Таксономический анализ флоры сосудистых растений лесной опытной дачи Тимирязевской академии

Abstract

At the present stage, the most important environmental issues include the problem of preserving biological diversity, which is especially relevant for natural landscapes located in urbanized conditions. In the forest areas under the conditions of anthropogenic impacts, the transformation of the regional flora takes place, thereby it adapts to the action of environmental factors. The aim of the study was to analyze the taxonomic structure of the vascular plant flora of the Forest Experimental Station of the Timiryazev Agricultural Academy (Moscow). Materials on the formation of the floristic list of the Forest Experimental Station were obtained during inventories of permanent trial ones for the period from 2000 to 2022, as well as route surveys of the territory in 2019-2022. In addition, a vascular plant download from the GBIF since 2000 was used. The study showed that the current floristic list of vascular plants of the Forest Experimental Station of the Timiryazev Agricultural Academy includes 352 species belonging to 202 genera and 68 families included in five classes. The largest taxa are the families Rosaceae, Asteraceae, Poaceae, Lamiaceae, Cyperaceae, which account for 52.3% of the species. In the Forest Experimental Station, 11 species of vascular plants listed in the Red Book of Moscow were identifi ed. The fraction of adventitious vascular plants in the flora of the Forest Experimental Station includes 99 species (28.1% of the total number of identified species), belonging to 66 genera and 34 families. Among the families of the adventitious fraction, the most multispecies are Rosaceae (22 species), Aceraceae (10 species), Asteraceae (7 species), Pinaceae (7 species). The proportion of adventitious species does not exceed 30%, so the fl ora should be considered natural, slightly disturbed. Despite the high level of recreation, pollution from road transport, the plant communities of the Forest Experimental Station continue to retain signs of a natural object that correspond to the natural conditions of the Moscow region.
