Potential financial returns from alternative silvicultural prescriptions in second-growth stands of coastal British Columbia

Creator:: Howard, Andrew F. and Temesgen, H.
Abstract:: This paper reports the findings from a study made of the potential financial returns from nine alternative silvicultural prescriptions applied to four case-study stands of second growth in coastal British Columbia. The objectives were to compare prescriptions based on partial cutting with conventional clear-cutting and to explore the effects of...

Long-term patterns of diameter and basal area growth of old-growth Douglas-fir trees in western Oregon

Creator:: Poage, Nathan Jeremy and Tappeiner, John C., II
Abstract:: Diameter growth and age data collected from stumps of 505 recently cut old-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees at 28 sample locations in western Oregon (U.S.A.) indicated that rapid early and sustained growth of old Douglas-fir trees were extremely important in terms of attaining large diameters at ages 100–300...

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...

Salmonberry and salal annual aerial stem production: the maintenance of shrub cover in forest stands

Creator:: Tappeiner, John C., Zasada, John C., Huffman, David W. (William), 1962-, and Ganio, Lisa M.
Abstract:: Annual sprouting of aerial stems and ramets enables populations of salmonberry (Rubus spectabilis Pursh), salal (Gaultheria shallon Pursh), and probably other forest shrubs to maintain dense covers (>20 000 stems/ha). We studied annual stem production of salmonberry on cut (all stems cut within 15 cm of the ground) and uncut...

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...

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...

Spatial and temporal quantification of forest residue volumes and delivered costs

Creator:: Wells, Lucas A., Chung, Woodam, Anderson, Nathaniel M., and Hogland, John S.
Abstract:: Growing demand for bioenergy, biofuels, and bioproducts has increased interests in the utilization of biomass residues from forest treatments as feedstock. In areas with limited history of industrial biomass utilization, uncertainties in the quantity, distribution, and cost of biomass production and logistics can hinder the development of new bio-based industries....

Influence of forest age on forms of carbon in Douglas-fir soils in the Oregon Coast Range

Creator:: Entry, James A. and Emmingham, William H.
Abstract:: The amount and type of carbon (C) in a forest soil reflects the past balance between C accumulation and loss. In an old-growth forest soil, C is thought to be in dynamic equilibrium between accumulations and losses. Disturbance upsets this equilibrium by altering the microclimate, the amount and type of...

Harvesting impacts on soil and understory vegetation: the influence of season of harvest and within-site disturbance patterns on clear-cut aspen stands in Minnesota

Creator:: Berger, Alaina L., Puettmann, Klaus J., and Host, George E.
Abstract:: We investigated impacts of harvesting on soil disturbance and vegetation in the aspen cover type of northern Minnesota, United States. The soil disturbance (resistance to penetration) and understory vegetation were characterized for 19 sites on five 60-m2 plots placed along a disturbance gradient: landings (high harvesting traffic), skid trails (intermediate...

Short-term effects of fire and forest thinning on truffle abundance and consumption by Neotamias speciosus in the Sierra Nevada

Creator:: Meyer, Marc D., North, Malcolm P., and Kelt, Douglas A.
Abstract:: In many western North American forests, prescribed burning and mechanical thinning are widely used to reduce fuels and restore stand conditions after a century of fire suppression. Few studies have followed the relative impacts of these treatments on the production and consumption of truffles in forest ecosystems, particularly in the...
