Abstract
Palynological studies were carried out on three core-holes :K 1 5, K19 and K103. Tree vegetation pollen phases were dominant (Pinus associated or not with Quercus, Olea, Pistacia and deciduous trees), alternating with steppe type vegetation (mainly Chenopodiaceae and Artemisia). The respective changes of the different vegetal landscapes (forests, matorrals, steppes) are linked to climatic variations and are shown by the alternation of drought and humidity in the Mediterranean environment. The humid episodes have, above all, caused the southward migration of Mediterranean type vegetation which is now restricted to northern Tunisia. The bioclimatic sequences are found in the upper Pleistocene and the Holocene, between 27 230 ± 1 000 years B.P. and the recent epoch.
