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.

The influence of spring hunting on geese has long been recognized throughout the world as the main component of the decline in their total number. Unfortunately, the spring hunt for migratory birds, which has long been abandoned by all European, part of Asian and North American countries, is still underway in Russia. This negates the efforts of specially protected natural areas to preserve rare species of Anseriformes. Restrictions on spring hunting at the regional level can be introduced with great difficulty, mainly due to the powerful hunting lobby. Measures to restrict spring hunting in the Republic of Kalmykia were carried out from 2008 to 2012, and during this period, an increase in the number of this species was noted. In 2019, after no measures were taken to restrict hunting in the Republic of Kalmykia, a smaller number of red-breasted goose at the stop can be noted compared to the one when restrictive measures were in force. In our opinion, the results of the study are a good illustration of the strong influence spring hunting has on the populations of Anseriformes, which are forced to use only a part of the territory suitable for migratory stops. The most effective measures will be the complete closure of the spring hunting for waterfowl in the Kumo-Manych depression and the creation of temporary mobile resting zones on key water bodies of the depression during the autumn-winter hunting season. In 2020, thanks to this study, the regional hunting parameters prohibited spring hunting for waterfowl on the territory of the Kumo-Manych depression in the Republic of Kalmykia and Stavropol district.

This article presents scientific evidence of the negative influence of the disturbance factor during the spring hunting period on both rare and hunting species of geese. This study can serve as an example for other regions of Russia, where it is required to introduce restrictive measures during the spring hunting for waterfowl.
