De 2005 à 2010, près de 1,7 million d’hectares de forêts ont été brûlés au Québec. Une vaste proportion de ces peuplements ont nécessité des travaux de remise en production. Présentement, d’après des études fragmentaires qui indiquent que les jeunes forêts dominées par l’épinette noire ont un faible potentiel de régénération, les pessières âgées de...
Clearcutting practices combined with the predicted increase in fire activity may induce post-fire regeneration failure in boreal forest landscapes. This study aims (1) to evaluate if recently managed landscape by clear cut logging is susceptible to be affected by post-fire regeneration failure; and (2) to explore the ecological drivers of black spr...
Bien que les feux et les coupes soient les perturbations majeures au sein de la forêt boréale, peu d’études ont jusqu’à maintenant quantifié leur importance de même que leur impact sur la structure des paysages. Afin d’y parvenir, nous avons dressé le bilan des superficies touchées par les feux et les coupes depuis le début du 20e siècle, sur une v...
Context
Although logging has affected circumboreal forest dynamics for nearly a century, very few studies have reconstructed its influence on landscape structure at the subcontinental scale.
Objectives
This study aims to document spatiotemporal patterns of logging and fire since the introduction of logging in the early twentieth-century, and to ev...
Face à l’augmentation observée des accidents de régénération en forêt boréale et leur impact sur la productivité et la résilience des peuplements denses d’épinette noire, une meilleure compréhension des mécanismes de résilience et une surveillance des risques d’accident de régénération sont nécessaires. L’objectif principal de cette étude visait do...

We used historical (1940–2009) logging and fire maps to document disturbance patterns across a 195,000-km2 boreal forest landscape of eastern Canada. We produced a multitemporal mosaic providing land cover status using Landsat imagery from the 1970s to the 2010s to analyse the evolution of landscape structure.
This study aims to develop a predictive tool for black spruce post-fire regeneration using stand disturbance history, and climate/site conditions. First, we want to developed a theoretical model that combined spatial variables (stand/site/climate conditions) commonly used by forest managers in eastern Canada, a fire severity index (“differenced normalized burn ratio”, or dNBR) and variables collected by in situ sampling (residual organic matter, tree age, twig severity index). Second, we will developed a spatially explicit model to predict post-fire regeneration using only spatial variables readily available in existing datasets. Our model will allow to incorporate climatic scenarios and will permit to evaluate post-fire resilience and productivity of boreal forest in a context of global change.
