Abstract

Present paper is an outcome of a four-year floristic survey work carried out in Upper Siang district of eastern Himalayan region in India which is also recognized as one of the 39 known 'Biodiversity Hot-Spots' of the world. We present here with a vegetation analysis of this area along with a checklist of 1,003 taxa belonging to 110 families, 529 genera, 994 species, 1 subspecies and 8 varieties of the angiosperms. Besides, one new species, 3 new records to India and 82 endemic species were also recorded. The diversity of herbs and shrubs were found higher than the tree species. Orchidaceae was found the most dominant family followed by Poaceae and Fabaceae. Many threatened plants have also been reported from the area. However, rapid urbanization and Jhum cultivation are imposing direct threat to the natural vegetation. We suggest some conservation measures that could help protecting this natural heritage.

이 연구는 세계 39개 생물다양성 hot spot중에 하나인 인도 동부 히말라야 상부 Siang 지역의 식물상을 4년 동안 조사한 결과물이다. 이 지역의 식생에 대한 분석결과와 함께 조사된 총 1,003분류군, 110과, 529속, 994종, 1아종 그리고 8변종의 피자식물 목록을 첨부하였으며 1신종, 3미기록종 및 82특산종을 포함하고 있다. 초본과 관목의 다양성이 교목보다는 높게 나타났으며 과별로는 벼과, 콩과 그리고 난과 순으로 다양성이 우세한 것으로 조사되었다. 이 지역의 절멸위기에 처한 종들을 보고함과 동시에 급속한 도시화와 화전은 자연식생의 직접적인 절멸을 가속화하고 있어 이 지역의 자연유산을 보호하고 보존하는 방법을 찾는데 도움이 되기를 제안한다.
