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...

Interactions between sodium N-methyldithiocarbamate and Douglas-fir heartwood

Creator:: Miller, D. B. and Morrell, Jeffrey J.
Abstract:: Vapam(r) (NaMDC) is the fumigant most commonly used to arrest and control decay of utility poles. While volatile fungitoxins are detectable only 1 to 2 years after treatment, poles treated with Vapam(r) remain free of decay fungi for 6 to 17 years. Vapam(r) decomposes to produce volatile fungicides as well...

N₂-Fixing Red Alder Indirectly Accelerates Ecosystem Nitrogen Cycling

Creator:: Perakis, Steven S., Matkins, Joselin J., and Hibbs, David E.
Abstract:: Symbiotic N₂-fixing tree species can accelerate ecosystem N dynamics through decomposition feedbacks via both direct and indirect pathways. Direct pathways include the production of readily decomposed leaf litter and increased N supply to decomposers, whereas indirect pathways include increased tissue N and altered detrital dynamics of non-fixing vegetation. To evaluate...

Controlling decay fungi in Douglas-fir heartwood with pelletized sodium n-methyldithiocarbamate

Creator:: Sexton, Camille M., Morrell, Jeffrey J., and Newbill, Mark A.
Abstract:: A small block test was used in assessing whether pelletized sodium n-methyldithiocarbamate (NaMDC) would decompose and produce methylisothiocyanate (MITC) and thereby eliminate Antrodia carbonica colonies from Douglas-fir heartwood. Also evaluated were the effects of wood moisture content, dosage, incubation period, pH level, and presence of copper sulfate on percentage of...

Methylisothiocyanate fumigant content of Douglas-fir heartwood at various moisture levels after treatment with solid sodium N-methyldithiocarbamate

Creator:: Lebow, Stan T. and Morrell, Jeffrey J.
Abstract:: The relationship between moisture content and the presence of methylisothiocyanate (MITC) in wood following various applications of sodium n-methyldithiocarbamate (NaMDC) was investigated with small Douglas-fir heartwood blocks. While MITC levels were initially higher in wetter blocks, MITC levels in drier blocks remained more stable over the 8-week test period. The...

Ionic balance and organic acids in western redcedar, western hemlock, and Douglas-fir seedlings grown in low- and high-N soils

Creator:: Graff, J. E., Hermann, Richard K., and Zaerr, J. B.
Abstract:: Seedlings of western redcedar (Thuja plicata Donn ex. D. Don), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were transplanted into soils with low and high levels of available NO3 – (and total N). Current-year foliage was sampled after 10 weeks to determine the effect of...

Douglas-fir soil C and N properties a decade after termination of urea fertilization

Creator:: Homann, Peter S., Caldwell, Bruce A., Chappell, H. N., Sollins, Phillip, and Swanston, Chris W.
Abstract:: Chemical and microbial soil properties were assessed in paired unfertilized and urea fertilized (>89 g N·m–2) plots in 13 second-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands distributed throughout western Washington and Oregon. A decade following the termination of fertilization, fertilized plots averaged 28% higher total N in the O layer...

Fine-root decomposition and N dynamics in coniferous forests of the Pacific Northwest, U.S.A.

Creator:: Chen, Hua, Harmon, Mark E., Sexton, Jay, and Fasth, Becky
Abstract:: We examined the effects of species, initial substrate quality, and site differences (including temperature, precipitation, and soil N availability) on fine-root (<2 mm diameter) decomposition in litter bags and its N dynamics in Sitka spruce (Picea sitchensis (Bong) Carrière), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), and ponderosa pine (Pinus ponderosa Dougl....

Evaluation of factors affecting natural reproduction of forest trees in central western Oregon

Creator:: Bever, Dale N.
Abstract:: This study was started in 1947 to investigate the value of various types and quantities of seed source in the establishment of reproduction on cutover land, and to determine the apparent effects of various man-made and natural factors upon the rate of restocking. The man-made and natural factors to be...
