Far from being Mediterranean, the predominant micro-climatic conditions in the gorges resemble more those of mountainous regions; less light, higher moisture, trapped cold air. It is therefore not a coincidence if we can see unusual species here in Provence, such as the European beech (Fagus sylvatica), the Alpine Buckthorn (Rhamnus alpina), the Mountain Currant (Ribes alpinum), or the magnificent Turk's cap lily (Lilium martagon).
