In this article we present the results of monitoring of ornithocomplexes of floodplain ecosystems of the basins of small rivers of Tula and Ivanovo regions on the example of the rivers Ptan and Vyazma for the period 2019-2022. There is given a characteristic of the composition and structure of the floodplain ornithocomplexes of small rivers of the zone of mixed forests and forest-steppe zone. The analysis of seasonal and multi-annual dynamics of the floodplain ornithocomplex is according to the main transformation indicators (species diversity and abundance). The previously developed methodology for assessing the transformation of coastal ornithocomplexes of regulated sections of small rivers located in intrazonal conditions has been tested. The relationship between the species composition and abundance of coastal ornithocomplexes has been established.

In this article we present detailed results of our study of the vegetation cover of the “Biologicheckaya Balka” or “Biological” dry valley, where the largest derivative of a ravine forest of the desert-steppe Trans-Volga region is located. The data on tree-shrub vegetation, soils and groundwater, taken from the stationary drill wells, was collected in different seasons of 2008-2021. The floristic observations were carried out by routing, with trees and shrubs studied along the way during the growing seasons of 2014 and 2018-2021. “Biological” dry valley (length – 850 m, elevation difference – 17 m) differs distinctly from the surrounding saline plains that are formed by the zonal semi-dwarf shrub-bunch grasses desert steppes. Its extremely small territory has intrazonal and extrazonal mesophilic vegetation, an unusually high floristic abundance and phytocenotic diversity. At the valley mouth there are halophytic annual saltwort plants, thickets of reeds, followed by the grass-forb communities with Phragmites australis further above, with meadow and forb-grass communities, and with a specific tarragon and couch grass meadow at the very top. Most of the area is occupied by a tree-shrub massif, located in the middle part of the valley bottom, and by the shrubs-forb-grass steppes on its right slope. In the catchment areas and on the left slope various types of desert and dry steppes are common, close to the vegetation of the flat interfluves. Their vegetation is heterogeneous and mosaic.

We also explain what role the most important environmental factors, such as the level and salinity of groundwater, surface runoff, slope orientation, pyrogenic factor, livestock grazing and erosions, play in the spatial organization and vegetation dynamics. Over the past 50 years the upper border of the closed tree-shrub massif has moved along the bottom of the valley almost 50 m up. The local flora consists of 201 vascular plants species from 44 families, which is about 30% of species and 80% of families of the total number in the Elton Region; including 4 species from the “Red Data Book of the Russian Federation” (2008), and 5 from the “Red Data Book of the Volgograd Region” (2018). There are also 30 or 15% ruderal species.

The materials of this study contribute and help to achieve the main strategic goals of the UNESCO biosphere reserve “Lake Elton”, such as the protection and restoration of natural ecosystems, development of scientific researches, ecological monitoring, ecological education, enlightenment and education. They prove there is a need of a protection regime in the “Biologicheksya Balka”, as well as of fire-preventing and graze-prohibiting measures.
