Le Pin maritime dans le Sud-Ouest de la France : tables de production provisoires

Abstract

These yield tables concern a very important species in the Southwest ol France where it covers about 1 000 000 ha. They were calculated almost completely with data obtained from temporary plots which were mesured once sometimes twlce. The methods used basically a certain number of fundamental equations which describe the state and the growth of the stand ; they were obtained by multiples regressions. For these equations, and after having chosen a treatment (intensity, nature and period of the thinnings) we could built a model simulating the evolution of stands which have been treated in that way. The tables are thus for variable thinnings regimes.
