Voluntary Environmental Programs at an Alpine Ski Area: Visitor Perceptions, Attachment, Value Orientations, and Specialization

Creator:: Needham, Mark D. and Little, Christopher M.
Abstract:: This article examines visitor perceptions of voluntary environmental programs (VEPs) at the Mt. Bachelor ski area in Oregon, USA by examining what they know about VEPs, how these programs influence motivations to visit this area currently and in the future, and how place attachment, value orientations, and specialization influence these...

Arbutus menziesii (Ericaceae) facilitates regeneration dynamics in mixed evergreen forests by promoting mycorrhizal fungal diversity and host connectivity

Creator:: Kennedy, Peter G., Smith, Dylan P., Horton, Tom R., and Molina, Randy J.
Abstract:: • Premise of study: In the mixed evergreen forests in the western United States, Arbutus menziesii is able to quickly resprout following disturbance and, as such, act as a nurse tree during forest regeneration. The mechanism for this nurse tree effect has frequently been ascribed to mycorrhizal fungi, but no...

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...

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....

Model-Assisted Forest Yield Estimation with Light Detection and Ranging

Creator:: Strunk, Jacob L., Reutebuch, Stephen E., Andersen, Hans-Erik, Gould, Peter J., and McGaughey, Robert J.
Abstract:: Previous studies have demonstrated that light detection and ranging (LiDAR)-derived variables can be used to model forest yield variables, such as biomass, volume, and number of stems. However, the next step is underrepresented in the literature: estimation of forest yield with appropriate confidence intervals. It is of great importance that...

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...

Soil carbon and nitrogen pools and processes in an old-growth conifer forest 13 years after trenching

Creator:: Hart, Stephen C. and Sollins, Phil
Abstract:: We measured surface soil (0–15 cm) C and N pools and processes inside and outside an area that had been trenched 13 years earlier in an old-growth conifer forest (>450 years) to assess the long-term impacts of reduced root inputs on C and N turnover. Trenching, combined with frequent clipping...

A model-data comparison of gross primary productivity: Results from the North American Carbon Program site synthesis

Altaf, Barr, Alan, Chen, Jing M., Davis, Kenneth J., Dimitrov, Dimitre, Hilton, Timothy W., Hollinger, David Y., Humphreys, Elyn, Poulter, Benjamin, Raczka, Brett M., Richardson, Andrew D., Sahoo, Alok, Thornton, Peter, Vargas, Rodrigo, Verbeeck, Hans, Anderson, Ryan, Baker, Ian, Black, T.

William, Oechel, Walter, Peng, Changhui, Price, David T., Ricciuto, Dan, Riley, William J., Roulet, Nigel, Tian, Hanqin, Tonitto, Christina, Torn, Margaret, Weng, Ensheng, and Zhou, Xiaolu
Abstract:: Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...

Thinning of young Douglas-fir forests decreases density of northern flying squirrels in the Oregon Cascades

Creator:: Manning, Tom, Hagar, Joan C., and McComb, Brenda C.
Abstract:: Large-scale commercial thinning of young forests in the Pacific Northwest is currently promoted on public lands to accelerate the development of late-seral forest structure for the benefit of wildlife species such as northern spotted owls (Strix occidentalis caurina) and their prey, including the northern flying squirrel (Glaucomys sabrinus). Attempts to...
