Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

Creator:: Acuna, Mauricio A.
Abstract:: There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

Within-stem variation of respiration in Pseudotsuga menziesii (Douglas-fir) trees

Creator:: Pruyn, Michele L., Gartner, Barbara L., and Harmon, Mark E.
Abstract:: • A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees. • Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...

Water relations and the root regeneration response of Douglas-fir

Creator:: Cobb, Cheryl Anne
Abstract:: The effect of lifting date and root-pruning treatments on water potential, root regeneration, and shoot growth of six-month-old and three-year-old Douglas-fir seedlings bare-root transplanted into a growth chamber, and sawdust bed, respectively, was studied. Root growth in six-month-old and three-year-old seedlings was highest in February and August respectively. Survival was...

Vegetation-environmental relationships on two clearcuts on the western slopes of the Oregon Cascades

Creator:: Egeland, Dawn M.
Abstract:: Douglas-fir and western hemlock growth and stocking were examined on two neighboring clear-cut watersheds in the Western Cascades of Oregon and related to the intensity of burning and logging disturbance, habitat type, soil type, aspect and the influence of percent cover of both invading Ceanothus species and residual Acer circinatum....

Ultrastructure of parenchyma and sclereids in Douglas-fir [Pseudotsuga menziesii(Mirb.)Franco] bark

Creator:: Dougal, Edward Francis
Abstract:: Because Douglas-fir [Pseudotsuga menziesii(Mirb.)Franco] bark is a raw material produced in our renewable forests along with wood, an understanding of the ultrastructure of bark cells is of paramount importance if wood technologists are to utilize the bark to the fullest potential. The objectives of this study were to develop microscopic...

Two studies of Acer macrophyllum : I. The effects of bigleaf maple on soils in Douglas-fir forests : II. The ecology of bigleaf maple seedling establishment and early growth in Douglas-fir forests

Creator:: Fried, Jeremy Steven
Abstract:: Bigleaf maple (Acer iaacrophyllunt) is a deciduous, persistent, sprouting species that frequently accounts for as much as 20% of the basal area in Douglas-fir forests. Because of the lack of knowledge of the role of bigleaf maple in Douglas-fir forest ecosystems and the problems that it poses as a vigorous...

Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...

The role of soil-water depletion and plant-moisture stress in soil classification and cambial activity of Douglas-fir

Creator:: Thomas, Byron R.
Abstract:: Relationships between soil-water stress and plant-moisture stress were studied with respect to soil classification and cambial activity in Douglas-fir. The study sites were forested with Douglas-fir and located in McDonald Forest and near Marys Peak in the Oregon Coast Range. Soil-water depletion was followed by the use of gypsum blocks...
