The trees are dense, evergreen and short about 10 to 15 metres high. The common plants of these forests are Casuarina equisetifolia, Borassus, Phoenix, Manilkara littoralis, Callophyllum littoralis, Pandanus, Thespesia, Barringtonia, Pongamia, Cocos nucifera, Spinifex littoreus and a number of twiners and climbers. Mangroves are think and evergreen many species of plants, animals, birds, worms and insects propagate in the Mangrove forest. The governments in many states of India has passed laws for protection of trees, and has meanwhile taken steps to increase the forest areas. They are also the house to a large amount of natural medicines. Some of the strangest and most beautiful plants and animals are found in rain forests. All animals, birds, worms and insects help to propagate the plant.
Strong winds and below 0°C temperature prevail for greater part of the year. . Mangrove forests grow in lands near the coastlines in the subtropical and tropical regions of the world. The dry periods are of short duration. Dense mangrove is the common varieties with roots of the plants submerged under water, Ganga, Mahanadi. These form the food for the second stage consumers like forage fish. This causes water to flow through the turbines, turning the generator to produce electricity.
Forests serve as a home to many species. On the basis of availability of water, these forests are further divided into moist and dry deciduous forests. Andhra, Gangetic plains and in some Himalayan tracts extending from Punjab in west to Assam valley in the east. But in these mangroves, with the constant ebb and flow of tides, such an ideal situation is not possible. The forest trees are not dense, 10 to 15 m in height, and undergrowth is abundant.
Thorny Forests: These are mostly found in the dry areas of the Indian desert and parts of the Deccan Plateau. It also had Archean period rocky sands and clay deposits. Tidal forests one distinguished into the following four types with overlapping constituent species: i Tree mangrove forests ii Low mangrove forests, iii Salt water forests and iv Brackish water forests. The members of family Compositae, Rubiaceae, Acanthaceae and Leguminosae form the undergrowth. Tropical Thorn Forests : These forests are found mainly in those areas where the average annual rainfall is less than 75 cm, with a long dry season.
For this reason all wastes are thrown into the mangroves. Our contention is that this long term development and nonpolluting technology should co-exist! The southern slopes of the Himalaya Mountains have denser forests than the north facing areas. They are characterised by giant and luxuriantly growing intermixed deciduous and evergreen species of trees and shrubs. In order to preserve the wildlife, our government has developed a numbers of zoos, national parks and wildlife sanctuaries. Geographical Distribution of Indian Forests Eastern zone consists of moist, deciduous and wet evergreen forests. At that time, the surface of the Earth was three times hotter than it is today.
Bombay, taken from the Portuguese, became the seat of English rule in 1687. In some areas the evergreen trees are found mixed with deciduous trees. Other important mangrove trees are Garan, Gewa, Hetal, Keya, Keora, Bog la etc. The general climatic conditions should be hot and humid. This is of great economic value, with a potential to be converted into a commercial proposition.
A few people hunt wild animals for pleasure and for commercial purposes. The dry season is long and most of the trees remain leafless during that season. These forests are very dense and composed of tall trees reaching upto the height of about 60 metres. Tropical moist forests: These are further classified into the following types on the basis of relative degree of wetness: i Tropical moist evergreen forests, i Tropical moist semi-evergreen forests, and iii Tropical moist deciduous forests. Tidal or Mangrove forests: Tidal forests grow near the estuaries or the deltas of rivers, swampy margins of Islands and along sea coasts. Thus there is abundant feed for the shrimps and other living organisms. Beach Forests: The beach forests are found all along the sea beaches and river deltas.
Forests are very important and useful to us. It is the precursor in the preparation of Vitamin A which is also full of Beta cartenoid pigments. Migratory birds visit the marshes next to Muthupet between October and December. Tree height is upto 20 m or so but girth is not large. The second biggest land use in the country after farming is forests.
