Taxonomical analysis of the flora of vascular plants in the Forest experimental station of the Timiryazev academy

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 identified. 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 flora 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.
