Natural regeneration of Douglas-fir in uneven-aged stands in southwest Oregon

Creator:: Gerstein, Jared M.
Abstract:: The response to various levels of stand density by natural Douglas-fir regeneration, shrub and sprouting hardwood species was studied in the mixed-evergreen-forests of southwest Oregon. Partial-cut old growth (harvested 22-31 years prior) and thinned evenaged (harvested 9-17 years prior) stand types were used as surrogates for intentionally managed uneven-aged stand...

Big huckleberry (Vaccinium membranaceum Dougl.) ecology and forest succession, Mt. Hood National Forest and Warm Springs Indian Reservation, Oregon

Creator:: Anzinger, Dawn
Abstract:: This thesis is an observational study that examines relationships between disturbance, forest stand development, and big huckleberry (Vaccinium membranaceum) fruit productivity and growth by combining ecological methods with the traditional ecological knowledge of Warm Springs ceremonial huckleberry pickers. Shrub fields of fruiting big huckleberry develop in early seral subalpine environments...

Spatial pattern and dynamics of hardwood patches in the Coast Range of Oregon, 1939-1993

Creator:: Hess, Rebecca Susan
Abstract:: Analysis of the long-term spatial pattern and dynamics of hardwood patches in the Coast Range of Oregon provides numerous ecological insights. Natural and anthropogenic disturbances have contributed to the development of a patchy mosaic of vegetation types in the area. Some hardwood patches in the Coast Range may be the...

Hydraulic properties of compression wood in branches and reoriented shoots of Douglas-fir (Psuedotsuga menziesii)

Creator:: Spicer, Rachel
Abstract:: Xylem anatomy is a strong determinant of water transport efficiency and is therefore an important component of the overall hydraulic strategy of any woody plant. However, in addition to its role in water transport, xylem also serves in mechanical support, and these two functions may represent conflicting design requirements. To...

Juniper utilization : issues of chemistry and management

Creator:: Swartley, D. Benjamin
Abstract:: Western juniper (Juniperus occidentalis) poses both a challenge and an opportunity for natural resource management in the rangelands of the northern Great Basin. The continued expansion of western juniper on the rangelands of the interior Northwest will likely continue as there are currently no practical options for returning this area...

Competitive interactions in young, coastal Douglas-fir/red alder mixtures : implications for wood quality

Creator:: Grotta, Amy T.
Abstract:: When Douglas-fir and red alder grow in mixture, interactions between the two species can be competitive, facilitative, or a combination of both over time. A number of factors have recently led to increased interest in managing these two species together for commercial production, and ongoing investigations are yielding important information...

Wood density patterns of young Costa Rican trees in planted and natural forests

Creator:: Baker, David C.
Abstract:: In plantation forestry, rapid growth rate is favorable for wood production, but may decrease wood density, which is an important indicator of wood quality for both pulp and solid wood products. I looked for (1) differences in radial patterns of wood density between planted and naturally grown Costa Rican tree...

Using oral histories to document changing forest cover patterns : Soap Creek Valley, Oregon, 1500-1999

Creator:: Zybach, Bob
Abstract:: This thesis examines forest history of a portion of the Douglas-fir Region: Soap Creek Valley, a 15,000 acre sub-basin of the Luckiamute River in northern Benton County, Oregon. The primary reasons for the research were to test oral history methodology, document sub-basin scale forest cover pattern changes, and determine basic...

Stand development after 20-years of growth in Douglas-fir and red alder mixtures

Creator:: Garrelts, Brennan T.
Abstract:: This study examines the long-term role of interference on stand development of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and red alder (Alnus rubra Bong.) planted mixtures in the Central Cascades of Oregon, USA. The two species are common associates in naturally regenerated and planted conifer stands in the Pacific Northwest. Due...

Exploring Novel Contrast Agents with Anthropomorphic Mesh Models in MCNP

Creator:: Garcia, Jacqueline K.
Abstract:: Breast cancer is the leading cancer in women with an estimated 13% of women in the United States developing a form of invasive breast cancer in her lifetime. The survival rate is estimated to be 85%, but the American Cancer Society estimates that early detection of breast cancer in the...
