ANALYSIS OF THE SPECIES DIVERSITY OF BIRCH FORESTS ON THE RIVERBED TERRACE OF THE ESIL RIVER

The research work is devoted to the study of the diversity of vegetation of birch forests on the above-floodplain river terrace of the Esil River within the Kzylzhar region of the North Kazakhstan region. Based on the analysis of the author's surveys of the studied areas, a conclusion was made about the floristic composition of the vegetation on the right bank of the Esil River. A list of species was identified, the generic and species composition of the studied plants growing in the river floodplain was studied.
Based on our research work, 150 species from 117 genera and 46 families were identified. Among angiosperms (Magnoliophyta), numbering 147 species (98%) from 114 genera (97.4%) and 43 families (93.4%). Dicotyledoneae prevail - 125 species (83.3%), from 94 genera (80.3%) and 34 families (73.9%). The Monocotyledoneae class includes 22 species (14.67%) from 9 families (19.5%) and 18 genera (17.1%). The dominant families in terms of the number of species are: Asteraceae, Rosaceae, Poaceae, Fabaceae and Brassicaceae. Large genera contain 3-4 plant species: among them the genus Artemisia, Galatella, Trifolium, Rubus, Plantago.
