In this article we present the analysis results of the materials that were obtained during the autumn and spring-summer field studies in 2020-2021. The studies took place in the upper reaches of the Vyazma River (left inflow of the Uvodi River), and in the forest-marshlands of the northern part of the zone of mixed and deciduous forests in the southwest of the Teikovsky District, one of the central in the Ivanovo Region. The aim of the studies was to investigate the state of floodplain ecosystems under the increasing anthropogenic impact and climate change. We studied the physical and geographical features of the area, and carried out the geobotanical and soil researches of the Vyazma River valley and wetlands. This helped us to determine the composition and structure of individual ecosystem components, such as soil and vegetation, in the river floodplain in the north of the mixed and deciduous forests. In this article we analyzed the literary sources and studied the data of the autumn and spring-summer ornithological censuses that took place in 2020-2021. We provide an ecological characteristic and an actual assessment of the coastal ornithocomplexes (species diversity, birds’ number and abundance in the bog-semi-aquatic complex) and the forest-bog ones under anthropogenic impact. We determined the main features of this transforming environment, because they are the leading factors influencing the changes in the aviafauna of the Vyazma River valley.
