Based on the count data obtained by various methods and their statistical processing, the abundance of the autumn population of Tetrax tetrax in the Saratov Trans-Volga region was estimated from the late 1990s till now. From 2012 to 2016 it averaged about 30,000 individuals, and in the Right Volga Bank region it was one or two orders lower, the species’ distribution there was sporadic. When studying the T. tetrax abundance dynamics, an increase in its population on the studied territory in the first half of the 2000s was established.
