CONSERVATION OF PLANTS AND ANIMALS.

Our first prime minister JAWARLAL NEHRU said “life would be very dull

and colorless if we did not have these magnificent plants, animals

and birds to look and play with.”

What is deforestation?

Deforestation means clearing of forests and using that land for other purposes.

Causes :

Trees in the forest are cut for some of the purposes mentioned below:

Procuring land for cultivation. Building houses and factories. Making furniture or using wood as fuel.

Some natural causes of deforestation are fires and severe droughts.

SOME PROTECTED AREAS AND THEIR BIODIVERSITY

• NATIONAL PARKS:1.Nagarhole National park near mysore famous for its endemic species of reptiles such as cobras, crocodiles, snakes

• 2. Bandipur national park in mysore known for its elephants and bison reserves.

• Here are some pictures of those parks

Wild life sanctuary:- Coringa Wildlife Sanctuary is part of the estuary of the

River Godavari. It supports a rich growth of mangrove vegetation. The habitat is suitable for a variety of wild and feathered species. Its near Kakinada port along Bay of Bengal .

• BIOSPHERE RESERVE:-

• NILGIRIS are reserves in South India including the places like mudumalai, mukurthi, wyanad, silent valley of kerala and bandipur, nagarhole of mysore. They are known for its tropical and semi ever green, dry and moist deciduous trees.

Deforestation is a major cause which leads to the change in soil properties. Physical properties of the soil get affected by plantation and vegetation. Fewer trees result in more SOIL EROSION Removal of the top layer of the soil exposes the lower, hard and rocky layers. This soil has less humus and is less fertile. Gradually the fertile land gets converted into deserts. It is called desertification. Deforestation also leads to a decrease in the water holding capacity of the soil. The movement of water from the soil surface into the ground (infiltration rate) is reduced. So, there are floods. The other properties of the soil like nutrient content, texture, etc., also change because of deforestationThese are some consequences of deforestation.
