Laboratory decay resistance of preservative-treated red alder

Mitchoff, M. E.; Morrell, Jeffrey J. (Society of Wood Science and Technology, 1988-07)

Alder represents an abundant but underutilized resource that has little natural resistance to decay. Treated alder might be used for stakes, posts, or other nonstructural applications. The performance of alder treated wi ...
Land cover at northern spotted owl nest and non-nest sites, east-central Coast Ranges, Oregon

Perkins, John P. (John Phillip) (2000-05-25)

This study examined the differences, at various scales, between northern spotted owl (Strix occidentalis caurina) nest sites and non-nest sites, i.e., sites where no nests were found during surveys, in the Coast Ranges o ...
Land ownership and forest cover in the Oregon Coast Range : spatial pattern and social ground-truthing

Stanfield, Brooks J. (Brooks Jameson) (2000-09-11)

We use qualitative and quantitative methods to explore social and spatial relationships between land ownership and forest cover in the Oregon Coast Range. Using a Geographic Information System (GIS) and regression anal ...
A land use history of Benton County, Oregon

Longwood, Franklin Russell (1940-06)
The land-water interface : patterns of riparian vegetation and channel morphology in the Oregon Coast Range system

Takahashi, Mayumi (2003-07-17)

This study was conducted to describe variation of riparian vegetation in an Oregon Coast Range system according to geomorphic characteristics and in relation to streamflow. Specific objectives of this study were to: I) ...
Landscape characteristics and coho salmon (Oncorhynchus kisutch) distributions: explaining abundance versus occupancy

Steel, E. A.; Jensen, D. W.; Burnett, K. M.; Christiansen, K.; Firman, J. C.; Feist, B. E.; Anlauf, K. J.; Larsen, D. P. (NRC Research Press (Canadian Science Publishing), 2012-03)

Distribution of fishes, both occupancy and abundance, is often correlated with landscape-scale characteristics (e.g., geology, climate, and human disturbance). Understanding these relationships is essential for effective ...
The landscape ecology of secondary tropical forest in montane Costa Rica

Helmer, Eileen Hoey (1998-10-09)

Previous difficulties mapping tropical forest successional stage with satellite imagery may be one of the reasons why little is known about what socioeconomic and biophysical factors control tropical secondary forest pat ...
Landscape Management Policy Simulator (LAMPS) : version 1.1 : user guide

Bettinger, Pete, 1962-; Lennette, Marie; Oregon State University. Forest Research Laboratory (Corvallis, OR : Oregon State University, College of Forestry, Forest Research Laboratory, 2004)
Landscape patterns of pre-logging forest conditions in western Oregon

Rasmussen, Mary C. (1996-07-30)

Using historical maps and tools provided by GJS, the spatial patterns of pre-logging forest conditions were quantified for three landscapes in western Oregon. The spatial coincidence between forest patches and topograp ...
A landscape-scale analysis of vegetation recovery at Mount St. Helens

Lawrence, Rick L. (1998-01-14)

I used satellite remote sensing to examine the key factors controlling the natural revegetation of Mount St. Helens since its eruption in 1980. The study required three stages: determining the amount of vegetation presen ...
Large Predators Limit Herbivore Densities in Northern Forest Ecosystems

Ripple, William J.; Beschta, Robert L. (Springer, 2012)

There is a lack of scientific consensus about how top-down and bottom-up forces interact to structure terrestrial ecosystems. This is especially true for systems with large carnivore and herbivore species where the effe ...
Large woody debris and channel morphology of undisturbed streams in southeast Alaska

Robison, E. George (1987-09-30)

The characteristics and interactions of the riparian stand, large woody debris (LWD), and channel morphology were examined on five undisturbed, low gradient streams in southeast Alaska. One first-, two second-, one th ...
Lateral bearing strength of fasteners in lumber-plywood joints treated with fire retardants

Johnson, James W.; Oregon State University. Forest Research Laboratory (Corvallis : Forest Research Laboratory, School of Forestry, Oregon State University, 1976-02)
Lateral force resisting pathways in log structures

Scott, Randy J. (2003-04-14)

In recent years, log structures have been marketed as an alternative to conventional light-frame wood structures. Log structures are constructed using round timbers (or manufactured timbers) that are stacked vertically ...
Lead-user research in the wood window value chain

Kamke, Kathryn Jean (2009-07-08)

Lead-user research is a relatively new marketing research technique, and it has not seen much use in the forest sector. Lead-user research is designed to capture not just the needs of the customer in their own voice but ...
Leaf area index and productivity in eastern Washington forests

McCandlish, Brooks (1980-07-29)

The relationship between Leaf Area Index (LAI) and current stem-wood production was examined in selected stands in eastern Washington. Stands were sampled with an angle gauge (prism). LAI was estimated from sapwood ar ...
Leaf area index and specific leaf weight : keys to interpreting canopy photosynthesis and stand growth

Oren, Ram (1984-09-25)

Two physiological factors are of major importance to tree and stand growth: (1) the photosynthetic rate of foliage and (2) the amount of foliage. If carbohydrate allocation patterns remain constant, stand growth should b ...
Leaf litter chemistry and decomposition in a Pacific Northwest Coniferous forest ecosystem

Valachovic, Yana S. (1998-04-10)

The effects of initial leaf litter chemistry of 16 common coniferous and deciduous hardwoods and shrubs on their annual decomposition patterns were studied on the H.J. Andrews Experimental Forest (Oregon). Leaf litters w ...
Leaf litter chemistry controls on decomposition of Pacific Northwest trees and woody shrubs

Valachovic, Y.S.; Caldwell, B.A.; Cromack Jr., K.; Griffiths, Robert P. (NRC Canada, 2004-10)

The effects of initial leaf litter chemistry on first-year decomposition rates were studied for 16 common Pacific Northwest conifers, hardwoods, and shrubs at the H.J. Andrews Experimental Forest in western Oregon. Leaf ...
Leaf resistance responses in selected conifers interpreted with a model simulating transpiration

Running, Steven William (1973-08-07)

The resistance of a leaf to molecular gaseous diffusion is an important physiological response. Control of leaf resistance enables a plant to control its transpired water loss and regulates photosynthesis. Four study ...
