In order to investigate the ecological preferences and dendrochronological potentiality of Stone pine (Pinus pinea L.), simple visual analyses were carried out on 30 increment cores, 15 of which extracted from trees grown on a high dune and 15 from plants grown on a low dune. Precipitations play the most important role on tree-ring growth. Dry seasons were seen to play a negative influence on the growth of trees growing on the high dune but did not reduce the growth on the low dune. Ground water probably assures a better water availability to the trees growing on the low dune, which reach the water table with the whole root system. The Stone pine seems to be a dendroclimatolcgical sensible species.
