NATURAL VEGETATION
Give two reasons to explain as to why we need to conserve our forest resource?

                    I.     Forest provide many major and minor product like wood, gum, fiber, fruits etc.
                  II.     They play a significant role in the prevention and control of soil erosion.

Mention two condition required for the growth of littoral forest?
·         Forest occur in and around the deltas, estuaries, and creeks prone to tidal forest .trees can survive both fresh as well as brackish water.

State one characteristics feature of the forest found in the nilgiri hills.
·     Nilgiri receives rainfall of 150 to 180 cm so moist deciduous forest dominate the region .trees shed their leaves during the dry season.

Give two reasons to explain as to why the tropical evergreen forest is difficult to exploit for commercial purpose?
·         They are very dense
·         Transport is not possible.

Name two trees found in tropical evergreen forests. = ebony and mahogany

Briefly explain the trees in the tropical desert forest have stunted growth.
·         To minimize loss of water. Lack of water and minerals in the soil.

There is a gradual increase in the forest cover in India in recent times.
·         This is due to promotion of social forestry.

The trees in monsoon deciduous forest shed their leaves for about 6-8 weeks during March and April.
·         Due to longer dry season.

Name the area in India where tropical monsoon forest is found?
Eastern slopes of Western Ghats

How is this forest of great commercial value to India?
These forests provide teak, Sal, sandalwood, which are used for furniture and other wood work.

Why do littoral trees grow aerial roots?
Mangrove can live in the most inundated areas, properly themselves up above the water level with silt roots and can take in air through pores in their barks. Root system allows mangroves to take up gases directly from the atmosphere and various nutrients like iron from the inhospitable soil. Gases are quite often store directly inside the roots and processed even when the roots are submerged during high tide.

Name one area in India where this forest is found == deltas of Ganges, Mahanadi, Godavari, Krishna and Cauvery

Name the state in India where thorn and scrub forest is found.
Punjab plains, northern Madhya Pradesh, south – west Uttar Pradesh, (bundelkhand plateau)

Give two ways by which the trees that are found here have adapted to the climate.
Trees remain small, it saves surface through which water evaporates. Develop an extended root system close to the surface and still collect a lot of water during scanty rainfall.

Give two ways forest are important.
·         They play a significant role in the prevention and control of soil erosion
·         Forest plays an important role in regulating the earth temperature and weather patterns by storing large quantities of carbon and water.


Mention one forest conservation method followed in India.
Social forestry
