Monitoring was carried out to search for all 107 species recorded in the Red Book (2015) in the mentioned area and species left in that area by 2021. 79 species of animals were found.

The status of protection of the savka and bustard should be changed to the first category, the little bittern, white-eyed pochard and the Eurasian hoopoe -to the second category, the red-necked grebe, Siberian salamander and the gray-cheeked grebe, Siberian salamander and the greater spotted eagle - to the fifth category of rarity status.
