Interactions of ammoniacal copper zinc arsenate (ACZA) with Douglas-fir

Creator:: Lebow, Stan T. and Morrell, Jeffrey J.
Abstract:: Tests were conducted to determine the effect of ACZA composition on fixation and the roles of adsorption and precipitation in fixation. The sites of copper and zinc adsorption within the treated wood and the bonding environment of adsorbed copper were also examined. The results generally support the finding that arsenic...

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...

The effect of pH on decomposition of Mylone (dazomet) and tridipam to fungitoxic methylisothiocyanate in wood

Creator:: Morrell, Jeffrey J., Sexton, Camille M., and Lebow, Stan
Abstract:: Mylone@ and tridipam are two solid chemicals that decompose to produce methylisothiocyanate (MIT), a highly effective wood fumigant. In this study, two techniques -- a rapid, test-tube method and small-scale, wood-block assay -- were used to determine the effect of the pH of various chemical buffers on the decomposition of...

Predictive mapping of forest composition and structure with direct gradient analysis and nearest-neighbor imputation in coastal Oregon, U.S.A.

Creator:: Ohmann, Janet L. and Gregory, Matthew J.
Abstract:: Spatially explicit information on the species composition and structure of forest vegetation is needed at broad spatial scales for natural resource policy analysis and ecological research. We present a method for predictive vegetation mapping that applies direct gradient analysis and nearest-neighbor imputation to ascribe detailed ground attributes of vegetation to...

An econometric analysis of output supply and input demand in the Canadian softwood lumber industry

Creator:: Latta, Gregory S. and Adams, Darius M.
Abstract:: Few studies have examined the own-price elasticity of Canadian softwood lumber supply or output-adjusted factor demand elasticities over the past two decades, despite the utility of these measures in understanding producer response to tariffs, to market shifts (such as the decline in U.S. public harvest), and to changes in domestic...

Nutrient stores and dynamics of woody detritus in a boreal forest: modeling potential implications at the stand level

Creator:: Krankina, Olga N., Harmon, Mark E., and Griazkin, Anatolii V.
Abstract:: Concentrations of 14 chemical elements (Al, B, C, Ca, Cu, Fe, K, N, Mg, Mn, Na, P, S, Zn) were measured in wood and bark of 126 sample trees representing different stages of decomposition in three major tree species of northwestern Russia: Scots pine (Pinus sylvestris L.), Norway spruce (Picea...

Kalapuya brunnea gen. & sp. nov. and its relationship to the other sequestrate genera in Morchellaceae

Creator:: Trappe, Matthew J., Trappe, James M., and Bonito, Gregory M.
Abstract:: Kalapuya is described as a new, monotypic truffle genus in the Morchellaceae known only from the Pacific northwestern United States. Its relationship to other hypogeous genera within Morchellaceae is explored by phylogenetic analysis of the ribosomal LSU and EF1α protein coding region. The type species, K. brunnea, occurs in Douglas-fir...

Private timber harvest potential in Eastern Oregon

Creator:: Adams, Darius Mainard, 1944-, Latta, Gregory S., and Oregon State University. Forest Research Laboratory
Abstract:: Growing stock inventory on industrial and nonindustrial private forest (NIPF) lands in eastern Oregon has declined over the past 20 yr, as harvesting and mortality losses to insects and disease have outpaced growth. Over the same time period, harvest rates on private lands have varied, with no distinct trend to...

Analysis of potential impacts of climate change on forests of the United States Pacific Northwest

Creator:: Latta, Gregory, Temesgen, Hailemariam, Adams, Darius M., and Barrett, Tara
Abstract:: As global climate changes over the next century, forest productivity is expected to change as well. Using PRISM climate and productivity data measured on a grid of 3356 plots, we developed a simultaneous autoregressive (SAR) model to estimate the impacts of climate change on potential productivity of Pacific Northwest (PNW)...
