Abstract

A globally recognized biodiversity hotspot, the Yumthang Valley in North Sikkim, India, is a rich ecological area within the Eastern Himalayas. Often referred to as the ‘Valley of Flowers’, this valley boasts a surprising array of rare, native, and economically important biological species. Besides a diverse mix of alpine herbs, lichens, mosses, and conifers, the Shingba Rhododendron Sanctuary, an essential conservation area in the valley, hosts over 24 species of rhododendrons. The valley’s wildlife is just as diverse, featuring notable species such as the Tibetan Wolf, Himalayan Monal, and Red Panda. Indigenous communities, such as the Lepcha Bhutia and Sherpa, have historically utilized alpine herbs to treat ailments including fever, respiratory issues, stomach issues, wounds, inflammation, etc. Nonetheless, practices like unsustainable harvesting, uncontrolled tourism, and climate change are serious threats to this rich reservoir of biological resources. This review emphasizes the taxonomic distribution, ethnomedicinal and cultural practices of the flora and fauna found in Yumthang Valley. It also discusses conservation challenges while outlining future strategies for the responsible use and scientific exploration of these biological treasures.
