Abstract

The paper presents the results of the complex analysis of the flora structure of the state natural sanctuary "Bushkovskiy forest". The research had been made on the area of 9274.8 ha within the period of 2004–2023. Route recognition method was used together with geobotanical description of certain phytocoenoses on temporary sample plots made according to traditional methods. There vascular plant flora contains 270 taxon from 196 genera, 73 families, four classes and three divisio. On the territory of the sanctuary a rare species grows which is registered in the Red Data Book of the Russian Federation – Epipogium aphyllum Sw. The plants are distributed into 13 ecological-coenotic groups. As for the number of species, the floodplain meadow (21.9%), nemoral (17.0%), and boreal (12.6%) groups prevail. Among biological types hemicryptophythes prevail (49.6%); as for the biomorphological structure, dry ground grass polycarpics prevail (65.2%), and, among the latter, short rhizomatous (18.1%) and long rhizomatous (17.4%) grasses prevail. Plants of six hemerobia stages are represented in the flora, for a total, anthropophobic species (species of the a-o-m interval) account for 69.0%. Correlation of hemerobia stages, as well as a small share of adventitious species (3.0%), shows that the natural ecosystem of the sanctuary suffers from a certain anthropogenic load.
