Early genetic selection for wood stiffness in juvenile Douglas-fir and western hemlock

Creator:: Urhan, Oguz S.
Abstract:: Wood modulus of elasticity (MOE), also known as wood stiffness, is one of the most important wood properties. Wood stiffness is a measure of the resistance to deflection, and is important because some products such as laminated veneer lumber, plywood, and dimension lumber require stiff and strong wood. Incorporating wood...

Interactions Between Wild Bee Communities and Douglas-fir Beetle (Dendroctonus pseudotsugae) Populations in Douglas-fir (Pseudotsugae menziezii) Forests of the Intermountain West

Creator:: Foote, Gabriel G.
Abstract:: This work combines both applied and basic research regarding previously undescribed relationships between two ecologically and economically important insect groups in coniferous forests, bark beetles (Coleoptera: Curculionidae, Scolytinae) and wild bee (Hymenoptera: Apiformes) communities in Western North America. Across the continent, native bark beetle outbreaks are key drivers of structural...

Physiological Responses of Loblolly Pine and Douglas-fir Seedlings from Various Provenances to Timing and Frequency of Drought Stress

Creator:: Mosel, Jamie E.
Abstract:: Drought is expected to increase in many parts of the world and has been shown to affect tree physiology and growth, with seedlings being particularly vulnerable. Seedling drought responses are often species dependent, and even within species different populations may demonstrate a spectrum of responses to drought, from susceptibility to...

Deer-mediated ecosystem service vs. disservice depends on forest management intensity - Dataset

Creator:: Stokely, Thomas D.
Abstract:: This dataset consists of planted crop-tree growth metrics (Pseudotsuga menziesii), non-crop tree vegetation metrics, and foraging data for black-tailed deer (Odocoileus hemionus columbianus) and Roosevelt elk (Cervus canadensis rooseveli) collected from the Intensive Forest Management experiment, Oregon Coast Range, USA, 2011-2016. The objective of the experiment was to quantify the...

Evaluating High Release Rate MCH (3-methylcyclohex-2-en-1-one) Treatments for Preventing Dendroctonus pseudotsugae (Coleoptera: Curculionidae) Infestations

Creator:: Brookes, Harrison M.
Abstract:: The Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins) can kill large numbers of Douglas-fir trees (Pseudotsuga menziesii (Mirbel) Franco) across a landscape during periods of population outbreaks. High-value individual trees and small stands can be protected from Douglas-fir beetle infestation during outbreaks by applying the anti-aggregation pheromone, MCH (3-methylcyclohex-2-en-1-one). MCH treatments are...

Relative competitive abilities of several common forest species and planted Douglas-fir in western Oregon

Creator:: Naylor-Murphy, Lanea
Abstract:: In terms of production forestry, more often than not any species that is not the crop species is considered a competitor as they are using finite growing resources that would otherwise be available to the crop species. With specific regard to Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) production in the Pacific...

Stem sapwood water transport and storage strategies in three conifers from contrasting climates

Creator:: Barnard, David M.
Abstract:: The state of Oregon has two distinct climate types bisected by the crest of the Cascade Mountain range. The western side of the Cascades experiences high levels of precipitation and mild temperatures due to the maritime influence of the Pacific Ocean, while the eastern side lies in the rain shadow...

Approaches for Characterizing Plant Physiological Responses to Environmental Stress

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...

A Multi-Spatial Scale Economic Analysis of the Impacts of Bear Damage to Douglas-fir on Private Timberlands in the Pacific Northwest

Creator:: Kline, Kristina N.
Abstract:: Black bears (Ursus americanus) in western Oregon and Washington peel bark from conifers in early spring to forage on the sugar-rich phloem and cambial tissues. This provides important energy at a time when similarly attractive forage is scarce. Bears often damage Douglas-fir (Pseudotsuga menziesii) trees in stands that are intensively...

Impacts of Swiss needle cast on Douglas-fir tree-ring stable isotopes and tree carbohydrate reserves

Creator:: Saffell, Brandy J.
Abstract:: Understanding the mechanisms of disease in forest pathology is a critical component to learning how to most efficiently manage tree diseases like Swiss needle cast (SNC). SNC is an economically important, fungal disease of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) that is prevalent in coastal areas of the Pacific Northwest. This...
