Airborne Light Detection and Ranging (LiDAR) for Individual Tree Stem Location, Height, and Biomass Measurements

Creator:: Edson, Curtis and Wing, Michael G.
Abstract:: Light Detection and Ranging (LiDAR) remote sensing has demonstrated potential in measuring forest biomass. We assessed the ability of LiDAR to accurately estimate forest total above ground biomass (TAGB) on an individual stem basis in a conifer forest in the US Pacific Northwest region using three different computer software programs...

Is long primary growth associated with stem sinuosity in Douglas-fir?

Creator:: Gartner, Barbara L. and Johnson, G. R.
Abstract:: Stem sinuosity is a highly visible stem-form trait in the leaders of fast-growing Douglas-fir (Pseudotsuga menziesii var. (Mirb.) Franco) trees, yet its cause is unknown. We tested the hypotheses that sinuous stems have longer expanses of primary growth than nonsinuous stems (putting the leader at higher risk curvature, induction of...

Designing skid trail systems to reduce soil impacts from tractive logging machines

Creator:: Froehlich, Henry A., Aulerich, D. E., and Curtis, R.
Abstract:: Logging on skid trails restricted to 10 percent or less of the harvested stand can reduce the area of compacted soil by at least two-thirds, In a comparative study, productivity of Douglas-fir logs per hour was just as great In an area with designated trails as In an adjacent area...

Impact of the foliar pathogen Swiss needle cast on wood quality of Douglas-fir

Creator:: Johnson, G. R., Grotta, Amy T., Gartner, Barbara L., and Downes, Geoff
Abstract:: Many stands of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) near coastal areas of Oregon and Washington are heavily infected with the foliar pathogen causing Swiss needle cast (SNC) disease, and yet there is very little research on the resulting wood quality. Modulus of elasticity (MOE), modulus of rupture (MOR), microfibril angle...

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...

The market for waterfowl hunting on private agricultural land in western Oregon

Creator:: Rasker, Ray, Cleaves, David A., Johnson, Rebecca L., 1955-, and Oregon State University. Forest Research Laboratory
Abstract:: Trends in fee hunting in Oregon are examined, with particular emphasis on waterfowl in the western part of the state. Farmers with potential or existing waterfowl habitat in western Oregon were surveyed about their views on managing their lands for waterfowl. As incentives to such practices, they listed the financial...

Flexural tests of large glued-laminated beams made from visually graded hem-fir lumber

Creator:: Johnson, James W. and Oregon State University. Forest Research Laboratory
Abstract:: Fifteen large glued-laminated beams made from visually graded hem-fir lumber were designed, fabricated, and tested to failure in static bending. When tested, the beams had an average moisture content of 7.5 percent. The beams were 40 feet long, 5 1/8 inches wide and 24 inches deep. Before laminating, individual pieces...
