The article presents the results of a reconnaissance assessment of the state of biota in the area of the highway of Specially Protected Natural Territory “Sosnovaya Rosha” under construction in the city of Yoshkar-Ola (Republic of Mari El, Russia). The studied plant communities, especially mixed forests, in the forest park are characterized by a rather considerable diversity. A decrease in vitality was recorded in coniferous trees caused by low-quality drainage works. Assessment of environmental quality by IFA of the lamina of B. pendula trees has shown reasonably favorable conditions. All reservoirs are characterized by a high abundance of invertebrates. Currently, no sharp decline in the abundance of pedobionts have been noted. The diversity of dendrobiont insects with low abundance and the optimal ratio of phytophagous to predatory insects may indicate stable relationships between consorts and the determinant, a tree species. The distribution of amphibians and reptiles in the SPNT has mosaic character. We have also noted trends toward a decrease in species diversity and populations density of ornithofauna. At the moment, the road is not open for transport yet, and no sharp decline in species diversity or abundance of individuals in populations is observed.

“…On the territory of the permanent test area in the summer of 2021, the IFA of birch leaves ranged from 0.036 to 0.039. Since 2000, on this test area, we have been continuously studying the stability of B. pendula ontogenesis by morphogenetic FA indicators [13]. During this period, including the latest research in 2021, the state of model trees is assessed on the ontogeny stability scale [8] as optimal.…”

In the manuscript we described the results of the primary study of the state of environmental health in the protected forest park “Pine Grove” (Yoshkar-Ola, Russia). We found out the vital status 233 organisms of 10 important tree species for coniferous-deciduous forest. Severe damage was recorded in the plantings of Picea X fennica, Larix sibirica. We found drying of branches mainly in coniferous trees due to stagnation of flood water as a result of poorly carried out drainage works. FA index of the leaf plate of Betula pendula trees from the forest reached a value of 0.39. With IFA scale, the vitality of B. pendula is assessed as optimal, which indicates optimal environmental conditions in the territory of «Pine Grove».

“…We studied the seasonal dynamics of C. livia abundance during 2018-2019 and 2021-2022. The birds were counted by the route method, on a transect with a fixed width [7,8]. We counted the birds in the recreation area, in the city center.…”

In the manuscript, the authors described the results of the evaluation of the Columba livia population in Yoshkar-Ola (Russia). In the period from 2018 to 2022, the population density of pigeons in the city center increased by 15% and amounted to about 1,000 individuals per km2. The increase in the number of C. livia is not safe for humans. C. livia are most active during the day at permanent locations where they are fed by people. Of the five color morphs, dark-gray prevails. Pigeons belonging to the dark-gray morph are the most adapted to life in urban conditions. As part of the first phase of the project "Watch out, ornithosis!" from the Presidential Grants Foundation of the Russian Federation we conducted a survey of the citizens. As a result of the survey, we identified risk groups of the people due to ignorance about the features of the disease ornithosis. Older people feed pigeons more often and do not know about the diseases that birds carry. Schoolchildren also do not know about ornithosis. The next stage of the project will be the dissemination of preventive information about ornithosis and other diseases carried by pigeons, preventive measures.
