Site description Fambong Lho Wildlife Sanctuary is located in East Sikkim on a mountain range opposite Gangtok, the capital of Sikkim.The highest point of the Sanctuary is the Tinjurey Peak (2,750 m), which is connected by mountainous ridges to Fambong Lho Peak and Ragorathai Peak. The Sanctuary is girdled with a number of growing villages. The word ‘Fambong Lho’ seems to have come from the Lepcha word Hambomloh for the local avocado trees Machilus edulis and M. odoratissima. The Himalayan Zoological Park above Gangtok is adjacent to the Sanctuary, separated by the Rani Khola (river). Both the Fambong Lho and the Gangtok ranges form part of the catchment of the Rani Khola (Anon. 2002) and are contiguous with the Ratey Chu Reserve Forest. The main vegetation of this IBA includes Oak Quercus lamellosa and ‘Katus’ Castanopsis hystrix. Rhododendron arboreum interspersed with Lyonia ovalifolia are seen gregariously on high hills and saddles. The IBA is also home to a large number of wild orchids, mosses, ferns and Lycopodium spp. (Anon. 2002).
