The Holocene began with the Preboreal, characterized here by open pine-birch forest with some mlaed oak thickets. Large to medium-size mammals included not only boar, red and roe deer and beaver, but also aurochs, horse and rare moose. In the climatic optimum of the Boreal phase, there was massive development of hazel, but the fauna remained the same. As in the Preboreal, boar, favored by the existence of clearings, was more abondant than red deer (Rozoy, 1978 (pp. vi, 328, 1057)). Aurochs is still present, as at Roche-aux-Faucons (Cordy, 1976). During the Atlantic period, which was more humid, a darker, more closed, dense mlaed oak forest spread throughout these regions, and was composed of as wide a variety of taxa as is presently the case (oak, linden, elm, various species of maple, asti, chestnut, hornbeam, birch, hazel, aider, poplar, mountain asti, wild cherry, service tree, two eiders, black aider, hawthorn, holly, juniper, and fate in this period, beech). But the main animais are still the same (red and roe deer, boar, beaver) and neither aurochs nor horse had completely disappeared (Dewez and Cordy, 1983), although red deer, an animal preferring copses, is now more abondant than boar.
