In the prestigious journal Acta Societatis Botanicorum Poloniae" appeared an article by the Garden's staff on the vegetation of the highest peaks of Central Asia. The purpose of the paper was to learn about the diversity of syntaxonomic The high mountain and subnival vegetation of the Pamiro-Alaya mountains and the western part of the range Tienshan. Based on the analysis of 303 phytosociological images, after applying multidimensional scaling (NMDS) and the dividing algorithm, fifteen plant communities were defined, including 13 new ones. In addition, three plant communities without rank were distinguished. Three new vegetation associations were established: Oxytropido savellanicae-Nepetion pamiricae For high-altitude subnival vegetation, Stipo regelianae-Ptilagrostion malyschevii For pinnate grassland and dwarf mountain tundra and Poo alpinae-Bistortion ellipticae For mesophilic alpine pastures. The main factors differentiating the species composition of the studied vegetation are the average daily temperature range, the sum of annual precipitation, the seasonality of precipitation, the temperature of the driest quarter and the precipitation of the coldest quarter. Further studies in neighboring regions such as the Hindu Kush, Kopet-dagh and Altai, will be implemented to build a coherent hierarchical system of high-mountain grasslands and vegetation Khazmophytic. Next year, members of Prof. Nowak's team will embark on an inventory of the Altai halls of Kazakhstan.
