Conservation of Rhododendrons in Sikkim Himalaya: An Overview

A review of different conservation aspects of rhododendrons from the Sikkim Himalaya is retraced. Works done in the past and present on the various aspects of the regional rhododendrons vis-à-vis national and global research findings are presented and discussed for its contribution and effect to the understanding of the group. Rhododendrons which are classified as rare, endangered and threatened may be wiped out in near future from the biota, if proper management and conservation initiatives are not taken up. Chronologic primary and derived data on various aspects of regional rhododendrons, viz., species enumeration, species availability and distribution, general usage, identification of anthropogenic pressure, ex situ/ in situ and in vitro conservation initiatives, etc. are highlighted. The role of regional rhododendrons as keystone element in the context of Sikkim Himalaya is also presented for a better understanding of conservational issues at upper temperate and lower alpine region of Sikkim.
