legislations in the world. This Act puts severe
restrictions on the diversion of forest land for
non-forestry purposes.

10

The National Forest Policy, 1988 lays out clear
directions and guidelines for forest conservation
and afforestation.
The Recorded Forest Area consists of Reserved
Forests (RF) and Protected Forests (PF) which
have been constituted under the Provisions of
the Indian Forest Act 1927, and also an
additional category as unclassed forests.
The 1995 assessment has shown the following
features:

11

In, 1995, India had
a) 3.5 million ha of forests with more than 70%
of crown density,
b) with 35 million ha with 40-70% crown
density,
c) about 24-93 m ha were under 10-40% crown
cover and
d) 6.08 m ha of land was under scrub area.
The forest cover is classified into 3 canopy
density classes.

12

1. Very Dense Forest (VDF) with canopy
density more than 70%
2. Moderately Dense Forest (MDF) with
Canopy density between 40-70% and
3. Open Forest (OF) with Canopy density
between 10-40%

Scrub which is a degraded forest land with
Canopy density less than 10% is not considered
as a part of forest cover.

13

As per the Forest Report of 2003, the
forest cover in the country was 678
thousand -333 square kilometers. It
constitutes about 20.64% of India’s
geographical area.
Of this, the very dense forest, with canopy
density more than 70%, constitutes 51,285
square kms., which is 1.56% of the total
area.

14

The moderately dense forest with canopy
density between 40 and 70% constitutes
339 thousand -279 square kilometers (sq.
km) which is 10.32% of the total area and
the open forests with canopy density
between 10 and 40 % constitutes 287
thousand -769 square km., about 8.76% of
the total geographical area.

15


2. FOREST AREAS CLASSIFIED
The National Forest Policy of 1952 indicated
the following functional classification:
a) Protected Forests- to be preserved (or)
created for Physical (or) climatic
consideration
b) National Forests-to be maintained and
managed to meet the needs of defense,

16

communication, industry and other general
purposes of public importance.
c) Village Forests to be maintained to provide
fuel wood, small timber, fodder and other
local requirements.
d) Tree lands -area which are outside the
scope of forest management, are essential for
amelioration of physical, environmental and
climatic conditions.

17

The distribution is as follows.
Types of Forest Area in
Million ha
Protection Forests 10
Production Forests 15
Social Forests 25
Protected are Network
(National Parks, Sanctuaries,
etc., )
14
Total 64.0

18


Climatic, rainfall, soil, topography and other
ecological factors influence the vegetation types
of forests. Indian forests show a great variation
and range from tropical to coastal temperate
forest types.
The major forest types of India are
a) Tropical Evergreen Forests
b) Tropical Deciduous Forests
c) Tropical Thorny Forests

19

d) Temperate Forests
e) Alpine Forests
f) Littoral and swamp forests.

The tropical Forests have the mean annual
temperature greater than 24
0
C and the mean
January winter temperature is above 8
0
C
without any frost condition.

20

The subtropical Forests have the mean annual
temperature between 17 and 24
0
C with frost
conditions in January, with 10-18
0
C mean
temperature of winter.
The Temperte forests have 7 to 17
0
C as mean
annual temperature with 1 to 10
0
C in January
containing frost and snow during winter.
The Alpine Forests have less than 7
0
C as mean
annual temperature and < 1
0
C in January with
full of winter snow.

21

These forests are further classified into sixteen
types.
Forest type Area in
(Million ha)
Percentage of
forest Area
1. Tropical dry deciduous forest 29.4 38.2
2. Tropical moist deciduous
forest
23.3 30.3
3. Tropical Thorn forest 5.2 6.7
4. Tropical wet evergreen forest 4.5 5.8
5. Subtropical pine forest 3.7 5.0
6. Sub alpine 3.3 4.3
7. Moist alpine scrub forest 3.3 4.3
8. Alpine forest 3.3 4.3
9. Himalayan moist temperate
forest
2.6 3.4

14. Subtropical dry evergreen
forest
0.2 0.2
15. Himalayan dry temperate
forest
0.2 0.2
16. Tropical dry evergreen forest 0.1 0.1
Total 77.0 100

23

As per Forest survey of India records, of these
16 forest types, tropical dry deciduous forms
the major forest type of India.

Other predominant type is the tropical moist
deciduous forest area.

24


3. DISTRIBUTION OF FOREST AREAS:
India is one of the few countries in the world
which has gone for an operational system of
wall-to wall mapping of forest cover on a
regular cycle of 2 years.
The forest survey of India is the organization
under the ministry of environment and Forests
responsible for monitoring the forests and tree
cover of India.

25

It has been regularly assessing the forest cover
since 1987.

Periodic assessment of forest cover
provides a quantitative measure of the
extent of land area under forest cover
along with canopy density.
A comprehensive assessment of the forest
resources involves measures of numerous
parameters such as forest cover, tree

26

cover, growing stock, species
composition, availability and occurrence
of non-wood forest products and so on.

