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...

Mapping and imputing potential productivity of Pacific Northwest forests using climate variables

Creator:: Latta, Gregory, Temesgen, Hailemariam, and Barrett, Tara M.
Abstract:: Regional estimation of potential forest productivity is important to diverse applications, including biofuels supply, carbon sequestration, and projections of forest growth. Using PRISM (Parameter-elevation Regressions on Independent Slopes Model) climate and productivity data measured on a grid of 3356 Forest Inventory and Analysis plots in Oregon and Washington, we evaluated...

Estimating Cavity Tree Abundance Using Nearest Neighbor Imputation Methods for Western Oregon and Washington Forests

Creator:: Temesgen, Hailemariam, Barrett, Tara M., and Latta, Greg
Abstract:: Cavity trees contribute to diverse forest structure and wildlife habitat. For a given stand, the size and density of cavity trees indicate its diversity, complexity, and suitability for wildlife habitat. Size and density of cavity trees vary with stand age, density, and structure. Using Forest Inventory and Analysis (FIA) data...

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)...

Host–parasite distributions under changing climate: Tsuga heterophylla and Arceuthobium tsugense in Alaska

Creator:: Barrett, Tara M., Latta, Greg, Hennon, Paul E., Eskelson, Bianca N.I., and Temesgen, Hailemariam
Abstract:: Dwarf mistletoes (Arceuthobium species) influence many processes within forested ecosystems, but few studies have examined their distribution in relation to climate. An analysis of 1549 forested plots within a 14.5 million ha region of southeast Alaska provided strong indications that climate currently limits hemlock dwarf mistletoe (Arceuthobium tsugense (Rosendahl) G.N....

Carbon balance on federal forest lands of Western Oregon and Washington: The impact of the Northwest Forest Plan

Creator:: Krankina, Olga N., Harmon, Mark E., Schnekenburger, Frank, and Sierra, Carlos A.
Abstract:: The management of federal forest lands in the Pacific Northwest (PNW) region changed in early 1990s when the Northwest Forest Plan (NWFP) was adopted with the primary goal to protect old-growth forest and associated species. A major decline in timber harvest followed, extending an earlier downward trend. The historic and...

Forest Measurement and Biometrics in Forest Management: Status and Future Needs of the Pacific Northwest USA

Creator:: Temesgen, Hailemariam, Goerndt, Michael E., Johnson, Greg P., Adams, Darius M., and Monserud, Robert A.
Abstract:: Forest measurement and biometrics (FMB) programs have been at the heart of forestry education in North America since its beginnings at the Biltmore Forest School more than 100 years ago. Over the intervening period, the field of forestry has changed in critical ways. There are many forest management and policy...

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...

Decomposition of Basamid in Douglas-fir heartwood: Laboratory studies of a potential wood fumigant

Creator:: Forsyth, Paul G. and Morrell, Jeffrey J.
Abstract:: Basamid (3,5-dimethyl-l,3,5,2H-tetrahydrothiadiazine-2-thione), a crystalline powder first used as a soil sterilant, has shown promise as a wood fumigant. This chemical decomposes to methylisothiocyanate (MITC), the primary active ingredient, as well as other products; but the rate of decomposition in wood is too slow to be effective unless certain catalysts are...

Imputing Mean Annual Change to Estimate Current Forest Attributes

Creator:: Eskelson, Bianca N.I., Barrett, Tara M., and Temesgen, Hailemariam
Abstract:: When a temporal trend in forest conditions is present, standard estimates from paneled forest inventories can be biased. Thus methods that use more recent remote sensing data to improve estimates are desired. Paneled inventory data from national forests in Oregon and Washington, U.S.A., were used to explore three nearest neighbor...
