Detection of an Invisible Foe: Annosus Root and Butt Rot
Resource
Annosus root and butt rot was first reported in Quebec in 1989. The causal fungus enters a pine stand by colonizing the surface of freshly cut stumps. The disease spreads through contact between the...
Detection of Coniferous Seedlings in UAV Imagery
Resource
Rapid assessment of forest regeneration using unmanned aerial vehicles (UAVs) is likely to decrease the cost of establishment surveys in a variety of resource industries. This research tests the...
Development of a Climate-Sensitive Structural Stand Density Management Model for Red Pine
Resource
The primary goal of this study was to develop a climate-sensitive modular-based structural stand density management model for red pine plantations situated within central North America. For a given...
Développement juvénile de 25 familles de pin blanc (Pinus strobus L.) issues de pollinisation libre en plantations mélangées avec l'aulne rugueux (Alnus incana)
Resource
There is renewed interest in the management of eastern white pine ( Pinus strobus L.) for high-quality wood production. Several tree improvement programs have been implemented for the last few decades...
Differences in Soil Fungal Communities between Forested Reclamation and Forestry Sites in the Alberta Oil Sands Region
Resource
Fungi play key roles in forest soils and provide benefits to trees via mycorrhizal symbioses. After severe disturbance, forest regrowth can be impeded because of changes in fungal communities. In 2013...
Differences in the Composition of Soils Under Open and Canopy Conditions at Two Sites Close-in to the Great Canadian Oil Sands Operation, Fort McMurray, Alberta
Resource
Soils sampled at sites 2.3 and 5.3 km south of the Great Canadian Oil Sands (GCOS) plant, Fort McMurray, respectively were found to differ statistically with reference to several macronutrients
Diseases of Black Spruce in Ontario
Resource
Over 70 diseases have been found and recorded on black spruce ( Picea mariana [Mill.] B.S.P.) in Ontario (Davis and Myren 1990). They range from vigorous pathogens capable of causing death or serious...
Does Dust from Arctic Mines Affect Caribou Forage?
Resource
A 2017 paper assessing the impacts of dust from a mining haul road in the NWT on vegetation used by caribou. The paper concluded that dust from the road negatively affected the vegetation within a...
Does Wood Mulch Trigger Microbially Mediated Positive Plant-Soil Feedback in Degraded Boreal Forest Sites? A Post Hoc Study
Resource
Introduction: Reforestation of degraded lands in the boreal forest is challenging and depends on the direction and strength of the plant-soil feedback (PSF). Methods: Using a gradient in tree...
Drivers and Impacts of the Record-Breaking 2023 Fire Season
Resource
A video outlining the major drivers and impacts of the record-breaking 2023 wildfire season in Canada. A PDF of the PowerPoint can be found here.
Early Successional Plant Community Dynamics on a Reclaimed Oil Sands Mine in Comparison With Natural Boreal Forest Communities
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...
Earth Observation for Improved Regulatory Decision Making in Alberta – Workshop Report
Resource
NRCan pilot science projects have proven that Earth Observation can provide relevant and valuable information to inform and enhance monitoring and support regulatory frameworks
Eastern Canadian Temperate Deciduous Forest
Resource
The Canadian National Vegetation Classification (CNVC) is an ecological classification of natural and semi-natural Canadian vegetation. The classification is a hierarchical taxonomy, describing...
Eastern North American Temperate Hardwood – Conifer Forest
Resource
The Canadian National Vegetation Classification (CNVC) is an ecological classification of natural and semi-natural Canadian vegetation. The classification is a hierarchical taxonomy, describing...
Ecological Bench-marking and Biomonitoring for Detection of Airborne Pollutant Effects on Vegetation and Soils
Resource
There was only very limited evidence of biological responses to increased pollutant content in spite of significantly higher pollutant levels in tissues close to existing industrial developments.
