The article is devoted to the seasonal characteristic of vegetation communities and productivity dynamics in № 1 semiportable ecological platform of thekey site located on pasturable lands of the Matybulak rural district of Almatyregion. The field was made during a reconnaissance detour of the key area. Theroute is laid in view of the intersection of the main types of terrain. Geobotanicalwork included mapping of soil and geobotanical circuits on the key area andsemi-permanent sites. They are the study of the dynamics of productivity, thedependence of plant matter on the meteorological conditions. The next stepresearch involves the study of the dynamics of the formation of above-groundbiomass of all the types of plant communities and modifications semiportableecological platform № 2 and 3. It is undoubtedly helps to create a completepicture of the seasonal changes in the floristic spectrum of key area. The maintypes of fodder-producing areas with productivity determination are described,the preliminary list of plants is added, the main consistent patterns of heterogeneity of a vegetation cover and reasons of their occurence are determined. Themechanical structure of soils and the main type of a relief are defined. Composition of spring grass is not different diversity, floristic list for different types ofSPEG №1 includes 11-12 species. In the summer of productivity fescuenarrowly-lobedwormwood-ephemeral, turf grass-ephemeral, fescue-ephemeral communities was almost twice as high as the spring. In the autumn all ephemeradestroyed, floristic composition of the vegetation is reduced to 6-7 types.Key words: pastures, key site, communities of plant, aspect, formation, soil
