Abstract

The basic trends of vegetation dynamics in meadow ecosystems of the Central Caucasus under the impact of current climatic changes were revealed on the example of sub-alpine meadows of the National Park <<Prielbrusye>> and Sukan plot of the Kabardino-Balkarian State High-Mountain Reserve. In the past 20 years, in the mountains of the Central Caucasus, during the period of active vegetation, the temperature increased by 0,46~С and precipitation by 16,24 mm, respectively. Humid subalpine meadows, which are indicators of climatic changes, are therewith more susceptible to climatic changes. Significant changes were registered in the following geobotanical and ecological parameters per 6--7 years. Mesophytous subalpine meadows are less susceptible. Steppe subalpine meadows are insignificantly responsive to current climatic changes.
