H ave you ever been to a forest for a picnic? You might have surely gone to a park if you live in a city or to a mango, guava or coconut orchard, if you live in a village. The National Commission on Agriculture (1976) has classified social forestry into three 47NATURAL VEGETATION categories.

For the purpose of effective conservation of flora and fauna, special steps have been initiated by the Government of India in collaboration with UN ESCO’s ‘Man and Biosphere Programme’. Initially, the Pr oject T iger was launched in nine tiger reserves, covering an area of 16,339 sq. km, which has now increased to 58 tiger reserves, encompassing 84,487 sq.

H ave you ever been to a forest for a picnic? The same variety may be found growing wild in the forest under natural conditions and the same tree may be the planted one in your garden under human supervision. Dry deciduous forest covers vast areas of the country, where rainfall ranges between 70 -100 cm.

Natural vegetation refers to a plant community that has been left undisturbed over a long time, so as to allow its individual species to adjust themselves to climate and soil conditions as fully as possible.

India is a land of great variety of natural vegetation.

Himalayan heights are marked with temperate vegetation; the Western Ghats and the Andaman Nicobar Islands have tropical rain forests, the deltaic regions have tropical forests and mangroves; the desert and semi desert areas of Rajasthan are known for cactii, a wide variety of bushes and thorny vegetation.

Depending upon the variations in the climate and the soil, the vegetation of India changes from one region to another.

On the basis of certain common features such as predominant vegetation type and climatic regions, Indian forests can be divided into the following groups: TYPES OF FORESTS (i) Tropical Evergreen and Semi Evergreen forests (ii) Tropical Deciduous forests (iii) T ropical Thorn forests (iv) Montane forests (v) Littoral and Swamp forests.

Tropical Evergreen and Semi Evergreen Forests These forests are found in the western slope of the Western Ghats, hills of the northeastern region and the Andaman and Nicobar Islands.

They are found in warm and humid areas with an annual precipitation of over 200 cm and mean annual temperature above 22 oC.

Tropical evergreen forests are well stratified, with layers closer to the ground and are covered with shrubs and creepers, with short structured trees followed by tall variety of trees.

In these forests, trees reach great heights up to 60 m or above.

There is no definite time for trees to shed their leaves, flowering and fruition.

As such these forests appear green all the year round.

Species found in these forests include rosewood, mahogony, aini, ebony, etc.

The semi evergreen forests are found in the less rainy parts of these regions.

Such forests have a mixture of evergreen and moist deciduous trees.

The undergrowing climbers provide an evergreen character to these forests.

Main species are white cedar, hollock and kail.

The oak forests in Garhwal and Kumaon were replaced by pine (chirs) which was needed to lay railway lines.

In the higher rainfall regions of the Peninsular plateau and the northern Indian plain, these forests have a parkland landscape with open stretches in which teak and other trees interspersed with patches of grass are common. FOREST CONSERVATION Forests have an intricate interrelationship with life and environment. What steps have been initiated by the government in this direction? For the purpose of effective conservation of flora and fauna, special steps have been initiated by the Government of India in collaboration with UN ESCO’s ‘Man and Biosphere Programme’.

(iii) Pressure on forests mounted due to lopping for fodder and fuelwood and removal of small timber by the local people.
