- 1FORESTA forest is a large area dominated by trees.
The trees help create a special environment which, in turn, affects the kinds of animals and plants that can exist in the forest. - 2TYPES OF FORESTThe types of forests in India :
1 .Tropical Evergreen and Semi
Evergreen forests.
2 .Tropical Deciduous Forests. 3.Tropical Thorn Forests.
4 .Montane Forests.
5 .Mangrove Forests. - 3TROPICAL EVERGREEN FORESTThese are also called tropical rain forests. In India such forests are found in very wet regions receiving more than 250 cm average annual rainfall.
- 4FACTS ON TROPICAL EVERGREEN FORESTThese are climatic forests having luxuriantly growing lofty trees which are more than 45 metres in height.
- 5REGIONSThese are found in
1. Andaman and Nicobar.
2.Western coasts and parts of Karnataka. 3.Annamalai hills (Koorj)
4. Assam and Bengal - 6DECIDIOUS FOREST1.These cover an extensive area of the country receiving sufficiently high rainfall (100 to 200 cm) spread over most of the year.
2. The dry periods are of short duration. 3.Many plants of such forests show leaf-fall in hot summer
- 7REGIONSThese forest are found in regions such as Mumbai, N-E. Andhra, Gangetic plains and in some Himalayan tracts extending from Punjab in the west to Assam valley in the east.
- 8TREES FOUNDTrees found in this forest are Teak (Tectona grandis), Terminalia paniculata, T. bellerica, Grewia tilliaefolia, Dalbergia latifolia, Lagerstroemia, Adina cordifolia.
- 9TROPICAL THORN FOREST1.These forests occur in the areas where annual rainfall is between 20 to 70 cm, the dry season is hot and very long.
2. They are found in South Punjab, most of Rajasthan and part of Gujarat.
3.The vegetation in these region occurs only along the rivers.
- 10SPECIES FOUNDThe species of Acacia, Cassia, Calotropis, Randia, Albizzia, Zizyphus, Erythroxylon, Euphorbia, Cordia, and Prosopis are majorly found in this forest.
- 11MONTANE FORESTThese forests are found in the region of fairly high rainfall but where temperature differences between winter and summer are less marked. Winter generally goes without rains.
- 12FACTS ON MONTANE FORESTIn composition, subtropical forests are almost intermediate between tropical forests and temperate forests and a sharp demarcation can seldom be made between tropical and subtropical or subtropical and temperate forests.
- 13MANGROVE FORESTTidal forests grow near the estuaries or the deltas of rivers, swampy margins of Islands and along sea coasts. The soil is formed of silt, silt-loam or silt-clay and sand.
- 14FACTS ON MANGROVE FORESTThe plants are typical halophytes which are characterised by presence of prop roots with well developed knees for support and pneumatophores and viviparous germination of seeds.
