Abstract: Despite their ecological and cultural significance, the mountain grasslands of Kashmir Himalaya remain poorly studied. In this context, this study classifies the vegetation of high altitude grasslands of Gurez valley, Kashmir, with a focus on the influence of various environmental factors on the distribution of different vegetation groups. It also highlights the variation in the species distribution along an altitudinal gradient. Field data collected at 35 sites across three grasslands during 2008-2010 was analysed through TWINSPAN (Two way indicator of species analysis) and DCA (Detrended Correspondence Analysis). TWINSPAN classified the abundance data into nineteen plant associations that were confirmed by the application of DCA, albeit with some overlap. These associations could be clustered for three major vegetation groups that were closely linked to altitude and human disturbance. The highly disturbed plant associations were at lower altitudes and were less diverse as against the least disturbed higher elevated types that were largely stable but had a restricted distribution. In contrast, the mid-elevational plant associations showed a high internal variation and had many locally dominant species. The data generated will be helpful in providing an insight into the trends in vegetation dynamics, conservation status of various plant species besides being crucial to our understanding of biological diversity of this region as a whole.
