The age composition of the population of the rare tree species Juniperus polycarpos C. Koch in Foothill Dagestan was studied according to the calendar age of individuals and their age states. The calendar age is determined by an index obtained as the number of annual rings per unit of radial growth of the trunk. Age states were assessed by vitality, productivity, infestation and size of individuals. The area occupied by the population, the number of individuals and the phytocenotic confinement of the species have been established. Biomorphological and biometric indicators, absolute age of individuals of various age states and their quantitative ratio were determined. Revealed the coincidence of the age groups of the population in terms of age structure and age spectrum, with a characteristic right-sided trend. The population is assessed as young, full-bodied, with a high level of renewability.
