VEGETATION STATUS OF THE UST-BUOTAMA RESOURCE RESERVE (BISONARIA) // Научно-методический электронный журнал «Концепт». – 2026. – . – URL: http://e-koncept.ru/2026/0.htm
The article presents the results of geo-botanical studies on the territory of the Ust-Buotama resource reserve. 45 descriptions were performed (36 meadow, 9 forest). 94 plant species from 26 families were identified. The pasture digression was assessed according to L.G. Ramensky, the productivity was analyzed by the cut method, and the Jaccard coefficients and the synanthropization index were calculated. It was found that 58.3% of the meadow communities are at 3-4 stages of digression, 30.6% are at 5 stages, and 11.1% are at 1-2 stages. In forest phytocenoses, the transformation of native spruce forests into birch forests was observed. The dominant family is Rosaceae (19.15%). The productivity ranges from 75 to 674 g/m², with the lowest values observed in the enclosure with the highest load. The results obtained indicate a high degree of anthropogenic transformation of the vegetation in the Ust-Buotama reserve, and the need to develop measures for regulating grazing in order to preserve biodiversity and restore disturbed communities.
