Reproductive characteristics (e.g., pollen, strobili, cones, seeds, and fruit) are one of the main tools in sustainable forestry. However, many biotic (e.g., growth characteristics, species, population, and individual) and abiotic (e.g., edaphic, climatic, geographic, and year) factors can affect these characteristics. In this study, the impact of climatic characteristics, including minimum, maximum, and average temperatures, annual total precipitation, and relative humidity, on female and male strobilus production was examined in three natural populations of Taurus cedar (Cedrus libani A. Rich.) during three consecutive years (2020–2022). For this purpose, fifty trees were sampled randomly and marked in each population to observe strobilus production. Analysis of variance showed that climatic characteristics were similar (p > 0.05) among years and among populations, while female and male strobilus production showed significant (p < 0.01) differences among years, among populations, and among years within populations. In contrast, interactions of population × year were not significant (p > 0.05) for climatic characteristics. Two populations had the highest strobilus production (155.4 and 82.3 for females and 889.4 and 186.1 for males) in 2022. The studied climatic characteristics had no significant (p > 0.05) effects on strobilus production. The results of the study emphasized similar forestry practices in local areas based on climatic conditions.
