Temporal effect of vegetation management on growth and wood quality of conifers in a western Oregon plantation

Creator:: Goracke, Heidi S. Roe
Abstract:: Concern over the increasing proportion of juvenile wood grown in second growth plantations has led to a large amount of research on the effects of common silvicultural practices on wood quality. Lacking is research on the effect of timing and duration of vegetation control on wood quality near the pith...

Accuracy and suitability of several stand sampling methods in riparian zones

Creator:: Marquardt, Theresa
Abstract:: Stand structure in headwater riparian areas of western Oregon is highly variable making quantification of structural attributes within these stands difficult. A reliable sampling design is important to characterize and monitor changes in stand structure over time. This study examined sixteen alternatives for sampling live conifers and six alternatives for...

Comparing structure and development of Douglas-fir old-growth, plantations, and young natural forests in western Oregon

Creator:: Dowling, Christopher D.
Abstract:: Ages, diameter growth, density, tree size, and species were studied in old-growth, plantation, and young natural Douglas-fir stands in three areas in western Oregon: the western and eastern Coast Range and the western Cascades. The purpose was to compare the development of these three stand types and to determine whether...

The combined effects of vegetation control and seedling size class on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedling productivity on a site in Oregon

Creator:: Lefebvre, Robert F.
Abstract:: Controlling competing vegetation with the application of herbicides and increased seedling size at planting has been shown to increase seedling survival and growth. These two important reforestation tools have often been studied independently of each other, limiting comparisons that can be made between them. This study utilized a factorial treatment...

(Re)claiming forestry : a case study of women's empowerment

Creator:: Redmore, Lauren E.
Abstract:: Nonindustrial private forest (NIPF) owners control a significant portion of forestland nationwide. Even though women own or manage NIPF lands, we know very little about how women manage forestland and what barriers women face in forest management. In addition, while there are several forestry organizations available to NIPF owners, few...

The economics of carbon sequestration in western Oregon forests

Creator:: Im, Eun Ho
Abstract:: This study considered regional forest policies for sequestering carbon in existing forests in western Oregon. A model of log markets in western Oregon was employed to examine the impacts of forest policy changes on future carbon stock, harvests, and management activities. A carbon tax program, as a mitigation option for...

Mixed-Severity Fire Effects on Biological Legacies and Vegetation Response in Pseudotsuga Forests of Western Oregon's Central Cascades, USA

Creator:: Dunn, Christopher J.
Abstract:: Mixed-severity fire occurrence is increasingly recognized in Pseudotsuga forests of the Pacific Northwest, but questions remain about how tree mortality varies, and forest structure is altered, across the disturbance gradient observed in these fires. Therefore, we sampled live and dead biological legacies at 45 one ha plots, with four 0.10...

Twenty-five-year response of Larix occidentalis stem form to five stand density regimes in the Blue Mountains of eastern Oregon

Creator:: Lennette, Andrew P.
Abstract:: Upper-stem diameter measurements from a levels-of-growing-stock study on Larix occidentalis in the Blue Mountains of eastern Oregon were collected over a 25 year period with an optical dendrometer. The following hypotheses were tested with these data: 1) stand density regime has a significant effect on stem form; and 2) crown...

Trade-offs between management for fire risk reduction and northern spotted owl habitat protection in the dry conifer forests of southern Oregon

Creator:: Comfort, Emily Julia, 1974-
Abstract:: There is a perceived trade-off between fire risk reduction and northern spotted owl habitat protection in dry-conifer forests in southwestern Oregon. Management options for balancing this trade-off need to be sought at the landscape level. Applied landscape ecology suggests three important features to consider are (1) patch size and configuration...

Playing with pedagogy : a case study of contextual teaching and learning for the natural resources classroom

Creator:: Greene, Kim (Kimberly Kate)
Abstract:: This thesis investigates Contextual Teaching and Learning (CTL) as a method of instruction for natural resources education. The research follows the adoption of CTL in the K-12 classrooms of six teachers focusing on natural resources education at two rural schools in Western Oregon. CTL is being investigated because it connects...
