Fiber length in young hybrid Populus stems grown at extremely different rates

Creator:: DeBell, Jeffrey D., Gartner, Barbara L., and DeBell, Dean S.
Abstract:: Length of libriform fibers was measured in rings 2 7 at breast height in 7-year-old hybrid poplar stems from two clones (11-11, a Populus trichocarpa Torr. & Gray ´ P. deltoides Bartr. ex Marsh. hybrid; and D-01, of unknown taxonomic identity) grown in a controlled test of three spacings (0.5,...

Estimating forest productivity in the eastern Siskiyou Mountains of southwestern Oregon using a satellite driven process model, 3-PGS

Creator:: Coops, N. C. and Waring, R. H.
Abstract:: The 3-PGS (physiological principles for predicting growth using satellite data) model generates monthly estimates of transpiration, photosynthesis, and net primary production (NPP), the latter derived as a fixed proportion (0.47) of gross photosynthesis. To assess the reliability of a simplified process model (3-PGS) to predict the productive capacity of coniferous...

High frequency transformation of cottonwoods (genus Populus) by Agrobacterium rhizogene

Creator:: Han, Kyung-Hwan, Gordon, Milton P., and Strauss, Steven H.
Abstract:: Many species of Populus, particularly cottonwoods of sections Aigeiros and Tacamahaca, remain recalcitrant to genetic transformation. We demonstrate that transgenic trees can be readily produced in several poplar genotypes using wild-type Agrobacterium rhizogenes. Hairy roots were produced in a variety of clones that included Populus trichocarpa Torr. & A. Gray,...

Innovativeness in the global forest products industry: Exploring new insights

Creator:: Hansen, Eric, Juslin, Heikki, and Knowles, Christopher David
Abstract:: Innovativeness is a concept that has seen extensive study, yet there remain significant gaps in our understanding of the phenomenon. This is especially true when considering views of practitioners as well as specific industry sectors, such as the forest products industry. The qualitative work described here explores the concept of...

Effect of growth rate on the anatomy, specific gravity, and bending properties of wood from 7-year-old red alder (Alnus rubra)

Creator:: Lei, Hua, Gartner, Barbara L., and Milota, Michael R.
Abstract:: Understanding the association between growth rate and wood properties is of practical importance to maximizing and sustaining wood and fiber production. Anatomical characteristics, specific gravity, and bending properties were determined at breast height for thirty 7-year-old trees with varying growth rates, from a red alder (Alnus rubra Bong.) plantation. Wood...

Intensifying a heuristic forest harvest scheduling search procedure with 2-opt decision choices

Creator:: Bettinger, Pete, 1962-, Boston, Kevin, and Sessions, John
Abstract:: Forest management problems with even-flow and adjacency considerations are difficult to solve optimally. A heuristic search intensification process, which uses two types of decision procedures, changes to single-decision choices (1-opt moves) and changes to two-decision choices simultaneously (2-opt moves), was used in an attempt to locate feasible and efficient solutions...

Influence of precommercial thinning on understory vegetation of young-growth Sitka spruce forests in southeastern Alaska

Creator:: Cole, Elizabeth C., Hanley, Thomas A., and Newton, Michael
Abstract:: The effects of precommercial thinning on the understory vegetative cover of 16- to 18-year-old spruce–hemlock (Picea sitchensis (Bong.) Carrière – Tsuga heterophylla (Raf.) Sarg.) stands were studied in seven replicate areas over seven growing seasons postthinning. Vegetative cover was analyzed at the class level, but species-specific effects were examined in...

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....

Developing a production possibility set of wildlife species persistence and timber harvest value

Creator:: Calkin, David E., Montgomery, Claire A., Schumaker, Nathan H., Polasky, Stephen, Arthur, Jeffrey L., and Nalle, Darek J.
Abstract:: An integrated model, combining spatial wildlife population and timber harvest and growth models, was developed to explore tradeoffs between the likelihood of persistence of a wildlife species, the northern flying squirrel (Glaucomys sabrinus), and timber production on a landscape on the west side of the Oregon Cascade Range. A simplified...

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...
