India is one of the twelve mega biodiversity countries
of the world. With about 47,000 plant species, India
occupies tenth place in the world and fourth in Asia
in plant diversity. 
There are about 15,000 flowering plants in India which
account for 6 percent of the world’s total number of
flowering plants. The country has many non-flowering
plants such as ferns, algae, and fungi. 
India also has 89,000 species of animals as well as a
rich variety of fish in its fresh and marine waters.

It refers to a plant community that has
grown naturally without human aid and has
been left undisturbed by humans for a
long time. This is termed as virgin
vegetation. 
Thus, cultivated crops, and fruits,
orchards are a part of vegetation but not
natural vegetation.
Flora: The term flora is used to denote
plants of a particular region or period.
Fauna: The species of animals are
referred to as fauna.

Natural Vegetation
Tropical Evergreen Forests thrive in regions
with over 200 cm of rainfall and a short dry
season. 
They boast towering trees, often exceeding
60 meters in height. 
These dense forests are rich in hardwood
trees like Ebony, Mahogany, and Rosewood. 
Found in regions such as the Western Ghats,
Assam, West Bengal, Lakshadweep, and Andaman
& Nicobar Islands. 
They host a diverse range of plant species,
complicating commercial exploitation. Common
animals in these forests include elephants,
monkeys, lemurs, and deer.

Tropical Evergreen
Tropical Deciduous Forests, also known as monsoon
forests, are the most prevalent forest type in India,
receiving rainfall between 200 cm and 70 cm. They
undergo leaf shedding for about six to eight weeks
during the dry summer period. These forests are
categorized into Moist Deciduous and Dry Deciduous
based on water availability:
(a) Moist Deciduous:
Found in areas with rainfall between 100 cm to 200
cm.
Trees shed leaves during the dry season.
Common trees include Shisham, Bamboo, Sandalwood,
Khair, and Sal.
Cover vast areas including northeastern states,
Himalayan foothills, Jharkhand, West Orissa,
Chhattisgarh, and the eastern slopes of the Western
Ghats.
