Using Remote Sensing and Process-based Growth Modeling to Predict Forest Productivity Across Western Oregon

Creator:: McAdam, Erick
Abstract:: Accurate measurement of forest productivity is fundamental to understand the carbon balance of forested ecosystems. Recent changes in climate highlight the importance of developing methods to measure forest productivity so that sound economic and environmental decision can be made. Efforts to measure forest productivity across the landscape using remote sensing...

Impact of insects on seed production in a Douglas-fir seed orchard in Oregon

Creator:: Dombrosky, Scott A.
Abstract:: The impact of various factors on seed production in a Douglas-fir (Pseudotsuga menziesii) seed orchard in western Oregon was examined by monitoring the fate of seeds in thirty cones, stratified into three crown levels, on each of ten trees during the 1984 growing season. Cones were examined monthly between April...

Enhancement of biological control for postharvest diseases of pear

Creator:: Benbow, Jesse M.
Abstract:: Yeast biocontrol agents that were applied to 'Bose' and 'Anjou' pears in the field up to three weeks prior to harvest were found to survive on the fruit at high population levels on both pear varieties. Cryptococcus infirmo-miniatus, Cryptococcus laurentii, and Rhodotorula glutinis maintained populations averaging 5 x 10⁶ cfu/fruit...

Photogrammetric uses of a new-generation analytical stereoplotter in forestry

Creator:: Kiser, James D. (James Donald)
Abstract:: The development of personal computer software coupled to an analytical stereoplotter allows major gains in efficiency and accuracy in a number of forestry related subjects. This thesis describes the operation of a system developed by Carto Instruments. This thesis demonstrates how area estimates might be made in a systematic way...

Water relations, growth and survival of root-wrenched Douglas-fir seedlings

Creator:: Duryea, Mary L.
Abstract:: Chapter 1 Growth and Survival of Root-Wrenched Douglas-fir Seedlings Root wrenching of seedlings (severing the roots 15 cm below the soil surface) was investigated as a nursery practice to improve growth and survival of field-planted Douglas-fir from six local seed sources in the Pacific Northwest. At lifting, shoots of wrenched...

Value, volume, and jobs : a comprehensive assessment of wood fiber and residue utilization within Oregon: 1992

Creator:: Ross, Janet R.
Abstract:: Oregon's forest product industry continues to be the nation's number one producer of wood products. The forest products industry contributes significantly to Oregon's economy. Changes in timber supply, land use policy, technology, and product demand create significant impacts on the region. The activities of the wood products industry translate into...

Taper, crown, and volume responses of a coastal Oregon Douglas-fir stand to sulfur treatments for control of Swiss needle cast

Creator:: Younger, Nicole L.
Abstract:: For nearly two decades, foresters in the Oregon Coast Range have been witnessing a substantial decease in Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco.) vigor and growth, caused by Swiss needle cast (Phaeocryptopus gaeumannii). Currently, no solutions are in sight but aerially-applied sulfur may alleviate Swiss needle cast and its...

Forest Response to Water Availability and Disturbance in the Western United States

Creator:: Berner, Logan T.
Abstract:: Earth’s atmosphere is unequivocally warming due to CO₂ and other greenhouse gas (GHG) emissions from human activities and this is having widespread impacts on forest ecosystems that provide important services to human societies. Forest ecosystems help regulate atmospheric CO2 concentrations by sequestering carbon in tree biomass and soils, which is...

Vertical structure and aboveground biomass of tropical forests from lidar remote sensing

Creator:: Gonçalves, Fabio Guimarães
Abstract:: Methods for obtaining accurate, spatially explicit estimates of biomass density in tropical forests are required to reduce uncertainties in the global carbon cycle, and to support international climate agreements and emerging carbon markets. Three-dimensional (3-D) remote sensing techniques sensitive to the vertical structure of vegetation provide a unique opportunity for...

Fluoride sorption and dissolution reactions in soils

Creator:: Peek, Daniel C.
Abstract:: The reaction of F, often a component of industrial wastes and phosphatic fertilizers, with soil was studied with regard to sorption reactions and resultant changes in solution composition. Sodium fluoride solutions (0.0 to 2.5 mmol/L F) were equilibrated with ten soils for 24h. The soil extract solutions were analyzed for...