Based on remote sensing, interpretation of 300
satellite images, detailed ground truth
verification, proper tree cover assessment and
systematic monitoring, the distribution of
forests in India has been snapped with greater
accuracy by the Forest Survey of India.

27

The classification scheme of forest cover
mapping is as follows:
a) Very Dense Forest – All lands with tree
cover of canopy density of 70% and about
b) Moderately Dense Forest- All lands with
tree cover of canopy density between 40%
and 70%
c) Open Forest-All lands with tree cover
canopy density between 10% and 40%

28

d) Scrub- Degraded forest lands with canopy
density less than 10%
e) Non-forest- any area not included in the
above classes.

Considering the high ecological significance,
the Mangrove Forest cover in India has been
separately mapped in the 3 canopy density
classes.

29

Forest Survey of India estimates the forest
cover of the country at 63.73 million ha
constituting 19.39% of the geographic area of
the country.
Out of this area, about 37.74 million ha
(11.48%) is dense forest, 25.50 million ha
(7.76%) open forest and 0.49 million ha
(0.15%) mangroves.

30

Madhya Pradesh accounts for the largest forest
cover of the country i.e. 20.68% followed by
Arunachal Pradesh (10.80%), Orissa (7.38%),
Maharashtra (7.32%) and Andhra Pradesh
(6.94%).
The seven North-Eastern states put together
comprise 25.70% of the total forest area in
India.

31


4. STATE-WISE FOREST AREAS

The total Geographic Area of India is
3.287 million sq.km
Of which the Recorded Forest Area (RFA) is
0.774 million sq.km.
This is about 23.57 %.
The Forest Cover (FC) is 0.678 million
sq.km.

32

This is about 20.64 %.
The Forest + Tree Cover (FTC) put together
is about 0.78 million sq.km. This is
almost 23.68 %.
Their distribution varies from state to
state. Let us see the distribution of
forests in different States and Union
Territories of India.

5. MANGROVE AND TREE COVER

Mangroves, in India, comprise of salt tolerant
plant species. They occur along inter-tidal zones
of rivers and seas. They are extended in the
form of narrow strips or as extensive patches.
These are estuarine habitats occupying the river
deltas of tropical and sub-tropical regions.

68

These are fully sheltered environment. They
contain mostly brackish water influx, estuarine
and deltaic muddy soils, good rainfall (1000
mm-3000mm) and temperature between 26
0
C –
35
0
C.
These are considered as ideal habitats for
luxuriant and rich mangrove plant growth.
Mangroves are significantly different from
other vegetation as they survive in a hostile
environment.

69

They survive in an interface between land and
sea, with marked fluctuations in salinity,
storms and tidal surges.
They exhibit a variety of adaptations in terms of
morphology, anatomy, physiology, seed and
seedlings development, and succession
mechanisms.
Mangrove forests are considered the most
productive and biodiverse wetlands on earth.

70

These provide critical habitat for a diverse
marine and terrestrial flora and fauna.
Mangrove vegetation grow well in brackish
wetlands between land and the sea where other
plants can't grow.
Mangroves are woody, specialized types of
trees, growing along the tropical regions.
These trees can live on the edge, where
rainforests meet the oceans.

71

Mangroves contain the tropical maritime tree or
shrub of the genus Rhizophora.
Mangroves have special aerial roots and salt-
filtering tap roots that enable them to thrive
even in brackish water.
These brackish water are salty, but not as salty
as that of the sea water.
Mangrove vegetation are good in protecting the

flow of water.
There are about 39.3 million acres of mangrove
forests exist in the warm coastlines of tropical
oceans all over the world. More than 10.5
million acres or about 27% of mangrove forests
are found in Southeast Asia itself.

Today, the Mangrove cover in India account for
about 3% of the world’s mangrove vegetation.

in the
coastal States/UTs of the country.
Sundarbans, in West Bengal, accounts for a
little less than half of the total area under
mangroves in India.
The Forest Survey of India is assessing the
mangroves using remote sensing technology
since 1987.

Mangrove cover has been categorized into three
major categories as:
a) very dense (canopy density of more than
70%),
b) moderately dense (canopy density between
40-70%) and
c) open (canopy density between 10-40%).

The State of West Bengal has the maximum
mangrove cover in the country amounting to
2136 sq.km which is 46.39% of mangrove
cover in India.
It is followed by Gujarat, as 991sq.km which is
about 22.55% and Andaman and Nicobar
Islands, is 635 sq.km which is 13.26% of the
country’s total mangrove cover.

Forests have always been of great importance to
human beings.
Today, people depend on forests especially for
their economic value, their environmental
value, and their value for culture and
recreation. The science of forestry is concerned
with increasing and preserving these values by
careful management of available forestland in
any country.
Let us protect the forest areas of India.
