In this graduation thesis we were analyzing body indicators of red deer in the area of LPN Jelen Sneţnik, depending to population density in the period from 1976 to 2005. Analyzed body indicators are: body mass separated by sex and age category for all individuals, for adult male we analyzed also antler mass and CIC points of antler. Population density was reconstructed using reverse calculation, from data obtained from year harvesting. The results showed that the population density varied from 2,6 up to 5,8 individuals per 100 hectares. Analysis show that population density do not statistically significant influence the body weight of deer calves and yearlings. On the other hand we found statistically significant influence of population density on body weight for both sex of older animals. In analyzing the effects on antler weight and number of antler CIC points, we found a positive influence on them by older age and higher body weight, but they were influenced negatively by population density.
