Land-use in the Willamette Valley from 2004-2017

Creator:: Strimbu, Bogdan M., Mueller-Warrant, George, and Trippe, Kristin
Abstract:: The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...

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...

The Public’s Perception of Fire Prevention and Communication in the Tonto National Forest

Creator:: Lindley, David
Abstract:: As the frequency and intensity of wildfires continue to occur in the West, so does the need for measures intended to improve firefighter safety; public safety; and the protection of property, resources, and wildlife. Furthermore, as human activity in the expanding Wildland Urban Interface increases, so does the need for...

Bearing Strength Capacity of Continuous Supported Timber Beams: Unified Approach for Test Methods and Structural Design Codes

Creator:: Leijten, A. J. M., Franke, S., Quenneville, P., and Gupta, R.
Abstract:: Bearing or compressive strength capacity perpendicular to the grain of timber beams is a troublesome issue. Not only do many different load cases occur in practice that are not covered by structural timber design codes but also these codes provide only a basic provision and vary throughout continents. Code design...

Species, diversity, and density affect tree seedling mortality from Armillaria root rot

Creator:: Gerlach, J. P., Reich, P. B., Puettmann, Klaus J., and Baker, T.
Abstract:: Mortality from Armillaria root rot is a major concern of forest management. Field experiments were conducted in Minnesota to evaluate interspecific differential susceptibility and to assess whether density or species composition, specifically the proportion of conifers in a plot, influences seedling mortality from Armillaria spp. Seedlings of 10 tree species...

Potential for Coastal Wetland Blue Carbon Offset Projects in the Point Reyes Area

Creator:: Minnick, Margaret T.
Abstract:: Point Reyes is a 100-square mile peninsula located on the California coast about 30 miles north of San Francisco. The peninsula, surrounding bays, and neighboring coastal mainland are a unique biodiversity hotspot. The area underwent heavy human use, including ranching and logging, during the late 1800s and early 1900s. Conservation...

Forest soil characteristics in a chronosequence of harvested Douglas-fir forests

Creator:: Griffiths, Robert P. and Swanson, Alan K.
Abstract:: This study was designed to measure the microbiological and chemical characteristics of forest soils in a chronosequence of harvested Douglas-fir (Pseusotsuga menziesii (Mirb.) Franco) stands in different climatic settings. Mineral soil samples were collected along transects running from old-growth (OG) forests into harvested stands of ages 5, 15, and 40...

Twenty years of research on fungus-microbe-plant interactions on Lyman Glacier forefront – lessons learned and questions yet unanswered

Creator:: Jumpponen, Ari, Brown, Shawn P., Trappe, James M., Cazares, Efren, and Strommer, Rauni
Abstract:: Retreating glaciers and the periglacial areas they vacate for organismal colonization produce a harsh environment of extreme radiation, nutrient limitations, and temperature oscillations. They provide a model system for studying mechanisms that drive establishment and early assembly of communities. Here, we synthesize more than twenty years of research at the...
