Question

Write an illustrated essay on the various types of natural vegetation along with the details of vegetation and wildlife specific to each area in our country

Answer 1

Forests: A forest is a dense area with a lot of trees, so much that they shade the ground below them. But not all forests are same.

Answer 2

Answer:

Natural vegetation is the total plant life of a particular region that has developed in an environment untouched by man and is the combined result of prevailing climate, soil and biotic conditions. Natural vegetation in India, below a height of about 915 m. above mean sea level, is almost everywhere of the tropical type. Natural vegetation in India has undergone a drastic biotic change.

Changes in soil conditions have given birth to peculiar types of vegetation in many areas. Large areas of forests are depleting every year due to continuous felling and burning of trees for increasing area for cultivation and settlement. Overgrazing has also resulted into depletion of natural vegetation in several areas. Natural vegetation in India is influenced by altitude (in the Himalayan region) and rainfall.

On the basis of altitude, the Himalayan region has all the vegetation varieties found in the tropical to tundra region. The rest of the country has mainly three major vegetation regions, namely tropical wet-evergreen and semi-evergreen forests, the tropical deciduous, and the thorn forests. Wild life species are similarly of a great variety.

It is home to over 91200 species of animals and 45500 species of plants and has four identified hot spots. India is also home to about 7.6% of mammalian species 12.6% of avian species. 6.2% of reptilian species and 6.0% of flowering plants species.

i. Reserved Forests:

Permanently earmarked for production of timber and grazing is seldom allowed.

ii. Protected forests:

These rights are allowed subject to few minor restrictions.

iii. Unclassed forests:

Consists largely of inaccessible forests or unoccupied wastes.

Forests are also classified according to their density, namely: dense, open and mangrove forests.

India’s biological diversity is reflected in the heterogeneity of its forest covers. It is one of the 12 ‘mega-diversity’ countries of the world. India is also at meeting zone of three major bio-geographic realms, namely the Indo-Malayan (the richest in world) the Eurasian and the Afro tropical.
