This paper presents the results of monitoring the current state of natural complexes and rarespecies of plants and animals in the special protection natural areas (SPNA) to conserve fauna and flora, listed in the Red Book of Volgograd Oblast. Bykovo municipal district of Volgograd region – “Tazhinsky estuary” and “Prishibo-Mogutinskaya system of estuaries” were selected as the object of the study. The initial materials of the study were the data obtained during field studies carried out from May to September 2021. The main purpose of the study has two components: an analysis of the current situation (the current status and number of rare species and natural complexes in general and in the area near the protected area (not more than 1 km) according to the study results) and identification of limiting factors and threats to each species and the natural complexes as a whole. The main methods used during the expeditions were continuous records of all vertebrates on long, multi-day automobile and hiking trails. At the same time, we searched for nests and breeding territories of birds in specific habitats and interviewed local people to identify habitats of large birds of prey and other rare species of birds. All rare species encounters were positioned with a Garmin Etrex 30x GPS receiver. Traditional geobotanical methods (ecologicalphytocenotic and ecological-floristic analysis of phytocenoses) and quantitative methods (analysis of the species composition of phytocenoses by pairwise conjugation and analysis of floristic and phytocenotic similarity of phytocenoses), and the main sample-area method were applied during the study to study the species diversity of plant communities. The results and digital mapping of the results of field studies have shown that the areas of special value for the conservation of fauna and flora listed in the Red Book of Volgograd region – “Tazhinskyestuary” and “Prishibo-Mogutinskaya estuary system” irreversibly degrade due to changes in the hydrological regime. These reclaimed estuaries have been very poorly filled with water in recent years, and in some years, have remained fully dry (this has been the case for the past two years). This leads to the progressive salinization of soils and the extinction of rare species for which these SPNAs were organized. Recommendations on possible changes in the regime of special protection, boundaries, and SPNA category were developed based on the analysis of the studies’ results. The additional survey of estuaries in late April-early May in a year with good moisture is required to decide on the future of SPNA.

The article discusses the results of monitoring the current state of the specially protected natural area (PA) “Tingutinskaya Lesnaya Dacha”, which is of particular value (OPV) for the conservation of flora and fauna listed in the Red List of the Volgograd Region. The causes and limiting factors of the majority of rare species are noted, leading to the need to maintain the regime of special border protection and the OPV category. The initial materials of the study were data obtained during field studies, which were carried out from May to July 2022. The main purpose of the study is to obtain data on the state of the natural complex and rare species of plants and animals. The main methods, used in the study, were the accounting and assessment of the state of populations of rare plant and animal species in the field, digital mapping of the results of field studies. During the study, the dynamics of landscape fires on the territory of the studied OPV for the period 2002–2022 was specially analyzed. The burnt areas in the natural zonal landscapes of the Tingutinskaya Lesnaya Dacha PA were determined on the basis of visual interpretation of the Landsat-5, -7, -8 color RGB composites for 1998–2018, data from active combustion centers FIRMS and the product MCD45A1 version 6 for 2001–2018. The mapping of the modern landscape structure of the OPV was carried out on the basis of visual interpretation of images for the period of summer 2022 of the Sentinel 2 service.
