Plants may attain a height 10-15 metres and form an almost closed evergreen forests. . The supply of wood is projected to increase from 29 million cubic meters in 2000 to 60 million cubic meters in 2020. Commonly found animals are lions, tigers, pigs, deer and elephants. As the Dense Forest is at the foothills of Jankari Mountains, thus the name Jankari Reserve Forest.
Vegetation is sparse in this zone. In 1974, people of Garhwal, under the leadership of Sunderlal Bahuguna, started a movement in which volunteers put their arms around trees marked for felling to stop them from being cut down. Taller trees, called emergent, may rise above the canopy. As a result, the nation has to heavily depend on imports for meeting its growing demand. The trees can grow and survive in fresh as well as in brackish water. Usually found in close proximity to the equator, the region remains temperate and soggy through the 365 days in a year. This gives rise to three distinct zones: a The Tropical Zone, found at an elevation of 500 to 1,600 meters.
Spreading over area of 1,600 sq kms, Bhavnagar Amreli Forest is among the forest having Largest Forest Area. It is estimated that the demand for timber is likely to grow from 58 million cubic metres in 2005 to 153 million cubic meters in 2020. Mountain forests Mountain forests differ significantly along the slopes of the mountain. Bamboos are absent but grasses are common. Forest is the second largest land use in India next to agriculture.
The species of animals are referred to as fauna. Recently there has been a Forest College and a Research institute established in that area. Some forms of wildlife are limited to one of the banks of mighty Brahmaputra River. The trees growing here have long roots and thorns and can live without water for a long time. The average annual temperature should range between 25 °C and 27 °C. The tree, which grows in these areas, is babul, kikar and wild palms. Major species are Oak, Deodar, Fir, Maple and Spruce.
Impacts : Agro-forestry systems can be advantageous over conventional agricultural and forest production methods through increased productivity, economic benefits, social outcomes and the ecological goods and services provided. All these three varieties are characterized by the presence of saline water. Among these forests tidal forest, mangrove forest and swampy forest are important. Dominant tree species found in temperate coniferous forests include cedar, cypress, Douglas fir, pine, spruce and redwood. Financial and technical assistance is provided to many Botanical Gardens by the government since 1992. Some significant trees of dry tropical forest are sal, acacia, mangoes and bamboo. The climate here is characterised by hot, humid summers and dry winters.
Basically, these forests are generated where average annual rainfall ranges varies from 51 cm to 151. The important trees of these forests are rosewood, ebony, mahogany, rubber, cinchona, bamboo, coconut, palms, canes, lianas, etc. Tropical Deciduous Forests : These are the typical monsoon forests and are found mainly in those areas where the average annual rainfall ranges between 70 cm and 200 cm, with mean annual temperature of about 27 °C. It s said that even Lord Krishna have resided in the forests for some time. Some other common associates of shal are Terminalia tomentosa, Dellenia species, Eugenia species, Boswellia species and Mallotus philippensis. These forests produce some of the most important timbers of India.
Temperate Forest : i Wet temperate forest: Mostly occur within eastern Himalaya and peninsular Plateaus. The forest is dense and is filled with a large variety of trees of both types. Forests in India Varied types of forests are found in the Indian subcontinent. These act as respiratory roots under submerged conditions. Trees like chestnut and oaks are predominantly available and these have evergreen and wide leaves.
The average annual relative humidity should be 60 to 75 per cent. Tropical Forest : This type of forest is generally spectacular over the plain region in India. Increasing production of fuels and fodder quality ix. Though it is highly species-rich ecoregion, the diversity is not spread uniformly. Though all of them were hunters and between them and the British they cleaned at least 5000 tigers if not more. Other threats include road construction, clearing land for agriculture and other development activities and climate change.
The relative extents of different types of forests in India are presented in the following Table 11. Winter generally goes without rains. But there are mainly six groups of forest in India which are- moist tropical, dry tropical, montane sub tropical, montane temperate, sub alpine and alpine. Coniferous Forests: These are mostly found on the slopes of the Himalayas. The dry deciduous forests are more open stretches and also have pipal, neem, tendu, bamboo, apart from those in the moist deciduous forests.
