  4. 4. VANISHING FOREST The dimensions of deforestation in India are staggering. The forest cover in the country is estimated at 78.29 million hectare, which is 23.81 per cent of the total geographical area. (dense forest 12.30 per cent; open forest 8.75 per cent; and mangrove 0.14 per cent). According to the State of Forest Report (2011), the dense forest cover has increased by 10,098 sq km since 1997. However, this apparent increase in the forest cover is due to plantation by different agencies. The State of Forest Report does not differentiate between natural forests and plantations. Therefore, these reports fail to deliver accurate information about actual loss of natural forests.
  5. 5.  : Species whose population levels are considered to be normal for their survival, such as cattle, sal , pine, rodents, etc.  : These are species which are in danger of extinction. The survival of such species is difficult if the negative factors that have led to a decline in their population continue to operate. The examples of such species are black buck, crocodile.
  6. 6. These are specie whose population has declined to levels from where it is likely to move into the endangered category in the near future if the negative factors continue t o operate. The examples Of such species are blue sheep, Asiatic elephant Gangetic dolphin, etc.  Species with small population may move into the endangered or vulnerable category if the negative factors affecting them continue to operate. The examples of such species are the Himalayan brown bear, wild Asiatic buffalo, desert fox and hornbill, etc.  : These are species which are only found in some particular areas usually isolated by natural or geographical barriers. Examples of such species are the Andaman teal, Nicobar pigeon, Andamanwild pig, mithun in Arunchal Pradesh.
  7. 7.  : These are species which are not found after searches of known or likely areas where they may occur. A species may be extinct from a local area, region, country, continent or the entire earth. Examples of such species are the Asiatic cheetah, pink head duck
  8. 8. FACTORS THAT CAUSE DEPLETION OF THE FAUNA FLORA AND The greatest damage inflicted on Indian forests was during the colonial period due to the expansion of the railways, agriculture, commercial and scientific forestry and mining activities. Even after Independence, agricultural expansion continues to be one of the major causes of depletion of forest resources. Between 1951 and 1980, according to the Forest Survey of India, over 26,200 sq. km. of forest area was converted into agricultural land all over India
  9. 9. CONSERVATION OF & IN INDIA The Indian Wildlife (Protection) Act was implemented in 1972, with various provisions for protecting habitats.  The thrust of the programme was towards protecting the remaining population of certain endangered species by banning hunting, giving legal protection to their habitats, and restricting trade in wildlife.  Subsequently, central and many state 
  10. 10.  The central government also announced several projects for protecting specific animals, which were gravely threatened, including the tiger, the onehorned rhinoceros, the Kashmir stag or hangul, three types of crocodiles – fresh water crocodile, saltwater crocodile and the Gharial, the Asiatic lion, and others.
  11. 11.     “Project Tiger”, one of the well-publicised wildlife campaigns in the world, was launched in 1973. Initially, it showed success as the tiger population went up to 4,002 in 1985 and 4,334 in 1989. But in 1993, the population of the tiger had dropped to 3,600. There were 39 tiger reserves in India covering an area of 32137.14 sq km* Tiger conservation has been viewed not only as an effort to save an endangered species, but with equal importance as a means of preserving biotypes of sizeable magnitude. Corbett National Park in Uttarakhand, Sunderbans National Park in West Bengal, Bandhavgarh National Park in Madhya Pradesh, Sariska Wildlife Sanctuary in Rajasthan, Manas Tiger Reserve in Assam and Periyar Tiger Reserve in Kerala are some of the tiger reserves of India.
  12. 12. reserved Forests: More than half of the total forest land has been declared reserved forests. Reserved forests are regarded as the most valuable as far as the conservation of forest and wildlife resources are concerned. protected Forests: Almost one-third of the total forest area is protected forest, as declared by the Forest Department. This forest land are protected from any further depletion.
  13. 13. unclassed Forests: These are other forests and wastelands belonging to both government and private individuals and communities.
