The entire study area (ca. 25 ha) was surveyed and ages of all junipers were determined by counting the annual rings and measuring the main stem diameter. The age-specific life table was then constructed from detailed observations on mortality and recruitment. In addition, different seed characteristics including length, diameter, weight, average number of seeds per cone and percentage of filled seeds were assessed. Based on the results obtained, production of relatively good quality seeds by individuals is the most important basis for maintenance of natural regeneration. Present study suggests that the juniper population in Mishu-dagh survives due to not only good seed features but also individual longevity, inertias which partially counteract losses to unfavorable environmental conditions delays the possible extinction course. These inertias would maintain populations through the critical regression period imposed by the present climate with continual drought period.]]>Aizen, M.A. and P.
