- Abstract
The size and structure of the chamois (Rupicapra rupicapra caucasica) population as well as the influence of anthropogenic factors on it were studied on the Caucasian Reserve (Western Caucasus). The negative effect of the snow cover, the thickness of which differed from the usual level, is shown. The effect of winters with thick snow cover is confirmed by the relation between these factors and the proportion of yearlings in the population one year after the winter. An increased death rate of animals in winters with a deep snow cover is observed in the case when their density exceeds the optimal one. Wolf predation does not affect the chamois population on the reserve. The number of wolves increases with an increase in the chamois population density to 15–20 ind./1000 ha. The adverse impact of humans on the chamois population is manifested in the regions with motor roads. The chamois, as compared to the deer, suffers from poachers to a lesser degree because it inhabits inaccessible areas and its trophy value is low.
