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...

Long-term effects of forest harvesting on summer low flow deficiets in the Coast Range of Oregon

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...

Aspect Ratio Requirements for Nanotube-Reinforced, Polymer-Matrix Composites

Creator:: Nairn, J. A.
Abstract:: A fiber’s efficiency in a short-fiber composite can be accurately solved by shear-lag methods, which can account for fiber geometry, an imperfect interface (or interphase), and extend to low volume fractions. Such an analysis was used to evaluate the aspect ratio requirements for single-walled nanotubes (SWNT) in a polymeric composite...

The growing season carbon balance of a sub-boreal clearcut 5 years after harvesting using two independent approaches to measure ecosystem CO₂ flux

Creator:: Pypker, Thomas G. and Fredeen, Arthur L.
Abstract:: From 27 June to 3 September 1999, CO2 fluxes from a 5-year-old, 84.15-ha vegetated clearcut in sub-boreal British Columbia were measured using a Bowen ratio energy balance (BREB) system and a second approach (the component model) that was based on scaled up CO2-flux measurements from belowground and plants (spruce seedlings...

Occurrence of preservative-treated wood in a wood recovery center in Western Oregon

Creator:: Morrell, Jeffrey J.
Abstract:: The amounts of treated wood present at a wood recycling center in western Oregon were surveyed over a 10-year period. Treated wood was found at 106 of 112 inspections, but the levels never exceeded 2 percent of the volume present. The amount of treated wood averaged 0.15 percent of the...

A numerical study of the transverse modulus of wood as a function of grain orientation and properties

Creator:: Nairn, John A.
Abstract:: Finite element analysis was used to study the effective transverse modulus of solid wood for all possible end-grain patterns. The calculations accounted for cylindrical anisotropy of wood within rectangular specimens and explicitly modeled wood as a composite of earlywood and latewood. The effective modulus was significantly reduced by growth ring...

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...

Assessment of the BLM Exemption Request for Sales Ruled to Jeopardize the Northern Spotted Owl: Including a statement of conclusions by Tom Walsh, Oregon Representative on the Endangered Species Committee

Creator:: Greber, Brian J.
Abstract:: In September 1991, the Bureau of Land Management asked the Secretary of the Interior to convene the Endangered Species Committee. The Bureau wanted permission to proceed with 44 timber sales In Oregon that the U.S. Fish and Wildlife Service had ruled would jeopardize the continued existence of the northern spotted...
