Lire la suite >The study, conducted between 2013 and 2014 in the rural commune of Bouchebka, situated in west-central Tunisia, focused on the Bouchebka national forest within the expansive Aleppo pine massif, covering 92% of the regional area. The primary objective was to conduct a comprehensive ecological inventory and characterization of the natural vegetation, emphasizing the impact of environmental conditions and human activities. The methodology employed a phytoecological analysis to quantify the richness and floristic diversity of the forest ecosystem in the Bouchebka mountains. Transects and floristic surveys were conducted through stratified and systematic sampling across various pre-identified plant formations.Statistical analyses, employing Factorial Correspondence Analysis (FCA), yielded significant results. The study unveiled that the forest predominantly consisted of Aleppo pine, marked by an abundance of young plants. The ecosystem encompassed 12 families, 17 genera, and 26 species. Furthermore, the biological spectrum of the area was defined, highlighting the prevalence of shrubs (41%). Species distribution was influenced by the ecological characteristics of the region, with 82% of species exhibiting xerophilic traits, indicative of an arid environment. Additionally, the presence of 32% of species dispersing through anemochory reflected the windy nature of the region.The factorial analysis underscored a pastoral aspect in the area, with cultivated species present, underscoring anthropogenic influence on the forest. Lastly, the phytological spectrum emphasized the predominance of woody species, suggesting a territory characterized by open and grassy spaces, indicative of an arid climate.Lire moins >
