Determination of relative economic weights for multitrait selection in coastal Douglas-fir

Creator:: Aubry, Carol A., Adams, W. T., and Fahey, Thomas D.
Abstract:: Abstract: Relationships between tree traits and tree value for lumber production were investigated. For the purposes of estimating relative economic weights for use in multitrait selection in coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii), tree height, diameter at breast height, and branch diameter were measured on 164 trees (ages...

Incorporation of nitrogen from decomposing red alder leaves into plants and soil of a recent clearcut in Oregon

Creator:: Swanston, Christopher W. and Myrold, David Douglas
Abstract:: Nitrogen incorporation from red alder (Alnus rubra Bong.) into an Oregon upland mesic forest soil was studied by tracing the fate of 15N added as 15N-labeled alder leaf litter. The recovery of 15N in vegetation, litter, light- and heavy-fractions of the soil, the chloroform-labile (microbial biomass) pool, and the whole...

Respiration, nitrogen fixation, and mineralizable nitrogen spatial and temporal patterns within two Oregon Douglas-fir stands

Creator:: Hope, Sharon M. and Li, Ching-Yan
Abstract:: Substrate respiration, mineralizable nitrogen, and nitrogen fixation rates, substrate moisture content, and temperature were measured in trenched and undisturbed plots within two western Oregon Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands. The stands represent two different environments and ages. Woods Creek, the site of the lower elevation mature 70-year-old stand, is...

Clonal expansion and seedling recruitment of Oregon grape (Berberis nervosa) in Douglas-fir (Pseudotsuga menziesii) forests: comparisons with salal (Gaultheria shallon)

Creator:: Huffman, David W. (William), 1962- and Tappeiner, John C.
Abstract:: Seedling regeneration and morphology of Oregon grape (Berberis nervosa Pursh) and salal (Gaultheria shallon Pursh) were studied in thinned and unthinned Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the central Coast Range, Oregon. Above- and below-ground growth of both species were significantly and negatively correlated with stand density. Oregon grape...

Stumps fumigated with chloropicrin: effects on surrounding plants

Creator:: Luoma, Daniel L. and Thies, Walter G.
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stumps, both healthy and infected by Phellinus weirii (Murr.)Gilbertson, were fumigated with chloropicrin at a clearcut site on Washington s Olympic Peninsula. Vegetation cover on plots adjacent to treated and untreated stumps was evaluated to determine fumigant effects on vascular plants and moss. Ninety-eight vascular...

Detecting landscape changes in the interior of British Columbia from 1975 to 1992 using satellite imagery

Creator:: Sachs, Donald L., Sollins, Phillip, and Cohen, Warren B.
Abstract:: To consider the regional scale effects of forest management requires complete and consistent data over large areas. We used Landsat Thematic Mapper and Multispectral Scanner (TM and MSS) imagery to map forest cover and detect major disturbances between 1975 and 1992 for a 4.2 x 106 ha area of interior...

Genetic variation in cold hardiness of Douglas-fir in relation to parent tree environment

Creator:: Balduman, Lisa M., Aitken, S. N., Harmon, M., and Adams, W. T.
Abstract:: The extent to which parent trees within breeding zones of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) are locally adapted to their native environments was evaluated. Forty families from each of one Coastal and one Cascade breeding population in Oregon were assessed for cold hardiness and growth phenology, and...

Modeling the incidence and severity of hemlock dwarf mistletoe in 110-year-old wind-disturbed forests in Southeast Alaska

Creator:: Trummer, L. M., Hennon, P. E., Hansen, E. M., and Muir, P. S.
Abstract:: A model was developed to predict the severity of dwarf mistletoe (Arceuthobium tsugense (Rosendahl) G.N. Jones) in western hemlock trees (Tsuga heterophylla (Raf.) Sarg.) that developed within forests of Southeast Alaska that experienced near-catastrophic windthrow in the late 1800s. The model suggests that the degree of dwarf mistletoe severity on...

Structure and yield of two-aged stands on the Willamette National Forest, Oregon: implications for green tree retention

Creator:: Acker, Steven A., Zenner, E. K., and Emmingham, W. H.
Abstract:: Green tree retention, a practice based on ecosystem science, has been integrated into forest management as a working hypothesis, requiring research and monitoring to quantify its effects. We undertook a retrospective study of natural, two-aged forest stands on the Willamette National Forest to provide preliminary estimates of the effects of...

Predicting branch diameters on second-growth Douglas-fir from tree-level descriptors

Creator:: Maguire, Douglas A., Johnston, Stuart R., and Cahill, James M.
Abstract:: The quality of lumber and veneer recovered from logs of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is directly influenced by the maximum limb size attained on the crop tree. Because limb sizes are influenced by standdensity regimes, a need has arisen for quantitative tools that link a wide array of silvicultural...

Abstract:: Seedlings of western redcedar (Thuja plicata Donn ex. D. Don), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were transplanted into soils with low and high levels of available NO3 – (and total N). Current-year foliage was sampled after 10 weeks to determine the effect of...

Vanadium in foraminiferal calcite as a tracer for changes in the areal extent of reducing sediments

Creator:: Hastings, David W., Emerson, Steven R., and Mix, Alan C.
Abstract:: We have used the vanadium concentration in cleaned foraminiferal calcite as a tracer of seawater V changes in the past. Since the benthic flux of vanadium is sensitive to the redox potential of sediments, changes in the vanadium concentration of seawater should be a reflection of changes that control the...

Oblique strike-slip faulting of the central Cascadia submarine forearc

Creator:: Goldfinger, Chris, Kulm, LaVerne D., Yeats, Robert S., McNeill, Lisa, and Hummon, Cheryl
Abstract:: At least nine WNW trending left-lateral strike-slip faults have been mapped on the Oregon-Washington continental margin using sidescan sonar, seismic reflection, and bathymetric data, augmented by submersible observations. The faults range in length from 33 to 115 km and cross much of the continental slop. Five faults offset both the...

Listric normal faulting on the Cascadia continental margin

Creator:: McNeill, Lisa C., Piper, Kenneth A., Goldfinger, Chris, Kulm, LaVerne, and Yeats, Robert S.
Abstract:: Analysis of multichannel seismic reflection profiles reveals that listric normal faulting is widespread on the northern Oregon and Washington continental shelf and upper slope, suggesting E-W extension in this region. Fault activity began in the late Miocene and, in some cases, has continued into the Holocene. Most listric faults sole...

Abstract:: Models of magnetic and gravity anomalies along two E-W transects offshore central Oregon, one of which is coincident with a detailed velocity model, provide quantitative limits on the structure of the subducting oceanic crust and the crystalline backstop. The models indicate that the backstop-forming western edge of the Siletz terrane,...
