Assessing operational silviculture and modeling juvenile growth in Saskatchewan white spruce (Picea glauca (Moench) Voss) plantations
DownloadFall 2015
White spruce (Picea glauca (Moench) Voss) plantations are often established with mechanical site preparation and tending. These silvicultural treatments encourage plantation survival and can influence growth, composition, and yield. To assess operational silviculture and model managed stand...

Assessing the vulnerability of rare plants using climate change velocity, habitat connectivity and dispersal ability
DownloadFall 2015
Climate change generally requires species to migrate northward or to higher elevation to maintain constant climate conditions, but migration requirement and migration capacity of individual species can vary greatly. Individual populations of species occupy different positions in the landscape...

Assisted migration to address climate change: recommendations for reforestation in western Canada
DownloadFall 2011
A changing climate is the largest threat to forest productivity in western Canada and to the ability of forested landscapes to provide ecological and economic services, both now and in the future. As climate changes, locally adapted tree populations become mismatched with local conditions,...

Cultivating Place, Livelihood, and the Future: An Ethnography of Dwelling and Climate in Western Greenland
DownloadSpring 2013
In order to investigate how Inuit Greenlanders in western Greenland are experiencing, responding to, and thinking about recent allegedly human-induced climate change, this dissertation ethnographically examines the lives of Greenlanders as well as Norse and Danes in the course of past historical...

Fall 2010
Bioclimate envelope models are widely used to project potential species habitat under changing climate. Conceptually, these models are also well suited to match natural resource management practices to new climatic realities, for example by guiding species choice in reforestation programs....

Investigating Fire as a Silvicultural Tool for Regeneration of Mountain Pine Beetle-killed Serotinous Pine of Northern Alberta
DownloadSpring 2016
Serotinous pine forests in Western Canada are threatened by a record-breaking mountain pine beetle (Dendroctonus ponderosae; MPB) outbreak - the largest recorded in Western North America. Forest managers are concerned with whether these closed-cone MPB-killed forests will successfully regenerate....

Long-Term Impacts of Commercial Thinning and Nitrogen Fertilization on Lodgepole Pine: A Two-Decade Analysis of Growth and Temporal Dynamics
DownloadFall 2023
Commercial thinning and fertilization are potential silvicultural tools to enhance Alberta’s Forest productivity in an imminent timber supply gap. In 2000, an experiment was initiated in a 68-year-old lodgepole pine stand located in Alberta’s upper foothills, using a 2x6 factorial design....

Fall 2015
Given high levels of human disturbance and projected rates of climate change, many species will be unable to keep pace with their shifting climatic ranges and thus face increased risk of extinction. This research investigated the use of assisted migrations for two rare and range-restricted plant...

Physiological, ecological and environmental factors that predispose trees, stands and landscapes to infestation by tree-killing Dendroctonus beetles
DownloadSpring 2013
In the last century the frequency and severity of outbreaks of tree-killing Dendroctonus beetles (Coleoptera: Curculionidae) have increased. Small-scale drivers within trees likely drive outbreak dynamics across landscapes. At a small scale, variation in carbohydrate availability within the stems...

Tree population responses to extreme climate events to guide reforestation under climate change
DownloadSpring 2018
As climates warm and extreme climatic events occur with more frequency and severity, maintaining forest health and productivity may involve planting seed sources from warmer, drier areas. To guide such reforestation strategies, this work analyzes the risks of both climate change and assisted...
