Our study focuses on the radial growth of juniper (Juniperus thurifera) in the Aurès massif at three stations: T'kout, Zana and Guerza. The results obtained showed that the average thickness of the rings (ECM) at the level of the three stations varies between 0.918 and 1.220 mm and seems much more heterogeneous at the level of the station of T'kout with a coefficient of variation 26% against 16 to 17% for the stations of Zana and Guerza. The highest average ring thickness is located in the station of Guerza (1.41 mm). This study shows that climate and altitude can affect radial growth at all three stations.
