The author describe -with the examination of biological sciences -the problem of forest production in the north of France and Picardie. The pro tection must be function of the hierarchy of bio-ecological and environmental values of each forest clump. The author propose a method of valuation. The three elements of the forest function are entered upon conservative and biological aspects -regarding the forest exploitation : the potential associations of the region, the genecology of trees, the botanical sites -regarding the chase : the big fauna , the traditions -regarding the forest touring : a strategy for a not-motoring penetration.L'auteur fait le bilan -du point de vue des sciences biologiques - du problème de la protection des forêts du ...
