| Popis: | During past few decades, worldwide various ecological alterations have been experienced after treat and decreasing of glaciers. Notable changes have been traced in Khersan glacier, Central Alborz of Iran by monitoring since 2013 to 2015. According to our studies, Khersan glacier surface reduced since 1991 and this significant reduction led to many ecological alterations. Species elimination close to the glacier, displacement of various flora from sub-Alpine to Alpine and Nival area including changes in floral frequency are notable alterations taken during glacier retreat. A large number of studies in Khersan glacier area since last two centuries have evidenced complete elimination of 6 plant species. Displacement of 16 plant species during recent years revealed that such species after retreat either found a new location for the establishment or got eliminated. Besides natural changes, the glacier area was also affected by man-made developments. Perhaps new condition puts many plant species in conservation level which need proper care programs. In this study multidimensional scaling model (MDS) is used to show the Nival areas where species are under much stress. Proper evidence has been tried to put forward for describing such changes. |
