Adaptation of trembling aspen and hybrid poplars to frost and drought: implications for selection and movement of planting stock in western CanadaDownload
This study contains a series of experiments to evaluate growth performance and survival of hybrid poplars (Populus spp.) and trembling aspen (Populus tremuloides Michx.) in boreal planting environments in western Canada. Ecophysiological traits related to drought resistance and winter survival...
Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, CanadaDownload
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...
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...
This two papers thesis explores the economics of hybrid poplar plantations as a potential bioethanol feedstock in Canada. The first paper (Chapter 2) is the stand-level analysis of the financial viability of producing hybrid poplar on private lands for both single-stem and coppice production...
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...
•Intensive forestry systems and breeding programs often include either native aspen or hybrid poplar clones, and performance and trait evaluations are mostly made within these two groups. Here, we assessed how traits with potential adaptive value varied within and across these two plant groups....
Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In...
