Detecting landscape changes in the interior of British Columbia from 1975 to 1992 using satellite imagery

Creator:: Sachs, Donald L., Sollins, Phillip, and Cohen, Warren B.
Abstract:: To consider the regional scale effects of forest management requires complete and consistent data over large areas. We used Landsat Thematic Mapper and Multispectral Scanner (TM and MSS) imagery to map forest cover and detect major disturbances between 1975 and 1992 for a 4.2 x 106 ha area of interior...

Rootstock effects on scion growth and reproduction in 8-year-old grafted loblolly pine

Creator:: Jayawickrama, K. J. S., McKeand, S. E., and Jett, J. B.
Abstract:: Contributions of sites, rootstocks, and scion clones (and the nteractions between these factors) to scion growth and reproduction were studied in loblolly pine (Pinus taeda L.). Twenty-five full-sib families were used as rootstocks. Six scion clones were grafted on them in all combinations. Study sites were three seed orchards in...

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...

Methods for evaluating crown area profiles of forest stands

Creator:: Dubrasich, Michael E., Hann, David W., and Tappeiner, John C., II
Abstract:: Canopy architectures of five structurally complex forest stands and three structurally simple forest stands in southwest Oregon and the Willamette Valley, Oregon, were evaluated and quantified through crown area profiles. Mixed conifer and mixed conifer-hardwood stands across a range of sites were sampled for crown widths and heights. Crown width...

Incorporation of nitrogen from decomposing red alder leaves into plants and soil of a recent clearcut in Oregon

Creator:: Swanston, Christopher W. and Myrold, David Douglas
Abstract:: Nitrogen incorporation from red alder (Alnus rubra Bong.) into an Oregon upland mesic forest soil was studied by tracing the fate of 15N added as 15N-labeled alder leaf litter. The recovery of 15N in vegetation, litter, light- and heavy-fractions of the soil, the chloroform-labile (microbial biomass) pool, and the whole...

Conifer response to three silvicultural treatments in the Oregon Coast Range foothills

Creator:: Walter, Scott T. and Maguire, Chris C.
Abstract:: This study assessed growth, condition, and mortality of residual trees one decade after harvest across three silvicultural treatments in thirty 85- to 125-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the Oregon Coast Range foothills. Group-selection cuts had 33% of the entire stand volume extracted as patches approximately 0.2–0.8 ha...

Modeling the incidence and severity of hemlock dwarf mistletoe in 110-year-old wind-disturbed forests in Southeast Alaska

Creator:: Trummer, L. M., Hennon, P. E., Hansen, E. M., and Muir, P. S.
Abstract:: A model was developed to predict the severity of dwarf mistletoe (Arceuthobium tsugense (Rosendahl) G.N. Jones) in western hemlock trees (Tsuga heterophylla (Raf.) Sarg.) that developed within forests of Southeast Alaska that experienced near-catastrophic windthrow in the late 1800s. The model suggests that the degree of dwarf mistletoe severity on...

Growth and wood properties of genetically improved loblolly pine: propagation type comparison and genetic parameters

Creator:: Antony, Finto, Schimleck, Laurence R., Jordan, Lewis, Hornsby, Benjamin, Dahlen, Joseph, Daniels, Richard F., Clark, Alexander, III, Apiolaza, Luis A., and Huber, Dudley
Abstract:: The use of clonal varieties in forestry offers great potential to improve growth traits (quantity) and wood properties (quality) of loblolly pine (Pinus taeda L.). Loblolly pine trees established via somatic embryogenesis (clones), full-sib zygotic crosses, and half-sib zygotic open-pollinated families were sampled to identify variation in growth and wood...

Canopy type, forest floor, predation, and competition influence conifer seedling emergence and early survival in two Minnesota conifer-deciduous forests

Creator:: Cornett, Meredith W., Puettmann, Klaus J., and Reich, Peter B.
Abstract:: There is concern that the conifer component of mixed conifer-deciduous forests in the Great Lakes region is on the decline, possibly the result of insufficient conifer regeneration. Limitations on conifer regeneration that occur during the first 18 months of seedling emergence and establishment were examined for Abies balsamea (L.) Mill....

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....
