Regenerating white spruce, paper birch, and willow in south-central Alaska

Creator:: Cole, E. C., Newton, Michael, and Youngblood, A.
Abstract:: The current spruce bark beetle (Dendroctonus rufipennis Kirby) epidemic in interior Alaska is leaving large expanses of dead spruce with little spruce regeneration. Many of these areas are habitat for moose (Alces alces). To establish spruce regeneration and improve browse production for moose, paper birch (Betula papyrifera Marsh), willow (Salix...

Structure and composition of unmanaged riparian forests in the coastal mountains of Oregon, U.S.A.

Creator:: Pabst, Robert J. and Spies, Thomas A.
Abstract:: We characterized the structure and composition of unmanaged riparian forests in three river basins in Oregon’s coastal mountains. Our objective was to evaluate stand attributes at three spatial scales: streamside (site), drainage network (stream order), and basin (subregion). Data on basal area, species composition, snag density, canopy cover, and tree...

The effect of local stand structure on growth and growth efficiency in heterogeneous stands of ponderosa pine and lodgepole pine in central Oregon

Creator:: Mainwaring, Douglas B. and Maguire, Douglas A. (Douglas Alan)
Abstract:: Basal area and height growth were analyzed for individual trees in uneven-aged ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and lodgepole pine (Pinus contorta Dougl. ex. Loud.) stands in central Oregon. Basal area growth was modeled as a function of other stand and tree variables to address three general objectives:...

Effects of overtopping on growth of white spruce in Alaska

Creator:: Cole, E. C., Newton, M., and Youngblood, A.
Abstract:: Early establishment of competing vegetation often presents an obstacle to the success of planted white spruce (Picea glauca (Moench) Voss) seedlings. We followed growth and development of white spruce and associated vegetation for up to 17 years in Alaska's boreal forests to quantify roles of overtopping plant cover in suppressing...

Tree-ring analysis of the fungal disease Swiss needle cast in western Oregon coastal forests

Creator:: Lee, E. Henry, Beedlow, Peter A., Waschmann, Ronald S., Burdick, Connie A., and Shaw, David C.
Abstract:: Swiss needle cast (SNC), an important fungal disease of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), has increased in severity throughout its natural and introduced range over the last half century. The role of climate change and forest management practices in the increase is unclear. We analyzed tree-ring chronologies from six late-successional...

Density, ages, and growth rates in old-growth and young-growth forests in coastal Oregon

Creator:: Tappeiner, John C., Huffman, David W. (William), 1962-, Marshall, David, Spies, Thomas A., and Bailey, John D.
Abstract:: We studied the ages and diameter growth rates of trees in former Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) old-growth stands on 10 sites and compared them with young-growth stands (50-70 years old, regenerated after timber harvest) in the Coast Range of western Oregon. The diameters and diameter growth rates for the...

Effect of thinning and prescribed fire restoration treatments on woody debris and snag dynamics in a Sierran old-growth, mixed-conifer forest

Creator:: Innes, James C., North, Malcolm P., and Williamson, Nathan
Abstract:: Forest managers have little information of the effects of common restoration treatments, thinning and burning, on dead woody material (DWM) dynamics in fire-suppressed forests. Fine woody debris (FWD; 0.6–29.9 cm), coarse woody debris (CWD; ≥30.0 cm), and snags (≥5 cm) were inventoried and mapped in eighteen 4 ha plots before...

The CP4 transgene provides high levels of tolerance to Roundup® herbicide in field-grown hybrid poplars

Creator:: Meilan, R., Han, K.-H., Ma, C., DiFazio, Stephen P., Eaton, J. A., Hoien, E. A., Stanton, B. J., Crockett, R. P., Taylor, M. L., James, R. R., Skinner, J. S., Jouanin, L., Pilate, G., and Strauss, S. H.
Abstract:: We tested two genes together in hybrid poplars (genus Populus), CP4 and GOX, for imparting tolerance to glyphosate (the active ingredient in Roundup® herbicide). Using Agrobacterium-based transformation, 80 independent transgenic lines (i.e., products of asexual gene transfer) were produced in a variety of hybrid poplar clones (40 lines in Populus...

Ten-year growth and mortality in young Douglas-fir stands experiencing a range in Swiss needle cast severity

Creator:: Maguire, Douglas A., Mainwaring, Douglas B., and Kanaskie, Alan
Abstract:: Swiss needle cast, a foliar disease caused by the Ascomycete Phaeocryptopus gaeumannii (T. Rohde) Petr., continues to afflict Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in north coastal Oregon. Permanent plots were installed in 1998 to assess growth impacts and monitor disease severity. Gross periodic annual increment was measured for three 2-year...

Determination of relative economic weights for multitrait selection in coastal Douglas-fir

Creator:: Aubry, Carol A., Adams, W. T., and Fahey, Thomas D.
Abstract:: Abstract: Relationships between tree traits and tree value for lumber production were investigated. For the purposes of estimating relative economic weights for use in multitrait selection in coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii), tree height, diameter at breast height, and branch diameter were measured on 164 trees (ages...
