Forest cover and assessment in North East India issues and policies
Indian Institute of Remote Sensing (NRSA)

The northeastern part of India, known for its diverse and most extensive lush forest cover, is sadly one of the major regions facing severe deforestation. Forests of this region are unique structurally and species composition. It is a meeting region of temperate east Himalayan flora, palaeo-arctic flora of Tibetan highland and wet evergreen flora of south-east Asia and Yunnan forming bowl of biodiversity. One of the state of this region viz., Arunachal Pradesh occupies a significant place as a crucible for the evolution of flora in north-east India and for speciation. The Brahmaputra valley sandwitched between eastern Himalaya in the north, Garo/Khasi/Jaintia and Mikir/Cachar/Barail hills ranges in the south; is a meeting ground of the temperate east Himalayan flora and the wet evergreen and wet deciduous floristic elements. The Khasi-Jaintia hills function as a corridor of the south-east Asia floristic elements into the Indian subcontinent through the Arakan arc. The altitudinal variation and rainfall patterns of southwest and northeast monsoon play a significant role in the development of ecological niches in this region of India.
According to an official estimate based on satellite images (survey report of FSI), northeastern region has 1,63,799 km2 of forest, which is about 25% of the total forest cover in the country (Anon., 2000). The management of the forest has suffered in the recent past due to pressure on land, decreasing cycle of shifting cultivation, exploitation of forest for timber and lack of scientific management strategy. The age-old practice of shifting cultivation has been a single factor responsible for the forest and land degradation, thereby changing the landscape extensively. About 0.45 million families in northeastern region annually cultivate 10,000 km2 forests whereas total area affected by ‘jhumming’ is believed to be 44,000 km2 (Singh, 1990). Degraded secondary forests, bamboo thickets and weeds or simply barren land dominate today’s ‘jhumscapes’ (Toky and Ramakrishanan, 1981; Roy and Joshi, 2002).
