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...
Determining the Importance of Grizzly Bear Predation on Central Mountain Caribou Populations: Final Report
Resource
To gain a better understanding of possible impacts of grizzly bears on central mountain caribou populations, we investigated three separate but inter-related topics concerning grizzly bear predation...
Determining the Importance of Grizzly Bear Predation on Southern Mountain Caribou Populations
Resource
The goal of this project is to determine to what extent grizzly bear predation might be influencing caribou populations in west-central Alberta. We use existing datasets supplemented with additional...
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
Dimensionnement de la chaîne nationale d’approvisionnement en semences du Canada : Évaluation préliminaire sur les arbres et arbustes
Resource
In 2021-2022, the National Tree Seed Centre led a series of surveys to establish an accurate idea of genetically appropriate seed supply for forest landscape restoration (FLR) needs across Canada by...
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...
Disturbance Zones of Influence on Boreal Songbird Communities in Northeastern Alberta
Resource
Canada’s boreal forest is important habitat for many North American birds, which play a vital role in the health of forests, and provide ecosystem services. Expanding human development in northern...
Divergent Patterns of Understory Forage Growth After Seismic Line Exploration: Implications for Caribou Habitat Restoration
Resource
Using field data from 351 seismic lines across [Alberta], and focusing on forage taxa preferred by moose and bears, we [investigated the effects of seismic line clearing on forage and resilience]
Do Oil and Gas Activities and Access Control Measures Affect the Distribution, Abundance and Movements of Grizzly Bears?
Resource
To understand how oil and gas activities and access control measures, particularly gates, influences grizzly bears and their habitats in Alberta, we used multiple data sources including spatial layers...
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...
