Our Natural Resources : Forest and Wildlife From 'TREK' Unit 7 For Class IV

1. Forests and Wildlife

2.  Nature has gifted us
with lots of good
things on which we
depend for our daily
needs.
 We call it NATURAL
RESOURCES.
 Air, Water, Forests,
Soil, Minerals and
Wildlife.

3. Exhaustible
or
Non-Renewable
Resources
Inexhaustible
Or
Renewable
Resources

4. EXHAUSTIBLE OR NON-
RENEWABLE RESOURCES
 Natural resources
which are limited and
which get reduced in
quantity after use are
called exhaustible or
non-renewable
resources.
 Example: Coal,
Petroleum, Natural
Gas, Metals.
INEXHAUSTIBLE OR
RENEWABLE RESOURCES
 Resources which are
available in plenty in
nature and can be
renewed are called
Inexhaustible or
Renewable Resources.
 Examples: Air, Water
and Sunlight.

5. 1. Forest Resources
2. Wildlife Resources

6.  A large area of land thickly covered with
forests.
 Trees and plants give us oxygen.
 The roots of trees prevent soil from being
washed away.
 Improve the quality of soil and make it
more fertile.
 They keep surrounding areas cool.
 There would be no rains and land would
become dry, desert like without forests.

7. •Forests also provide us with food
and fruits.
•They give us timber for making
different products like furniture,
houses, matchsticks and paper.
•Some medicines are made from
the roots, leaves, bark and stems of
some plants.
•We use wood as fuel for cooking.
•Provides shelter to many birds and
animals.

8. 1. Evergreen Forests
2. Deciduous Forests
3. Thorny and Scrub Forests
4. Mountain Forests
5. Tidal Forests

9.  Green throughout the year.
 Dense forest fopund in areas with heavy
rainfall.
 On the eastern slopes of Western Ghats,
the hills of north-eastern India and the
Andaman and Nicobar Islands.
 In these forests one group of trees are
shedding leaves another group of trees
are growing new leaves.
 Trees are tall.
 Ex: Rosewood, Ebony, Bamboo and
Mahogany.

10.  Also called monsoon forests.
 Trees shed leaves every year in the
dry season.
 Ex. : Teak, Sal, Mahua, Semul and
Sandalwood.
 Found in Bihar, MP, Odisha, UP,
Andhra Pradesh, Telangana and
Tamil Nadu.
 Sandalwood is found in Karnataka.

11.  Generally found in the desert areas of
Rajasthan and in dry areas of Gujarat,
Madhya Pradesh, UP, Maharashtra,
Karnataka, Andhra Pradesh, Telangana
and Tamil Nadu.
 Mostly bushes and only a few trees. :
keekar, Babul, and date Palms.
 Long roots, thick bark, sharp thorns and
small leaves.
 Can survive on very little water for many
months.

12.  Found in Himalayan region and in
parts of Nilgiris,
 Between the snowline and about 3000
m above sea level, we find few shrubs.
 As we move lower, we come across
coniferous forests.
 Coniferous – trees are tall and cone
shaped with needle like leaves.
 Ex : Chir, Deodar, Pine and Spruce.

13.  Found in deltas of major rivers.
 Also known as mongroves.
 Dense and treeshave hard wood.
 The Sundari tree is well known which
grows in the Sunderbans, which are
the mangrove forests found in West
Bengal and Bangladesh.

14.  Our forest cover is slowly reducing as trees
are being cut down in large numbers to fulfill
our needs. This is called DEFORESTATION.
 Deforestation leads to soil getting washed
away, to floods and to landslides.
 There is less rainfall and also less oxygen in
the air for us to breathe.
 Many birds and animals loose their homes
when forest is cut down.
 We should make efforts to conserve forests
by planting more trees.
 The Indian Government has launched many
programmes to plant trees.

15.  India has large variety of wildlife.
 Animals are being hunted and killed
in large number for their skin, fur,
horn and tusks.
 To protect wildlife, certain forests are
protected by the government. These
are known as forest reserves or
wildlife sanctuaries.

16.  At present there are 514 wildlife sanctuaries, 39 tiger
reserves, 100 national parks and 21 bird sanctuaries in
India.
 Some famous wildlife sanctuaries are the
 Sunderbans in west Bengal
 Corbett in Uttarakhand
 Kaziranga and Manas in Assam
 Bandipur in Karnataka
 Kanha in Madhya Pradesh
 Periyar in kerala
 Gir in Gujrat
 Sariska , Ranthambore and Keoladeo Ghana in Rajasthan
 Many animals such as lions, tigers, leopards, rhinoceros,
elephants, nilgai, chinkara and monkeys are found in these
sanctuaries.
 Animals live in their natural habitat and no one is allowed to
disturb, hunt or kill them.
