An understanding of vegetation change on jhum fallows undergoing recovery following shifting cultivation is vital for developing a rehabilitation strategy for shifting cultivation areas. However, the pattern of vegetation change during the recovery of shifting cultivation fallows is not well-studied. Therefore, the present study was carried out in a subtropical forest ecosystem in the buffer zone of Nokrek Biosphere Reserve in north-eastern India where shifting cultivation is being practiced extensively. The species composition and other plant community attributes were studied in 1-year, 3-year, 6-year and 12-year old shifting cultivation (jhum) fallows and were compared with an undisturbed forest in the adjoining core zone of the Biosphere Reserve. The rate of recovery of various community attributes such as species dominance and diversity, tree species population structure, stratification and life form spectrum was, in general, slow. The young fallows exhibited high dominance and low equitably which slowly progressed towards high equitability as recovery progressed with increasing age of the fallows. The number of species recorded in the 12th year of fallow represented about 86% of the total species in the undisturbed forest. Other community attributes of the forest regrowth on the 12-year old fallow reached up to 70-80% of the values recorded in the undisturbed forest community indicating that there was good recovery of species richness and other community attributes on the 12-year old fallows if there was no disturbance.

This article deals with the issue of North-Eastern India, its current social and economic problems in the context of long-term demonstrations of the ethnic separatism. The main aim of the research implies systematic analysis and identification of key factors and reasons perpetuating separatism in NER as well as resource search which determines Indian strategy in solving this problem. The first part of the article is devoted to separatism peculiarities in the region which remains withdrawn and underexplored in many respects. Apart from this, the author provides a quite detailed analysis of negative mentality of the certain part of NER population which justifiably reproaches New Delhi for “discrimination” and inability to solve many problems of the region. Then the author paid the detailed attention to these problems of NER modern society (ethnic, demographic, economic, transport, social etc.) as well as measures undertaken by the Indian government for its settlement.
