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...

Crown Architecture, Wood Stiffness and the Pipe Model Theory for White Spruce [Picea glauca (Moench) Voss] and Aspen (Populus tremuloides Michx.)
DownloadFall 2015
In forestry, the wood fibre supply chain describes the integration of harvesting operations, raw material transformation and end-product marketing. The forest industry may achieve an overall greater return on investment by developing a supply chain which incorporates measures of wood quality. The...

Defining roles for SHORT VEGETATIVE PHASE/AGAMOUS-LIKE 24-like (SAL) genes in the activity-dormancy transitions of white spruce (Picea glauca) terminal buds
DownloadSpring 2018
An important part of the annual growth cycle of white spruce (Picea glauca [Moench.] Voss; Pg) trees is the transition from active growth to dormancy, which confers protection against the potentially destructive environmental elements of winter. Terminal bud formation and cessation of meristemic...

Site index is widely used as a measure of forest site productivity, and is an essential input into growth and yield models forecasting forest stand development. However, accurate estimates of site index are frequently difficult or even impossible to obtain, particularly in the boreal mixedwoods...

Growth and yield implications of site preparation, competition control, and climate in the western boreal forest
DownloadSpring 2011
The main goal of this thesis was to improve our understanding of the long-term effects of establishment treatments and climate change on lodgepole pine and white spruce growth in the western boreal forests. My dissertation also investigated the combined effects of climate and competition on white...

Growth of understory spruce following mountain pine beetle attack and recalibration and validation of the Mixedwood Growth Model for black spruce
DownloadFall 2018
Effective forest management requires reliable growth and yield models and adequate information on changes in the forest resulting from climate change, insect outbreak and competition from neighboring trees. Growth responses of white spruce (Picea glauca (Moench) Voss) and black spruce (Picea...

Identifying historical climate-growth limitations of white spruce (Picea glauca) populations across North America
DownloadSpring 2021
Climate change may cause reduced forest productivity and higher tree mortality due to water deficits that result from increased evapotranspiration. Such limitations may occur in some areas of the North American boreal forest, where precipitation is low and warming trends are high. This thesis...

Improving forb establishment and restoring soil function in disturbed landscapes: Hitchhiking native forbs with white spruce
DownloadSpring 2018
Changing requirements for land reclamation in Alberta has led to the need for revegetation of disturbed lands with native woody and herbaceous species. Our study involves âHitchhiker Plantingâ which is similar to companion cropping in agriculture, with the goal of improving native forb...

Influence of variable retention and deadwood characteristics on saproxylic beetles in boreal white spruce stands
DownloadSpring 2016
Retention forestry aims to maintain a significant level of continuity in forest structure, composition and complexity so as to support conservation and recovery of biodiversity and ecological function on managed landscapes; however, the amount and distribution of retention that best meets...

Life history strategies of northern form Dolly Varden (Salvelinus malma malma) in the western Canadian Arctic
DownloadFall 2017
Northern form Dolly Varden char (Salvelinus malma malma) inhabit cold-water streams in the western Canadian Arctic. They are an important cultural and subsistence resource to local Aboriginal communities, yet little is known about their complex early life histories. Populations of Dolly Varden...
