This article is devoted to the study of Russian nature reserves, which are now changing their form and status as all organizations have done since the collapse of the Soviet Union. The author is mostly concerned with the study of the professional ethos of the ranger. The similarity of the rangers' ethos is determined by their common experience of work in the forest. The variability is explained by the difference in the environments of nature reserves, such as the proximity of a city or state border. The attempt to integrate this study in the corpus of works about social effects of nature reserves is made in the conclusion.
