Herbaceous species of the subalpine ecotone are mostly influenced by canopy cover and soil organic carbon. Species such as Gentiana argentea, Geranium donianum, Kobresia sp., Potentilla griffithii, Rubia wallichiana, Rubus nepalensis, Thalictrum chelidonii and Thalictrum cultratum are supposed to be critically sensitive to local environmental conditions due to having narrow amplitude to both the analyzed environmental variables. Although we have single-time data set from the sole existing horizontal ecotone in the National Park, these indicator species could be vital for long-term assessment of the critical ecotone vegetation, especially in the present context of climate and land use- changes. Broaderscale replicated studies regarding these species would have a greater prospect in understanding climate- and land use- change mediated community dynamics of all the subalpine ecotone.
