| Popis: | Juniperus thurifera was selected for this study due to its crucial ecological role in high mountain ecosystems and the increasing threats it faces, such as habitat degradation and regeneration challenges. The analysis of stand structure by altitude shows that the distribution of individuals and stem count vary with elevation, highlighting the species’ adaptability to mountainous conditions. Altitudinal degradation significantly impacts seed production, with a positive correlation (r = 0.65) between stem and fruit numbers in females. J. thurifera also plays a vital role in soil retention, as indicated by the positive correlation (r = 0.511) between ground projection and soil thickness, emphasizing its importance in slope stabilization and erosion prevention. Sexual dimorphism reveals dendrometric differences between males and females, affecting regeneration and reproduction. Age estimation based on circumference shows the predominance of aging, non-reproductive trees, threatening future regeneration. Principal component analysis (PCA) further refines recommendations by revealing complex relationships between dendrometric characteristics and environmental factors, providing precise guidelines for J. thurifera conservation. |
