Abstract

This study is focused on ecology and dynamics of the vegetation and the forest mountain flora in the Aur\`es area. It’s articulated on 3 parts. In the first part, the presentation of the study area from environmental and bioclimatological was performed. The second part is devoted to the ecology of the vegetation and flora of the Aur\`es . It is structured into 6 chapters. Aspects relating to the patrimonial interest of the flora of the cedar plantation of Ouled Yagoub and with the ecology of the species relic in the area of Aures (Juniperus will thurifera L) were studied. The last three chapters are devoted to the vegetation of Ch\'elia from typology point, determinism ecopedologic and anthropic perturbation. The last part is reserved for dynamics of the vegetation, by using different approaches. The geomatic analysis shows a clear regression of the forest formations, whereas the diachronic study over ten years of the flora reveals also an evolutionary tendency towards the open and degraded formations. The pedoanthracologic study which enabled us to recall the phytohistoric area reveals forest mediums with oak zeen and yew formerly largely answe
