Depuis quelque temps, la fili\u00e8re \u00ab bois \u00e9nergie \u00bb se tourne vers les r\u00e9sidus de r\u00e9colte pour r\u00e9pondre \u00e0 une demande croissante. Les enjeux associ\u00e9s \u00e0 la r\u00e9colte des r\u00e9manents n\u00e9cessitaient la mise en place d\u2019\u00e9tudes sur les impacts environnementaux. Celles-ci ont \u00e9t\u00e9 financ\u00e9es par l\u2019ADEME (Fr).
\nCes \u00e9tudes se sont appliqu\u00e9es \u00e0 comparer les impacts entre une r\u00e9colte conventionnelle de bois fort et des r\u00e9coltes plus ou moins intensives (figure 1) allant jusqu\u2019\u00e0 l\u2019export de la totalit\u00e9 des r\u00e9manents : grumes, branches, feuillage et souches.
\nLes diff\u00e9rences sont notables en termes de perte de carbone et autres nutriments dans les diff\u00e9rents horizons du sol. L\u2019\u00e9tude estime en outre une perte de 3 \u00e0 7 % de productivit\u00e9 du peuplement apr\u00e8s une r\u00e9colte intensive mais gage que la perte soit plus importante en cas de r\u00e9coltes successives. Les impacts sont d\u2019autant plus significatifs lors des premi\u00e8res \u00e9claircies en jeune plantation ou en cas de r\u00e9colte d\u2019un taillis simple\u00a0ou d\u2019un taillis sous futaie.
