Abstract— Pinus halepensis Mill., is a most common tree in the Mediterranean basin. In Tunisia, specifically Kroumirie, it is an excellence species. However, for several years, we assist a continual deterioration of this ecosystem type. Several factors are the origin for this degradation: insects and fungi attack, fire, aging populations, low regeneration and hardening climate. This degradation is further accentuated by installing careers around the pine forest. Our objective in this study was to identify the career dust influence on growth and productivity of Aleppo pine; through dendrochronological approach (tree rings study) and dendrometric approach (measurement of diameter, height and survival rate). Study is accomplished on two populations: a reference site ‘Charchara’ located away from mining and Oued el maaden site near a gravel extraction career. In addition, physical and chemical parameters are analysed on soil and water samples collected in the two sites. Results showed significant differences of parameters studied between stations both in dendrometric and dendrochronological parameters over time. Second, in physical and chemical parameters, a very high content on metals traces was found on soil and water in Oued el maaden site.
Keywords— career, growth, Pinus halepensis, productivity.
