At present, much attention is paid to the study of the adventive component of the flora of urban forests, the appearance of which is due to anthropogenic impact. The aim of the work is to evaluate the contribution of alien species to the diversity of the flora of the Forest Experimental Station of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. Adventive species from the current floristic list of the Forest Experimental Station were identified. It was established that 99 vascular plant species belonging to 66 genera and 34 families are adventive. The largest number of these species belong to Magnoliophyta (91 species). Among the families of the adventive fraction, Rosaceae (22 species) and Aceraceae (10 species) are the most multispecies. The dominant position is occupied by the genus Acer, which includes 10 adventive species. The analysis of the florogenetic structure revealed that most of the representatives of the adventive flora are representatives of the North American, European and European-West Asian florogenetic groups. This is associated with the introduction experiments in the Forest Experimental Station. An analysis of the distribution of species of adventive flora of the Forest Experimental Station by life forms indicated the predominance of trees (38%) and shrubs (34%) over herbaceous plants (28%). It was established that the proportion of adventive species in the flora is 28.1%, which allows it to be considered natural and slightly disturbed and indicates the resistance of plant communities to an aggressive urban environment despite the high level of recreational load and pollution from road transport. The biogeocenoses of the Forest Experimental Station continue to retain signs of a natural object that correspond to the natural conditions of the Moscow region.

The authors of the article announce a new Russian scientific electronic journal “Timiryazev Biological Journal” founded in 2023, but having more than 150-year history. The most important mission of the journal, according to the authors, is to provide highly qualified information support to topical biological research, for which a solid team of editors and reviewers, who are experts in different branches of biological sciences, is created. The authors invite scientists as well as their young colleagues, post-graduates and PhD students to publish in the journal “Timiryazev Biological Journal”, and express the hope that in the near future the journal will become an important platform for biologists to exchange relevant scientific information, and continue to develop the traditions of academic and applied science, established in the walls of the oldest agrarian university In Rusia Russian State Agrarian University – Moscow Timiryazev Agricultural Academy.
