Climate change is altering insect disturbance regimes via temperature‐mediated phenological changes and trophic interactions among host trees, herbivorous insects, their natural enemies in boreal forests. Range expansion increase outbreak severity of forest insects are occurring Europe North America. The degree to which northern ecosystems resilient novel will have direct consequences for the provisioning goods services from these forests long‐term management planning. Among major ecological...
Forest plantations are recognized as a silvicultural tool for ensuring timber supply that meets public expectations regarding sustainable forest management. However, they also part of the scenario shows greatest potential artificialization natural forests. From firsthand perspective, intensive plantation silviculture objectives may appear antagonistic to those ecosystem Here we describe process through which defined and documented issues, then propose solutions allow integration into We...
Abstract Aims Selective browsing can be a chronic disturbance that reduces the survival, growth and reproduction of individual species shapes composition structure plant communities. Along with other disturbances perturb forest ecosystem, may thus affect regeneration successional trajectories after an acute perturbation such as clear‐cutting. However, effects different pressures on species, communities ultimately succession remain hard to predict. Methods We implemented exclusion experiment...
We evaluated the effectiveness of commercial thinning mainly from below (CT; 0, 26%, 32% and 40% merchantable basal area removals) in meeting wood production demands developing structural heterogeneity a balsam fir (Abies balsamea (L.) Mill) spruce (Picea spp.) stand. After 10 years, 32%–40% removals showed 12%–18% increase mean diameter 27%–38% gross volume (GMV) per tree compared to unthinned control. At stand level, all treatments generated as much cumulative GMV (harvested + after years)...
One-quarter of forest areas worldwide are managed for forestry purposes. Depending upon the type practice and intensity management, may alter forests to various degrees raise sustainability issues. To mitigate alteration natural by promote sustainability, ecosystem management has been implemented widely over past quarter century. A need remains development comprehensive operational assessment approaches validate its effectiveness. Naturalness could be used effectiveness since this concept...
L’aménagement écosystémique nécessite une bonne connaissance de base des écosystèmes vierges et leur fonctionnement. Toutefois, dans la plupart régions du Québec, le paysage forestier d’origine a été altéré par les activités humaines. Afin valider gestion effectuée en Basse-Mauricie, préindustriel hautes collines Bas-Saint-Maurice caractérisé l’analyse 18 inventaires forestiers l’industrie pâtes papiers datant début 20 e siècle.

The knowledge of natural disturbance dynamics and preindustrial landscapes is essential to implement sustainable forest management. Recent findings identify the lack a model, different from standard cyclic model Baskerville (1975. For. Chron. 51: 138–140), for balsam fir ( Abies balsamea (L.) Mill.) ecosystems maritime eastern Canada. With use historical maps dendrochronology, we reconstructed range variability landscape (6798 km 2 ) inferred on Anticosti Island. was characterized by matrix...
Forest vegetation management can improve planted seedling survival and growth is thus widely used in plantation silviculture. In some jurisdictions, mechanical release using brushsaws has replaced the traditional use of chemical herbicides for forest purposes. However, its associated costs increasing difficulty finding qualified labor represent a challenge. The browsing competition by large herbivores may an alternative to when seedlings are resistant browsing. Here, we compare efficacy...
In the boreal forest, ground-layer composition may modulate effects of precommercial thinning (PCT) on stand productivity by affecting tree growth conditions. Based data from 15 years PCT monitoring in black spruce (Picea mariana) and jack pine (Pinus banksiana) stands, objectives this study were to investigate way is related growth, productivity, impact productivity. favored lichen expansion xeric sites. The positive after was lower sites with high year-one cover, suggesting that...
Plantations offer a high potential to respond the increasing pressure on forests deliver social, economic, and environmental services. Exotic tree species have long history of use in plantation forestry, mostly because their improved productivity compared with that native species. Because impacts land management environment, questions arise regarding compatibility exotic plantations sustainable forest (SFM), overarching paradigm driving legislations Canada. Our objectives were thus i)...
L'autoéclaircie joue un rôle important dans le développement des peuplements forestiers. Ce processus écologique ne s'opère pas efficacement à l'intérieur de certaines sapinières boréales très denses. Dans ces sapinières, la croissance arbres a ralenti, ce qui diminué les services écosystémiques rendus par peuplement, tels que production matière ligneuse. Les principes sylvicoles l'éclaircie bas se basent sur d'autoéclaircie. Ainsi, l'objectif cette étude était vérifier si l'application...
RésuméLes plantations forestières représentent un outil sylvicole reconnu pour assurer approvisionnement en matière ligneuse qui répond aux attentes de la société envers l'aménagement durable des forêts. Toutefois, elles font aussi partie du scénario a le plus grand potentiel d'artificialisation forêt naturelle. Les objectifs sylviculture intensive peuvent alors paraître, prime abord, contradiction avec ceux écosystémique. Nous décrivons processus par lequel nous avons défini et documenté...
Commercial thinning enables forest managers to meet timber production objectives. Thinning reduces tree density alleviate competition for resources and favour growth of selected species. However, in doing so, can homogenize the composition mixed-species forests raise biodiversity issues. There is increasing evidence that species richness lead higher productivity through a complementarity effect. Hence, would maintain diversity could enhance stand help reconcile objectives The objective this...
Forest plantations play an increasingly important role in meeting global demand for wood. They usually have higher yield than naturally regenerated forests. Thus, can support economically viable wood production, enable forest conservation elsewere, help mitigate climate change by contributing to carbon sequestration and increase resilience resistance biotic abiotic stressors. If of is not as high anticipated, then their use could generate sustainability issues. There are still major gaps our...
