The main environmental parameters that determine the spatial distribution of chamois in the high mountains of Dagestan in summer and winter were studied. The following landscape characteristics were studied: slope gradient, altitude above sea level, slope exposure, and additional parameters related to the defense of chamois (distances from detection sites to the nearest rocks, meadows, rhododendron bushes, etc.). The data on the localization and number of animals were analyzed. No seasonal differences in the distribution of chamois in relation to the slope gradient were revealed. In winter and summer, chamois prefers the slopes of 25°–35°. There were significant differences in the use of slope exposure by chamois depending on the season (χ² = 71, p < 0.001). The distribution of chamois at different altitudes above sea level had no significant seasonal differences.
