FORESTS AND WILD LIFE
A large area of land on which trees and other plants grow naturally is called a forest.
Total area of land under forest in India - 23.81 %
Forests are ‘biodiversity hot spots’
Biodiversity measure by – Number of species found there.
- range of different life forms present.
Conservation means- preserve the biodiversity we have inherited
Loss of diversity may lead to loss of ecological stability.

One of the main aim of the management
of forests and wildlife is to conserve the
biodiversity which we have inherited
because the loss of biodiversity leads to
the loss of ecological stability of the
forest ecosystem.
Forests :-
Importance of forests :-
i) Forests help to preserve biodiversity.ii) Forests are natural habitats of plants and animals. iii) Forests provide timber, wood, fuel, medicines, fodder,etc.iv) Forests help to maintain ecological balance.v) Forests help to control climate and rainfall.vi) Forests help to prevent soil erosion and controls floods.vii) Forests help to maintain the oxygen–carbon dioxide balance
in nature.
Forest Department of the Government who owns the forests and controls the resources from the forests.
Industrialists who use the raw materials from forests for manufacturing paper, medicines, furniture etc.
People who are
associated with
forests directly
or indirectly are
People living in
and around
forests depend on
forests for their
livelihood
Nature and wild life organizations who want to conserve and preserve forests.
Stake holders
of forests
The people or tribes
Use resources in such a way that much damage
is not done to the environment
Collect fodder and graze their
forest
Most depended people on
forest.
They usually lop the
branches of the trees and
pluck their leaves but do
not cut the whole treeBamboo ,gather
fruits, nuts and medicinal herbs
The forest department
Destroy large amount of biodiversity due to their
needs
Cut down forest trees for timber for furniture
The development projects like•Building roads
•Construction of damsTo plant trees for timber
Such as pine , teak and eucalyptus
Forests are cleared of all vegetation in a large
scaleDue to which
they
The industrialists go their way…
Have major vested in forest resources.
Forests are the source of raw material for
their industry
Some industries based on forest produce:
•Timber Industry•Paper mills•Lac industry
•Sports equipment industry
Most of the deforestation is caused by industrial
needs.
There are certain people who are not dependent on forest in any way but who
wants forests to be conserved to prevent undue damage to the environment
Bishnoi community in
Rajasthan
The chipko andolan
A group of 363 people
sacrificed their lives
Led by Amrita Devi Bishnoi
Protected the Khejri Trees in Kejrali Village near Jodhpur
The govt. has recently instituted an ‘Amrita Devi
Bishnoi National Award For Wildlife Conservation’ in memory of Amrita Devi
Bishnoi
Reni in Garhwal, High up in the
Himalayas in the early 1970’s
A logging contractor had been allowed to cut down the trees in
a forest close near village.
The villagers reached forest quickly and
clasped the tree trunk with their arms
preventing the workers cutting the trees. Thus the trees were saved.
Two instances showing bravery and love for forest by the local
people nearby forest
Silviculture and it’s advantages
Silviculture is the practice of controlling the establishment,
growth, composition, health, and quality of forests to meet diverse
needs and values.
Produces a large quantity of raw material for industrial purposes Prevents soil erosion
Prevents floods
Increases the area of Earth under
forests
Maintains perfect water cycle in nature
Conservation of forests :-Forests can be conserved by :-
i) Afforestation – planting of more trees.
ii) Preventing or reducing deforestation.
iii) Preventing over grazing by cattle.
iv) By setting up wildlife sanctuaries, national parks, biosphere reserves etc.
v) Undertaking social forestry programs like Van Mahotsav, Chipko
movement for planting and protecting trees on a large scale.
WILDLIFE
The wild animals and birds which live in forest are called wildlife.
Importance of wildlifei) Wildlife helps to preserve biodiversity.
ii) Wildlife helps to maintain food chains and food web.
iii) We get useful products from wildlife like food, medicines, leather, bones, honey, lac etc.
Conservation of wildlifei) Preserving the natural habitats of animals.
ii) Banning poaching of animals.
iii) Protecting endangered species of animals.
iv) Setting up of wildlife sanctuaries, national parks, biosphere
reserves etc.
