deplition of forest

  1. 1. • Human use up the flora and fauna in different ways such as medicines , dyes, , food , fodder ,etc . • The greatest damage inflicted on the indian forests was during the colonial period . One of the most important reasons for this was construction of railways . Ther have been lot of trees cut for the railway tracks which was built in india . • The other reasons also could be agriculture , commercial and scientific forestry and mining activities
  2. 2. 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. Substantial parts of the tribal belts, especially in the northeastern and central India, have been deforested or degraded by shifting cultivation (jhum), a type of „slash and burn‟ agriculture.
  3. 3. Have the colonial forest policies contributed to depletion? Some of our environmental activists say that the promotion of a few favored species, in many parts of India, has been carried through the ironically-termed “enrichment plantation”, in which a single commercially valuable species was extensively planted and other species eliminated. For instance, teak monoculture has damaged the natural forest in South India and Chirr Pine (Pinusroxburghii) plantations in the Himalayashave replaced the Himalayan oak (Querciusspp.) and Rhododendron forests.
  4. 4. Large-scale development projects have also contributed significantly to the loss of forests. Since 1951, over 5,000 sq km of forest was cleared for river valley projects. Clearing of forests is still continuing with projects like the Narmada Sagar Project in Madhya Pradesh, which would inundate 40,000 hectares of forest. Mining is another important factor behind deforestation. The Buxa Tiger Reserve in West Bengal is seriously threatened by the ongoing dolomite mining. It has disturbed the natural habitat of many species and blocked the migration route of several others, including the great Indian elephant.
  5. 5. Himalayan Yew The Himalayan Yew (Taxus wallachiana) is a medicinal plant found in various parts of Himachal Pradesh and Arunachal Pradesh. A chemical compound called „taxol‟ is extracted from the bark, needles, twigs and roots of this tree, and it has been successfully used to treat some cancers – the drug is now the biggest selling anti- cancer drug in the world. The species is under great threat due to over-exploitation. In the last one decade, thousands of yew trees have dried up in various parts of Himachal Pradesh and Arunachal Pradesh.
  6. 6. • Madhya pradesh has the largest area under permanent forests which constitutes 75 % of its total forest area . • Jammu and kashmir , Andhra pradesh, Tamil nadu, Kerala , West bengal , Maharashtra and Uttarakhand have large percentages of reserved forests of its total forest area . • Bihar ,Himachal pradesh , Orissa , Rajasthan , Haryana and Punjab have most of its area under protected forests . • All north eastern states and parts of Gujarat have a very high percentage as unclassed forests which are managed by local communities .
  7. 7. we know that there are different types of species in the world . But due to over exploitation by the humans these species have started depleting . But there are new schemes and programmes arrived to safeguard the flora and fauna of the country . There has been various projects to conserve animal species . The community has also played a vital role in conserving the resources of the country . The chipko movement lays a good example for this . The JFM is also one of the conservation programme involving the community . So we know that conservation of flora and fauna is really important. HOME
