Historique à long terme des feux de forêt de la sapinière de l’île Bonaventure en Gaspésie

Abstract: Les chablis et les épidémies d’insectes sont les principales perturbations qui régissent la dynamique des sapinières des régions maritimes. Bien que peu fréquents, des feux peuvent aussi survenir à l’occasion, mais on ne connaît pas leur historique à long terme (sur plusieurs centaines et milliers d’années). Nous avons reconstitué l’histoire des feux naturels ayant eu lieu sur l’île Bonaventure à l’aide d’une analyse pédoanthracologique. Située à l’extrémité est de la péninsule gaspésienne, il s’agit d’une pet… Show more

“…The first forests that burned during the lower Holocene were probably composed of conifers, especially spruces, while those of the upper Holocene were dominated by sugar maple and conifers including balsam fir. The Forillon site's pattern of fire frequency resembles that of a nearby site located on Île Bonaventure, D r a f t near the small city of Percé, at least in regard to an ancient period of fire activity that lasted from 8400 to 7800 years ago (Tremblay et al 2014). This direct proof of fire incidence during the lower and the upper Holocene also confirms the abundance of microscopic charcoals from around 8500 years ago and from 2500 years ago until today, collected by Asnong and Richard (2003) from a small lake near the municipality of Gaspé.…”
