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...

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...

Creator:: Segura, Catalina, Bladon, Kevin, Hatten, Jeff, Jones, Julia A., Hale, Cody, Ice, George, and Souder, Jon
Abstract:: We examined long-term changes in daily streamflow associated with forestry practices with two datasets (this one and the original Alsea Streamflow dataset (1972) over a 60-year period (1959–2017) in the Alsea Watershed Study, Oregon Coast Range, Pacific Northwest, USA. In this contemporary period, 2006 to 2017 (12 water years), data...

Effect of floods of different magnitude on the macroinvertebrate communities of Matarranya stream (Ebro river basin, NE Spain)

Creator:: Argerich, A., Puig, M. A., and Pupilli, E.
Abstract:: In October 2000, the Matarranya River suffered an extraordinary flood with a measured flow rate of approximately 450 m³/s in the town of Vall-de-roures and a return period of about 500 years, according to the Ebro Hydrographic Confederation. The objective of this study was to determine the influence of the...

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...

A catchment-scale assessment of stream temperature response to contemporary forest harvesting in the Oregon Coast Range

Creator:: Kevin Bladon, Nicholas Cook, Jeffery Light, and Catalina Segura
Abstract:: Historical forest harvesting practices were reviewed in the original Alsea Watershed Study where they found increased energy loading to the stream and produced higher stream temperatures. This was an important early research site that led to the development of contemporary forest management practices to protect water quality and fish habitat...

Durability of a changing western redcedar resource

Creator:: Freitag, Camille M. and Morrell, Jeffrey J.
Abstract:: The heartwood of western redcedar (Thuja plicuta) is known for its natural resistance to fungal attack, but some users of western redcedar utility poles have suggested that its durability may be diminished as suppliers begin to harvest trees from younger stands. The decay resistance of western redcedar samples from the...

Pacific marten occupancy and detection probability in relation to infrastructure and environmental factors in the southern Cascade Mountains

Creator:: Hill, Deborah J.
Abstract:: Humans benefit from being in nature and recreating, however outdoor recreation can negatively impact wildlife, including species of conservation concern such as the Pacific marten (Martes caurina), which has been used as a focal species for demonstrating ecosystem integrity. Marten population densities decline following intensive forest management activities, but impacts...

The effects of factor supply assumptions on intertemporal timber supply behavior: the cases of investable funds and land

Creator:: Adams, Darius M., Alig, Ralph J., McCarl, Bruce A., Winnett, Steven M., and Callaway, J.M.
Abstract:: Intertemporal timber supply models typically assume perfect capital markets and perfectly inelastic supplies of land. Using a dynamic model of U.S. timber and agriculture markets, we examine (i) borrowing limits or capital constraints, in which investment in forest management on nonindustrial private ownerships is restricted, and (ii) a nonzero elasticity...

Evidence for xylem embolism as a primary factor in dehydration-induced declines in leaf hydraulic conductance

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Hydraulic conductance of leaves (K[subscript leaf]) typically decreases with increasing water stress and recent studies have proposed different mechanisms responsible for decreasing K[subscript leaf]. We measured K[subscript leaf] concurrently with ultrasonic acoustic emissions (UAEs) in dehydrating leaves of several species to determine whether declining K[subscript leaf] was associated with xylem...

Predicting branch diameters on second-growth Douglas-fir from tree-level descriptors

Creator:: Maguire, Douglas A., Johnston, Stuart R., and Cahill, James M.
Abstract:: The quality of lumber and veneer recovered from logs of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is directly influenced by the maximum limb size attained on the crop tree. Because limb sizes are influenced by standdensity regimes, a need has arisen for quantitative tools that link a wide array of silvicultural...

Mechanical stability of ultrathin Ge/Si film on SiO2: The effect of Si/SiO2 interface

Creator:: Huang, Minghuang, Nairn, John A., Liu, Feng, and Lagally, M. G.
Abstract:: We perform two-dimensional linear elastic finite element analysis to investigate the mechanical stability of ultrathin Ge/Si film grown on or bonded to SiO₂, using imperfect interface elements between Si and SiO₂ to model Si/SiO₂ interfacial slippage. We demonstrate that the overall composite film is stable when only the tangential slippage...

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...

Time dependence of triplet-singlet excitation transfer from compact poly rA to bound dye at 77 K

Creator:: Pearlstein, R. M., Van Nostrand, F., and Nairn, J. A.
Abstract:: The nonexponential phosphorescence decay of a highly folded form of poly-riboadenylic acid (poly rA) with noncovalently bound dye is explained by a novel application of a well-known theory of electronic excitation transfer based on the Förster mechanism. This theory, originally used to describe singlet-singlet energy transfer from donor molecules to...

Hydraulic safety margins and embolism reversal in stems and leaves: Why are conifers and angiosperms so different?

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Angiosperm and coniferous tree species utilize a continuum of hydraulic strategies. Hydraulic safety margins (defined as differences between naturally occurring xylem pressures and pressures that would cause hydraulic dysfunction, or differences between pressures resulting in loss of hydraulic function in adjacent organs (e.g., stems vs. leaves) tend to be much...
