Effects of community structure on aboveground net primary productivity (aNPP), leaf area index (LAI) and light use efficiency (LUE) in a boreal mixedwood forest of central Alberta, Canada.
DownloadFall 2018
Management practices, such as the use of herbicides to reduce abundance of deciduous and herbaceous vegetation can have dramatic influences on community structure and composition in regenerating boreal ecosystems. The vertical structure of boreal stands includes different functional groups:...

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 establishment of species with a range of shade tolerance within a strip shelterwood in the Interior Cedar Hemlock Zone of British Columbia
DownloadFall 2020
Strip or group shelterwood and other continuous cover forestry practices are commonly advocated for managing mixed species forests of Interior-Cedar Hemlock (ICH) Biogeoclimatic zone in British Columbia. In strip-shelterwood systems, narrow openings are created in the canopy to facilitate...

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 and Assessing the Yield Implications of Forest Canopy Gaps in Forest Management Using Full Feature LiDAR
DownloadSpring 2015
Gaps in the forest canopy are common in boreal aspen, spruce and mixedwood stands and can negatively affect forest volume. Data from four Alberta Vegetation Inventory (AVI) polygons, two aspen (Populus tremuloides) and two white spruce (Picea glauca), were analysed to determine how forest volume...

Reconstructed height growth trajectories of white spruce (Picea glauca) following deciduous release
DownloadSpring 2012
My study evaluated the “true” white spruce (Picea glauca [Moench] Voss) height growth potential in sites released from deciduous competition. Stem analysis, plus re-measurement data from 60 and 80-year-old trials were used. Interpolated site index (SI, height at breast height age 50) of released...

Stockability, relative density and productivity: investigating their link in boreal mixedwoods
DownloadSpring 2014
I explore and evaluate the use of indicators of density and stand composition in analyzing key aspects of the dynamics of boreal stands comprised primarily by trembling aspen (Populus tremuloides Michx.) and white spruce (Picea glauca (Moench) Voss. in western Canada. First, using repeated...

Fall 2016
Understory protection harvesting in boreal mixedwoods, which removes mature trembling aspen (Populus tremuloides Michx.) while leaving advance regeneration of white spruce (Picea glauca (Moench) Voss), is being used in many parts of northern Alberta, Canada. The harvesting system is a step...
