The document discusses different types of natural vegetation and wildlife found in India. It defines key terms like natural ecosystem, biosphere reserves, and national parks. It also describes some features of different types of forests in India, including thorn forests and tropical deciduous forests. Virgin vegetation is defined as a plant community that has grown naturally without human influence or disturbance over a long period of time. The presentation was created by a 9th grade student as part of a school project.

1. Natural
vegetation
and Wildlife

2. What is natural
ecosystem?
Organism and environment are
closely related with each other.
Life develops only in the suitable
and favorable environment. All the
organisms and the physical
environment of a given region
together form the natural
ecosystem.

3. Define biosphere
reserves.Wildlife in India is very
varied. It is very important to
conserve them.Biosphere
reserves are those forests
where wildlife is protected
and kept in their natural
environment without imposing
any rstriction on their life.

4. Write the names of the
types of vegetation found in
India?
Tropical Rain Forests
Tropical Deciduous Forests
Tropical Thorn Forests
Montane Forests
Mangrove Forests.

5. What is a National
Park?
National Parks are those wild
lands where lands where flora and
fauna are conserved in their
Natural forms. In these parks
every plant and animal species are
protected and preserved totally in
order to hand over them to the
future generations in their vigor
and glory.

6. Describe any three
features of thorn forests.
Areas with an annual rainfall of less
than 70 cm have open stunted forests
and thorny bushes.
Babul, kikar, khair, plums, and Dates
are important species of trees.
These forests have long roots and
sharp thorns. They help them get
moisture from depths. Sharp thorns
protect them from animals.

7. Describe any three features
of Tropical Deciduous
forests.Tropical deciduous forests forms a
natural cover almost all over India,
particularly by between regions of 200
and 75 cm of annual rainfall. Hence
they are called the monsoon forests
par excellence.
They are economically very important
because of timber like sal and teak.
They need care as they are less fire
resistant.

8. What is virgin
vegetation ?
Virgin vegetation refers to a plant
community which has grown naturally
without human aid and has undisturbed
by humans for long time.
This type of vegetation is also termed
as natural vegetation.
Cultivated crops and fruits; orchard
are a part of vegetation but not of
natural vegetation.
