3. INTRODUCTION
Our country India is one of the twelve mega bio-diversity countries of
the world With about 47,000 plant species India occupies tenth place in
the
world and fourth occupies tenth place in the world and fourthin Asia in
plant diversity.
There are about 15,000 flowering plants in India which account for 6 per
cent in the world’s total number of flowering plants.
The country has number of flowering plants. The country has many nonflowering plants such as ferns algae and fungi. India also has
approximately 90,000 species of animals as well as a rich variety of fish
in its fresh and marine waters.
Natural vegetation refers to a plant community which has grown
naturally without human aid and has been left undisturbed by humans
for a long time. This is termed as a virgin vegetation. Thus, cultivated
crops and fruits, orchards form part of vegetation but not natural
vegetation

10. All the plants and animals in an area are interdependent and
interrelated to each other in their physical environment,
thus, forming an ecosystem.
Human beings are also an integral part of the ecosystem.

13. The tropical rainforests are confined to areas of
heavy rainfall. Areas which receive more 200 cm of
rainfall and have a short dry season are the best area
for tropical rainforest. Almost all kinds of vegetation;
like trees, shrubs and creepers; are found in such a
forest. The forest has a multilayered structure.
FLORA- ebony, mahogany, rosewood, rubber and
cinchona
FAUNA- elephants, monkey, lemur, deer and a large
number of birds, bats, sloth, scorpions and snails are
also found in tropical rainforests

15. Tropical deciduous forests are the most widespread forests of
India. They are spread in those regions which get rainfall
between 200 cm and 70 cm. They are also called the
monsoon forests. The trees of tropical deciduous rainforests
shed their leaves during summer. A large part of this region
has been cleared for cultivation and some parts are used for
grazing. These forests can be divided into two types on the
basis of availability of water.
(a) Moist Deciduous Forest: Area which receive rainfall
between 200 cm and 100 cm
(b)Dry Deciduous Forest: Area which receive rainfall between
100 cm and 70 cm
FLORA- Teak, Sal, Peepal, Neem..
FAUNA- Lion, tiger, pig, deer and elephant.

17. Thorn forests grow in those regions which receive
less than 70 cm of rainfall. The trees are scattered
and they have long roots which go very deep in the
ground. The stems are succulent to conserve water.
Leaves are usually modified into thorns to prevent
evaporation.
FLORA- acacia, palms, euphorbias and cactus.
FAUNA- Camel, rats, mice, rabbits, fox, wolf, tiger,
lion, wild ass, horse.

19. Montane Forests
The forests in the mountainous areas are called montane
forest. Different types of vegetation are found at different
altitudes in the mountains. These forests can be divided into
three types:(a)The wet temperate type of forest is found between a height
of 1000 and 2000 metre.
(b)Temperate forests are found between the heights of 1500
and 3000 metre.
(c)Alpine vegetation are found are heights of more than 3600
metre.
FLORA- pine, deodar, oak ,chestnut, silver fir, spruce and
cedar.
FAUNA- Kashmir stag, spotted deer, wild sheep, jack rabbit,
Tibetan antelope, yak, snow leopard, squirrels, Shaggy horn
wild ibex, bear, rare red panda, sheep and goats.

21. Mangrove forests are found in the deltas. Roots of the
mangrove plants are submerged under water. Hollow
roots grow out vertically above water so that roots can
breathe. Sundari tree is the most common tree in such
forests; especially in the Sunderban Delta. Royal
Bengal Tiger is the most famous animal of these
forests
FLORA- Palm, coconut, keora, agar & sundari trees.
FAUNA- tigers ,turtles, crocodiles, gharials turtles and
snakes.
