摘      要：In an era of climate change,the availability of empirical data on alpine summit vegetation in the Himalaya is still *** we report the assessment of alpine summit flora in Gulmarg Wildlife Sanctuary,Kashmir *** employed a globally standardized Multi-Summit Approach and four spatially isolated summits spanning an elevation gradient of 210 m(between 3530-3740 m a.s.l.)from natural treeline to nival zone were *** of the summits was carried out in the year 2018 to collect floristic data together with records of soil temperature.A total of 142 vascular plant species were recorded in the sampled *** of the species were of herbaceous growth form and with perennial life *** on Raunkiaer’s life form,hemicryptophytes were the most dominant followed by therophytes and *** summit flora showed the predominance of narrow-endemic species,with broad-and non-endemics declining with elevation.A significant relationship between growth form,Raunkiaer’s life form,and the degree of endemism with elevation was *** species diversity and soil temperature showed a monotonic decrease with increasing ***,soil temperature clearly determined the magnitude of species diversity on the ***,based on floristic composition,the lowest summit had the highest dissimilarity with the rest of the *** present study employed globally standardized protocol to scientifically assess the patterns of plant diversity on the alpine mountain summits of Kashmir Himalaya,which in turn has wide implications towards long-term monitoring of climate change impact on alpine biodiversity in the rapidly warming Himalaya.
