Abstract

Mountain ungulates are important for alpine ecosystem ecology, yet are understudied, particularly in Asia. Tibetan Argali Ovis ammon hodgsoni occurs across Tibet, with Trans-Himalayan India forming the edge of its distribution. We studied their conservation status in India. We compiled published data and secondary information about the occurrence of argali. We then focused on Ladakh, the remaining stronghold of argali in India. Based on literature from Ladakh and after consulting key-informants, we delimited two major populations of argali and estimate population density and demography using the double-observer method. We found 27 studies on argali in India. Studies covered four major themes: records (n = 12), conservation (n = 7), ecology (n = 7), and evolution (n = 1), with studies increasing after 2000. Estimated argali density in Tsaba was 0.34 argali km-2 (0.32–0.40)  and in Chushul-Mirpal Tso was 0.15 argali km-2 (0.12–0.30). Both populations had comparable demography including age-sex ratios. We need to urgently consider argali as a priority species for conservation in India particularly as threats—including transboundary concerns, lack of coordinated conservation across the international border, anthropogenic disturbances, competition & disturbance from livestock grazing, and habitat loss—are a reality. Towards that, we delimited knowledge gaps and set robust population baselines for the two important argali populations in India. As the Tibetan Argali here co-occur with people, it will be crucial to ensure conservation is done in partnership with local communities.
