Floral Diversity of the Tlemcen Mountains (Western Algeria)

摘要

Mountains of Tlemcen offer a very interesting model for studying the evolution of the flora in the region, since their landscapes variety remains very remarkable and the vegetation distribution is conditioned by a significant number of ecological factors. Although there were registered manyfires in the area during the 1990s, the coexistence of some species, such as Quercus faginea subsp. tlemcenensis (DC.) M., Pinus halepensis Miller., Calicotome intermedia (Salzm.) C. Presl., Lonicera implexa L., Ruscus aculeatus L., indicates a dominant ecological atmosphere of the forest. In this study, a phytoecological and syntaxonomical analysis was made. More than 300 species were identified and indexed, belonging to more than 50 families, which shows the importance of the phyto-diversity of the studied area. Based on the analysis of the phytoecological parameters, we could note a decline of the ground vegetation in its diversity.
