Unveiling a wildlife haven: status and distribution of four Trans-Himalayan ungulates in Sikkim, India

Abstract

AbstractWe conducted surveys in the Trans-Himalayan Tso Lhamo plateau in Sikkim, India, to ascertain the status and distribution of some of India’s last surviving populations of wild ungulates (numbers in brackets are estimates for Sikkim): Tibetan argali Ovis ammon hodgsoni (c. 177 individuals), Tibetan gazelle Procapra picticaudata (c. 77), and kiang Equus kiang polyodon (c. 18). Topography appears to have an important influence on ungulate distribution, and populations of these species are aggregated in a small region along the northern boundary of the plateau. Persistence of the wild ungulates in this area can be attributed to the non-hunting tradition of local residents and to the seasonal absence of livestock (yak Bos grunniens and domestic sheep Ovis aries) and grazing. Nonetheless, wild ungulates remain vulnerable because of their small populations and anthropogenic pressure on their habitats. We recommend that conservation be prioritized in important wildlife habitats through partnerships with local communities.
