En Finlande, des chercheurs ont mesur\u00e9 l\u2019impact de cinq strat\u00e9gies de gestion sylvicole, men\u00e9es dans un objectif de rentabilit\u00e9 \u00e9conomique, sur les services \u00e9cosyst\u00e9miques rendus \u00e0 la soci\u00e9t\u00e9 (production de bois, stockage de carbone, bilan carbone et biodiversit\u00e9). Ces strat\u00e9gies ont \u00e9t\u00e9 compar\u00e9es au moyen de simulations d\u2019\u00e9volution du peuplement sur une dur\u00e9e de 100 ans dans une zone de 43 000 hectares de for\u00eat bor\u00e9ale. Les cinq strat\u00e9gies sylvicoles \u00e9taient : la futaie r\u00e9guli\u00e8re avec \u00e9claircie par le bas, la futaie r\u00e9guli\u00e8re avec \u00e9claircie par le haut, la sylviculture \u00e0 couvert continu, une combinaison entre la futaie r\u00e9guli\u00e8re et la sylviculture \u00e0 couvert continu et une sylviculture appel\u00e9e d\u2019\u00e2ges multiples.<\/p>\n

Du point de vue de la rentabilit\u00e9 \u00e9conomique, la m\u00e9thode r\u00e9guli\u00e8re avec \u00e9claircies par le bas \u00e9tait de loin la moins rentable alors que les quatre autres se sont montr\u00e9es assez \u00e9quivalentes. La m\u00e9thode r\u00e9guli\u00e8re avec \u00e9claircies par le bas \u00e9tait \u00e9galement la moins int\u00e9ressante du point de vue du stockage de carbone (\u00e9cosyst\u00e8me et produits bois), du bilan carbone et des indicateurs de biodiversit\u00e9. La sylviculture \u00e0 couvert continu et la sylviculture d\u2019\u00e2ges multiples \u00e9taient quant \u00e0 elles les plus efficaces en mati\u00e8re de stockage du carbone (+24 % pour la sylviculture \u00e0 couvert continu) et de biodiversit\u00e9. \u00c0 la fin de la p\u00e9riode de 100 ans, les deux strat\u00e9gies r\u00e9guli\u00e8res montraient des stocks de carbone plus bas qu\u2019ils ne l\u2019\u00e9taient initialement. L\u2019\u00e9tude montre que, m\u00eame quand l\u2019objectif principal est la maximisation du revenu, il est possible d\u2019am\u00e9liorer la valeur des services \u00e9cosyst\u00e9miques rendus en optant pour des modes de gestion r\u00e9duisant les surfaces de mises \u00e0 blanc. L\u2019\u00e9tude a \u00e9galement montr\u00e9 la n\u00e9cessit\u00e9 de travailler sur le long terme lorsque l\u2019on s\u2019int\u00e9resse au carbone.<\/p>","protected":false},"excerpt":{"rendered":"
