Eléments d’histoire du cèdre dans les montagnes méditerranéennes

Abstract : The Cedar appeared in Europe during the Early Cretaceous period. During the Tertiary era it was present but not abundant. From a compilation of pollen data (2012), Magri described the stages in its final extinction in Europe 600,000 years ago. To better understand this decline, the history of Cedrus atlantica forests in North Africa is briefly outlined. In Morocco several studies have shown the correlation between the Holocene changes in Cedrus distribution with past climate changes and human disturbances. In Eastern Algeria and Kroumiria (Tunisia), Cedrus forests expanded in the lower part of the mountain belt at the end of the last glacial period but during the Holocene they disappeared or, when possible, moved to higher altitudes (Djurdjura). There, as in Morocco, the Cedrus forests are certainly endangered by the present-day climate warming. Plantations in selected Mediterranean mountains within Europe could contribute to the survival of this beautiful tree
