Competition Impacts on Hybrid Poplar and Implications for Alternative Establishment Systems
DownloadSpring 2015
The effects of different vegetation control practices on tree-weed interactions and associated establishment and early tree growth were investigated in 1-3 year old hybrid poplar plantations containing Walker poplar (Populus deltoides x (P. laurifolia x P. nigra)) and its progeny Okanese poplar...

Red alder (Alnus rubra [Bong.]), is the most common hardwood species along the Pacific Northwest coast and is widely distributed as a component of mixed stands with conifers on highly productive sites. It is also a strong competitor in young conifer stands and rapidly overtops associated juvenile...

Evaluating trembling aspen seedling stock characteristics in response to outplanting and competition
DownloadFall 2017
Trembling aspen is commonly used in the afforestation of boreal forest reclamation sites; however, the presence of vegetation competition can reduce growth and establishment success. This research examines how initial morphological characteristics influence the above and belowground growth of...

Hybrid poplar plantations have the potential to produce large amounts of biomass for the forest industry, but the young trees are sensitive to competition. This research attempted to quantify the influence of factors regulating competition in hybrid poplar plantations under four years old. The...

Local-Scale Drivers of Spatial Patterns and Demographic Rates of Conifer Species in a Forest Chronosequence in Coastal British Columbia
DownloadSpring 2017
Growth, mortality and recruitment are the fundamental demographic processes driving changes in forest structure and dynamics. Rapid changes observed in many forests globally have imposed serious threats to ecosystem services such as carbon sequestration, biodiversity and hydrology, emphasizing...

Fall 2013
The Earth’s forests are of great economic, ecological, and social importance, and sustaining them is paramount for mitigating climate change. To successfully sus- tain forests we must understand their internal demographic dynamics and their relationship to climate. In this thesis, I developed...

Roots in reconstructed soils - how land reclamation practices affect the development of tree root systems
DownloadSpring 2018
Tree root systems are incredibly complex organs that fulfill several vital functions, the main ones being anchorage and uptake of water and mineral elements. They perform these functions in a highly complex and challenging soil environment with heterogeneously distributed soil resources, physical...

Spatial and Temporal Variations in Tree Growth, Mortality, and Biodiversity in Alberta Forests
DownloadSpring 2014
Understanding the spatial and temporal variation of tree demographic rates and biodiversity is essential for predicting the dynamics of forest ecosystems and their responses to changing environments. This thesis contributes to that understanding through modeling the long-term change in tree...
