Un cadre conceptuel pour l’intervention précoce contre la tordeuse des bourgeons de l’épinette : Peut-on arrêter les épidémies?
Resource
The spruce budworm is a native forest insect that inhabits the spruce-fir forests of northeastern North America. Outbreaks of this insect occur every 30 to 40 years. During this cycle, populations...
Un cadre écologique pour soutenir l’utilisation de solutions de rechange aux herbicides dans les forêts boréales et tempérées septentrionales de l’Ontario et du Québec : Première approximation
Resource
We present an ecological framework for classifying sites to support vegetation management decisions in the boreal and northern temperate forests of northeastern Ontario and northwestern Quebec. This...
Un compendium de sites expérimentaux et d’études scientifiques dans le bassin des lacs Turkey
Resource
L’Étude du bassin des lacs Turkey (BLT) est une étude fédérale et interministérielle lancée en 1979 pour analyser les effets des pluies acides sur les écosystèmes terrestres et aquatiques. Le bassin...
Un vent de changement souffle sur les essences forestières canadiennes
Resource
With climate change, Canada’s forests will be exposed to rapid changes in their environment, including variations in temperature and precipitation. Tree species will have to migrate to find the...
Uncovering Traits in Recovering Grasslands: A Functional Assessment of Oil and Gas Well Pad Reclamation
Resource
Results suggest that even as practices and policies evolve, reclamation does not fully alleviate the legacy effects of industrial disturbance. Trait-based approaches can inform recovery assessment.
Undermining Subsistence: Barren-Ground Caribou in a “Tragedy of Open Access”
Resource
The paper describes a “tragedy of open access” occurring in Canada’s north as governments open up new areas of sensitive barren-ground caribou habitat to mineral resource development. A growing body of science and traditional knowledge research points to the adverse impacts of resource development; however, management efforts have been almost exclusively focused on controlling the subsistence harvest of northern Indigenous peoples.
Understanding and Responding to the Effects of Climate Change on Alberta’s Biodiversity
Resource
The Biodiversity Management and Climate Change Adaptation project has produced a comprehensive, evidence-based, and original examination of the effects of climate change on Alberta’s biodiversity
Understanding Climate Change Dynamics of Tree Species: Implications for Future Forests.
Resource
This book chapter addresses how future forests will be shaped, in large part, by tree responses to climate change via mortality, migration, and adaptation. The authors first demonstrate the strong...
Understanding Disturbance Thresholds and Opportunities to Achieve Better Outcomes for Boreal Caribou in Canada: A Primer
Resource
The Canadian Boreal Forest Agreement commits signatories to promote recovery of boreal caribou through regional caribou action planning across Canada. The following primer describes how the national...
Understory Forage on Seismic Lines
Resource
The paper by the fRI Research Caribou Program investigates seismic lines for their abundance of forage plants, which could attract predators of caribou such as bears as well as alternate prey for...
Unexpected Greening in a Boreal Permafrost Peatland Undergoing Forest Loss is Partially Attributable to Tree Species Turnover
Resource
This resource is available on an external database and may require a paid subscription to access it. It is included on the CCLM to support our goal of capturing and sharing the breadth of all...
Ungulate Occurrence in Forest Harvest Blocks is Influenced by Forage Availability, Surrounding Habitat, and Silviculture Practices - Summary
Resource
In Canada, the young forests created by harvesting have shifted the distribution and abundance of deer, elk, and moose. A consequence is unsustainable caribou predation by shared predators like bears...
Ungulate Occurrence in Forest Harvest Blocks is Influenced by Forage Availability, Surrounding Habitat, and Silviculture Practices
Resource
Forest harvesting causes habitat loss and alteration and can change predator– prey dynamics. In Canada, forest harvesting has shifted the distribution and abundance of ungulates (deer, elk and moose)...
Unravelling the Impacts of Disturbance Type and Regeneration on Movement of Threatened Species
Resource
Impact of disturbance on the daily movement of two large threatened mammals, and examined the nuances of movement response to type and regeneration of disturbance across seasons.
Untangling Effects of Human Disturbance and Natural Factors on Mortality Risk of Migratory Caribou
Resource
Abstract Human disturbances are rapidly increasing in northern and Arctic regions, raising concerns about the recovery and persistence of declining caribou ( Rangifer tarandus) populations. Yet, the...
Update of the Silvics of North America Project
Resource
A video presenting an update on the Silvics of North America Initiative. The Silvics of North America describes the silvicultural characteristics of hundreds of conifers and hardwoods in the US...
Update on NRCan ’s Progress Toward the Digitalization of the Forestry Sector
Resource
A video that highlights NRCan's progress towards digitalization of the forestry sector. Video includes on-the-ground examples from the Canadian perspective. A PDF of the PowerPoint presentation can be...
Update on the Global Status of Wild Reindeer and Caribou
