Voici ce que je propose mais attends la vérification d'un anglais de langue maternelle
à moins que tu veuilles garder une touche frenchy...
"On the 80 000 hectares occupied by the state owned forest of Ariège, ONF can do forestry on about 20 000 hectares. On this area the current aim is to remove 3m3/ha/year to reach the routine production of 60 000 m3/an. Since 2001 this aim has never been reached. The purpose of this study is to understand why and come out with solutions to the problem. According to us 3 reasons explain this failure: the objective definition methods currently used are far from satisfactory; the wood cut exploitation is not optimized; the market on which ONF is selling is not well disposed because it is not competitive enough.
To solve the problem, we come with 5 solutions: study of resources, exploitation diagnosis generalization, whole state database development, a more pragmatic forestry in the "hêtraie(???)" and a commercial procedure improvement."
Voilà pour le moment, bon je n'ai aucune idée de comment traduire hêtraie
Et je ne sais pas à qui c'est destiné mais peut être que tu voudras convertir les hectares en acres.
