1. CHAPTER - 7
CONSERVATION OF PLANTS
AND ANIMALS
BY SHIVAM PARMAR
(ENTREPRENEUR & TEACHER)

2. DEFORESTATION
• The clearing of forests
and using the land for
various purposes is
termed as deforestation.
• It is responsible for
survival threat to many
living organisms.

3. CAUSES OF
DEFORESTATION
• Rapid urban
development
• Agriculture related
purposes
• Fuel requirement
• Building industries
• Forest Fire
• Making Furniture

4. CONSEQUENCESOF
DEFORESTATION
• Increase in the temperature and
pollution level.
• Decrease in the ground water
level.
• Decrease in rainfall and fertility
of soil.
• Increase in natural calamities
like floods, droughts, etc.
• Decrease in the water holding
capacity of soil.

5. Deforestation will decrease
number of trees that will
lead to increase in carbon
dioxide level in the
atmosphere. The carbon
dioxide gas traps the heat
rays reflected from earth’s
surface and this will result
in increase in temperature
on earth and it will disturb
the water cycle too and
may reduce rainfall. This
could cause droughts.
• Global Warming

6. DESERTIFICATION
• Deforestationchanges soil
properties. Lesser number of
trees result in more soil
erosion. The removal of top
layer of soil results in a hard
rocky layer which is less
fertile. Eventually, the land is
converted into deserts. Such a
process is known as
desertification.
• Improper irrigation is also
responsible for desertification.

7. CONSERVATION OF
FOREST AND WILDLIFE
• To prevent deforestation and for
the conservation of forests and
wildlife, the government has
implemented many rules and
policies.
• Amongst many steps, areas
called sanctuaries, national
parks and biosphere reserves
have been marked where
activities like cultivation, grazing,
hunting, etc. are prohibited.

8. BIOSPHERE RESERVE
• These are the places for
conservation of wild life,
animals, plants, traditional life
of tribes, etc.
• These are the areas meant for
the conservation of biodiversity.
• The biosphere reserve
conserves the biodiversity and
culture of that particular area.

9. FLORAAND FAUNA
(1) Flora:
• The plants of a particular region or area are termed as its flora.
• Examples of flora include mango, jamun, sunflower, etc.

10. • The animals of a particular region
or area are termed as its fauna.
• Examples of fauna include
deer, parrot, ant, goldfish, eagle,
lion etc.
(2) Fauna:

11. ENDEMIC SPECIES
• These are the species which are
completely confined in a particular area
and not found anywhere else.
• Any animal or plant could be endemic to
an area, a state or a country.
• If any destruction takes place at such
habitats, then it could affect their
population and could also endanger the
entire species existence.

12. ENDEMIC SPECIES • Example of endemic species includes tree
like sal, wild mango, etc. and animals like
bison, Indian giant squirrel, etc. which are
found only in Pachmarhi Biosphere Reserve.

13. WILDLIFE SANCTUARY
• These are the areas reserved for the protection, and giving suitable
living conditions to animals.
• Activities like hunting; poaching, capturing, etc. of animals is prohibited
in these sanctuaries.
• Sanctuaries have given protection to many endangered species like
black buck, white eyed buck, elephant, golden cat, pink headed duck,
gharial, marsh crocodile, python, rhinoceros, etc.
• Indian sanctuaries have unique landscapes - broad level forests,
mountain forests and bush lands in deltas of big rivers.

14. NATIONAL PARK
• These are the reserves
that are large and
diverse that provides
protection to entire
ecosystem.
• They preserve plants,
animals, lands
and historic objects etc.
of that particular area.

15. ENDANGERED SPECIES
• Those animals whose numbers
are gradually decreasing and
might get extinct soon are known
as endangered animals.
• The animals small in size are
more likely to become
endangered than the bigger
animals.
Examples of some endangered
animals are snow leopard, Giant
Panda, whooping crane, etc.

16. ECOSYSTEM
• Ecosystem is a system that comprises of all
the plants, animals and micro-organisms
dwelling in a particular area along with
non-living things like air, water, soil, etc.
• There is an equal importance of each and
every organism whether it may be snakes,
frogs, lizards, bats, etc. for proper
functioning of an ecosystem.

17. RED DATA BOOK
• It is a book which has list of
all the endangered plants
and animals.
• The books for plants, animals
and other species are all
individual.

18. MIGRATION
• It is the seasonal movement of
animals, birds, etc. from one place to
another in search for better climate,
breeding place, food, etc.
• There are many birds that migrate
from one part of the earth to another
due to climatic changes mainly for
breeding purpose. They need suitable
climate for rearing their young ones.

19. RECYCLING OF PAPER
• We need to cut 17 full-grown
trees to make one tonne of paper.
We can easily reuse and recycle
paper. Reducing our consumption
of paper can save trees and also
save water and energy used to
manufacture paper.
• Besides, it can also help in
reducing the use of harmful
chemicals that are used to make
paper.

20. • Reforestation is the opposite of deforestation. Here, we plant new trees to
restock forests that have been destroyed.
• In India, we have the Forest (Conservation) Act which aims to preserve and
conserve natural forests and meet the basic needs of the people living in or
near them.
• Reforestation can happen naturally or can be done artificially. If a deforested
area is left undisturbed for some time, the forests grow again.
