The effects of chromated copper arsenate and ammoniacal copper zinc arsenate on shear strength development of phenolic resin to Sitka spruce bonds

Creator:: Prasad, T. R. Narayana, Humphrey, Philip E., and Morrell, Jeffrey J.
Abstract:: Preservative treatment of whole, wood-based composite products (mainly panels) has disadvantages; problems largely stem from swelling, strength loss, and incomplete or inappropriate penetration during treatment, and distortion during redrying. Pretreatment of comminuted wood prior to mat lay-up is one alternative, though the addition of chemicals may affect bonding during subsequent...

Can fuel-reduction treatments really increase forest carbon storage in the western US by reducing future fire emissions?

Creator:: Campbell, John L., Harmon, Mark E., and Mitchell, Stephen R.
Abstract:: It has been suggested that thinning trees and other fuel-reduction practices aimed at reducing the probability of high-severity forest fire are consistent with efforts to keep carbon (C) sequestered in terrestrial pools, and that such practices should therefore be rewarded rather than penalized in C-accounting schemes. By evaluating how fuel...

Using Landsat-derived disturbance history (1972–2010) to predict current forest structure

Creator:: Pflugmacher, Dirk, Cohen, Warren B., and Kennedy, Robert E.
Abstract:: Lidar is currently the most accurate method for remote estimation of forest structure, but it has limited spatial and temporal coverage. Conversely, Landsat data are more widely available, but exhibit a weaker relationship with structure under medium to high leaf area conditions. One potentially valuable means of enhancing the relationship...

Remote sensing of transpiration and heat fluxes using multi-angle observations

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Collatz, James G., Black, T. Andrew, Tucker, Compton J., Sellers, Piers J., and Grant, Nicholas
Abstract:: Surface energy balance is a major determinant of land surface temperature and the Earth's climate. To date, there is no approach that can produce effective, physically consistent, global and multi-decadal energy–water flux data over land. Net radiation (R[subscript n]) can be quantified regionally using satellite retrievals of surface reflectance and...

Effects of silvicultural practices on carbon stores in Douglas-fir – western hemlock forests in the Pacific Northwest, U.S.A.: results from a simulation model

Creator:: Harmon, Mark E. and Marks, Barbara
Abstract:: We used a new model, STANDCARB, to examine effects of various treatments on carbon (C) pools in the Pacific Northwest forest sector. Simulation experiments, with five replicates of each treatment, were used to investigate the effects of initial conditions, tree establishment rates, rotation length, tree utilization level, and slash burning...

Analysis of metal-plate-connected wood trusses with semi-rigid joints

Creator:: Gupta, R., Gebremedhin, K. G., and Cook, J. R.
Abstract:: Metal-plate-connected wood trusses with semi-rigid joints were investigated by the matrix method of structural analysis. The element-stiffness matrix and fixed-end forces of an individual member with one or both ends semi-rigid were derived as modifications of the idealized cases. The case of unequal elastic connections at two ends of a...

Applying the dual-isotope conceptual model to interpret physiological trends under uncontrolled conditions

Creator:: Barnard, H. R., Brooks, J. R., and Bond, B. J.
Abstract:: The inter-relationships among δ¹³C and δ¹⁸O in tree ring cellulose and ring width have the potential to illuminate long-term physiological and environmental information in forest stands that have not been monitored. We examine how within-stand competition and environmental gradients affect ring widths and the stable isotopes of cellulose. We utilize...

Effect of growth ring orientation and placement of earlywood and latewood on moe and mor of very-small clear Douglas-fir beams

Creator:: Grotta, A. T., Leichti, R. J., Gartner, Barbara L., and Johnson, G. R.
Abstract:: ASTM standard sizes for bending tests (either 50 × 50 mm or 25 × 25 mm in cross-section) are not always suitable for research purposes that characterize smaller sections of wood. Moreover, the ASTM standards specify loading the sample on the longitudinal-tangential surface. If specimens are small enough, then the...

Relating Forest Attributes with Area- and Tree-Based Light Detection and Ranging Metrics for Western Oregon

Creator:: Goerndt, Michael E., Monleon, Vicente J., and Temesgen, Hailemariam
Abstract:: Three sets of linear models were developed to predict several forest attributes, using stand-level and single-tree remote sensing (STRS) light detection and ranging (LiDAR) metrics as predictor variables. The first used only area-level metrics (ALM) associated with first-return height distribution, percentage of cover, and canopy transparency. The second alternative included...

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...
