Creator:: Joo, Sukhyun
Abstract:: Estimating volume gains in genetically improved stands at rotation age is challenging because first-generation progeny tests in Douglas-fir were typically established to measure the relative growth performance of individual trees from open-pollinated parent trees. The overall goal of this dissertation research was to improve growth simulation of genetically improved Douglas-fir...

Full Text:: Title: Simulating Effects of Genetic Tree Improvement on Growth and Yield of Coastal Douglas-fir

Creator:: Osborne, Nathaniel L.
Abstract:: Forest growth and yield models are critical to supporting decision making in forestry, but often lack considerations for wood properties. The feasibility of simulating wood properties in the context of a Douglas-fir individual tree growth and yield model was evaluated. This assessment explored the effect of predicted sapwood width, stem...

Full Text:: Context of a Growth and Yield Model for Planted Douglas-fir Abstract approved

Creator:: Dinger, Eric J.
Abstract:: Three studies were conducted to characterize and present early-seral competition between Douglas-fir seedlings and the surrounding vegetation communities during Pacific Northwest forest establishment. The first experiment served as the foundation for this dissertation and was designed to quantify tradeoffs associated with delaying forest establishment activities by introducing a fallow year...

Full Text:: Mechanisms Influencing Douglas-fir Seedling Growth, Vegetation Community Development, and Physiology of

Creator:: Marias, Danielle E.
Abstract:: It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...
