The article presents the research and study of the peculiarities of morphological structure of vegetative organs of Cossack juniper (Juniperus sabina) growing in Karaganda (Karkarala and Zhanaarka districts) and Ulytau (Ulytau district) regions). Bioecological features of cenopopulations were studied based on the density of in[1]dividuals in the population, the ratio of life states and age states. According to the age structure, all juniper populations were defined as middle-aged, stable and full-members. The majority of individuals in the cenopopulations are categorized as healthy. The state of Juniper sabina gene pool is relatively satisfactory, but the increased proportion of senile individuals, especially in Zhanaarka district, requires measures to pre[1]serve juniper populations.
