This article is dedicated to the study the causes of population dynamics of the demoiselle crane, starting from the beginning of the twentieth century and ending with the current state of the population of this species. The paper discusses the biological characteristics of the species, the number and change in the locations of the demoiselle crane in different periods of time are considered. A detailed analysis of the range change was carried out (based on the icon method: applying the found demoiselle nesting places to an electronic interactive map and highlighting the approximate boundary of the habitat of the crane belladonna in the three depressions of Ubsunursk, Uregnursk and Minusinsk located within Krasnoyarsk Krai, Tuva and Khakassia). The possible reasons for the disappearance of the demoiselle in the territory of Central Siberia in the middle of the twentieth century are highlighted. Vulnerability magnitude was analyzed and determined based on the biological properties of the species, as well as the analysis of anthropogenic influence. On the basis of the materials studied, in this work a widened increase in the number of demoiselle cranes at the beginning of the 21st century was marked, as well as highlighting the main reasons for the increase in the number of individuals at the current time. Besides, this article addresses the problem of the state of knowledge of the demoiselle crane and the systematization of the information received about this species. It also raises the question about the change of the status of demoiselle crane in the Red List of the Krasnoyarsk krai.
