Ecosystem-based management (EBM) presumes that sustainability is a function of how well we understand ecosystem function and ecological dynamics. This includes understanding relationships among climate, disturbance, vegetation patterns, and ecological services. Recent research on the historical ecology of montane forests in western Canada has challenged the long-standing notion that stand-replacing fires characterized the landscape. Instead, […]

Ces dernières années, le biobutanol a attiré l’attention dans le domaine de la recherche car ses propriétés sont supérieures à celles l’éthanol telles que sa valeur énergétique et son indice d’octane, il peut donc être un substitut de l’éthanol dans l’essence sans toutefois impliquer les problématiques généralement associées à l’éthanol (tel que l’hygroscopicité). De plus, […]

Les chemins forestiers sont indispensables tant pour l’industrie forestière pour accéder à la ressource ligneuse qu’aux collectivités pour profiter des services écologiques rendus par les écosystèmes, par exemple la villégiature, la chasse ou la cueillette de petits fruits. Mais les chemins sont aussi reconnus pour leurs nombreux effets négatifs sur les écosystèmes aquatiques et les […]

To responsibly manage forest resources in southwestern Alberta, it is important to understand the disturbance regimes they have experienced in the past, are experiencing now, and are likely to experience in the future. The Mountain Legacy Project has several thousand repeat photographs which show areas of the mountains and foothills of the Rockies a century […]

Les peuplements de pins gris sur sables sont des stations forestières peu résilientes en cas de perturbation ou de changement dans la dynamique de végétation. Dans certaines conditions, l’aménagement forestier peut favoriser le basculement d’une forêt productive vers un état de clairière ouverte. En identifiant les facteurs en cause dans le déficit de croissance du […]

An emerging strategy for managing natural resources such as Canada’s forests more sustainably and responsibly is to use knowledge of how Mother Nature has done it to help guide our hand. This so-called ‘ecosystem-based” approach has gained favour with provincial and federal governments, as well as national and international certification agencies. One of the foundations […]

The Bicknell’s thrush (Cathurs bicknelli) is a rare songbird with the most restrictive breeding range in North America. The Bicknell’s thrush spends its summer months breeding in high elevation, stunted growth forests – a habitat that the species specializes in. In New Brunswick, there has been a documented population decline of 11.5% per year since […]

City trees and forests provide numerous ecosystem services (e.g. cleaner air, cooler environment, recreation) to human society but they are increasingly threatened by the changing climate, urban sprawl, invasive pests and diseases. This is particularly the case for Eastern Canadian cities that see the need to replace a large proportion of their trees killed by […]
