An analysis of the import demand for hard red winter and western white wheat in Asian Pacific rim nations

Creator:: Simone, Mark V.
Abstract:: Wheat is a major agricultural product in the Pacific Northwest (PNW). The market class primarily grown in the region is Western White (WW) wheat. An important export market for PNW wheat producers is the Asian Pacific Rim (APR), due to its proximity and economic growth. Agronomic research has been conducted...

Ecophysiology of the cyanolichen Lobaria oregana

Creator:: Antoine, Marie E.
Abstract:: This thesis consists of three manuscripts describing ecophysiological research on the cyanolichen Lobaria oregana. The first manuscript includes a re-evaluation of the assumptions underlying past estimates of N fixation by this species and provides an estimate of annual N fixation at the Wind River Canopy Crane (WRCC). Based upon litterfall...

Effect of western juniper on understory herbage production in Central Oregon

Creator:: Vaitkus, Milda R.
Abstract:: Evidence suggests that western juniper (Juniperus occidentalis) in Central Oregon affects understory production and composition. As trees increase in size and density, understory production is reduced and composition changes. This study was designed to identify the relationship between production and composition of understory vegetation and various tree canopy sizes of...

Characteristics of forests at spotted owl nest sites in the Pacific Northwest

Creator:: Hershey, Kit
Abstract:: This study describes the composition and structure of forests within the immediate vicinity of Northern spotted owl (Strix occidentalis caurina) nest sites in the Klamath, Coast, and Cascade provinces of western Oregon and the Olympic province, Washington. I compared forest stand data collected at 105 nest sites with data from...

Habitat relationships of small terrestrial vertebrates and invertebrates in managed forests in the southern Oregon Cascades

Creator:: McDade, Kirsten Ayn
Abstract:: Silviculture systems that involve commercial thinning may provide higher quality wildlife habitat than traditional clearcut systems, yet such systems have not been vigorously tested. This prospective study examined forest floor animal abundance and habitat relationships under three different silviculture conditions: clearcuts, commercial thins, and uncuts. Eighteen stands, six per treatment,...

Interference dynamics in mixed red alder/Douglas-fir forests

Creator:: D'Amato, Anthony W.
Abstract:: This study characterized the nature and dynamics of interference in mixed red alder (Alnus rubra Bong.)/Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) stands in the Pacific Northwest, USA. Long-term spatial and tree measurements from the Cascade Head (CH) and H.J. Andrews (HJA) Experimental Forests in western Oregon and Delezene Creek (DC), Washington...

Watershed-level patterns among stream amphibians in the Blue River watershed, West-Central Cascades of Oregon

Creator:: Hunter, Matthew G.
Abstract:: Most recent research on stream amphibians in the Pacific Northwest has focused on associations with reach-level or stand-level environmental features. Little is known about landscape-level distributions of these species or landscape-level aspects of their life-histories. I used a watershed-wide sample and logistic regression to develop models and maps of probability...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

Comparison of Phellinus weirdi root rot damage in a 60-year-old Douglas-fir (Pseudotsuga menziesii) stand with the damage in the preceding old-growth stand

Creator:: Tkacz, Borys M.
Abstract:: Laminated root rot of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) caused by the fungus Phellinus weirii (Murr.)Gilbertson was studied in two successive stands in the Oregon Coast Range. Damage due to the disease in a 60-year-old second-growth stand was compared with incidence in the preceding 300-year-old stand on the same site....

Sediment routing in a small watershed in the blast zone at Mount St. Helens, Washington

Creator:: Smith, Richard D. (Richard Dean), 1950-
Abstract:: A descriptive model of the routing of sediment that was delivered to the study area by the 1980 eruptions of Mount St. Helens has been developed. On hillslopes this sediment was distributed among three major storage compartments: 1) the tephra profile, 2) primary storage, and 3) secondary storage. The most...
