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...

Leaf-level physiology in four subalpine plants in tephra-impacted forests during drought

Creator:: Watt, Abby J., Fischer, Dylan G., Antos, Joseph A., and Zobel, Donald B.
Abstract:: Ecological impacts of climate change in the Pacific Northwest may hinge on acclimation to drier summers, highlighting the importance of plant physiological studies in forests. Evaluating dominant forest plant species under old-growth and managed forest conditions is similarly important as timber harvest might change microclimates and alter drought effects on...

Stumps fumigated with chloropicrin: effects on surrounding plants

Creator:: Luoma, Daniel L. and Thies, Walter G.
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stumps, both healthy and infected by Phellinus weirii (Murr.)Gilbertson, were fumigated with chloropicrin at a clearcut site on Washington s Olympic Peninsula. Vegetation cover on plots adjacent to treated and untreated stumps was evaluated to determine fumigant effects on vascular plants and moss. Ninety-eight vascular...

The growing season carbon balance of a sub-boreal clearcut 5 years after harvesting using two independent approaches to measure ecosystem CO₂ flux

Creator:: Pypker, Thomas G. and Fredeen, Arthur L.
Abstract:: From 27 June to 3 September 1999, CO2 fluxes from a 5-year-old, 84.15-ha vegetated clearcut in sub-boreal British Columbia were measured using a Bowen ratio energy balance (BREB) system and a second approach (the component model) that was based on scaled up CO2-flux measurements from belowground and plants (spruce seedlings...

Development of Douglas-fir seedling root architecture in response to localized nutrient supply

Creator:: Jacobs, Douglass Frederick, Rose, Robin, and Haase, Diane L.
Abstract:: Three months following sowing, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were transplanted into pots with controlled-release fertilizer (CRF) applied at rates of 0, 8, 16, and 24 g/2200 cm3 soil as a single uniform layer beneath the root system. Seedlings were destructively harvested periodically, and roots were divided into vertical...

Effects of live crown on vertical patterns of wood density and growth in Douglas-fir

Creator:: Gartner, Barbara L., North, Eric M., Johnson, G. R., and Singleton, Ryan
Abstract:: It would be valuable economically to know what are the biological triggers for formation of mature wood (currently of high value) and (or) what maintains production of juvenile wood (currently of low value), to develop silvicultural regimes that control the relative production of the two types of wood. Foresters commonly...

A chronosequence of wood decomposition in the boreal forests of Russia

Creator:: Yatskov, Mikhail, Harmon, Mark E., and Krankina, Olga N.
Abstract:: Coarse woody debris (CWD), represented by logs and snags >10 cm in diameter and >1 m in length, was sampled at eight sites in Russian boreal forests to determine the specific density of decay classes and decomposition rates. Tree species sampled included Abies siberica Ledeb., Betula pendula Roth., Betula costata...

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....

Geostatistical modeling of riparian forest microclimate and its implications for sampling

Creator:: Eskelson, Bianca N.I., Anderson, Paul D., Hagar, Joan C., and Temesgen, Hailemariam
Abstract:: Les modèles de prédiction du microclimat pour différentes conditions de station dans les zones riveraines boisées des cours d’eau de tête de bassin sont peu développés et les procédures d’échantillonnage pour caractériser les gradients sous-jacents du microclimat riverain sont rares. Nous avons utilisé des données de microclimat riverain collectées le...

Effects of silvicultural practices on carbon stores in Douglas-fir – western hemlock forests in the Pacific Northwest, U.S.A.: results from a simulation model

Creator:: Harmon, Mark E. and Marks, Barbara
Abstract:: We used a new model, STANDCARB, to examine effects of various treatments on carbon (C) pools in the Pacific Northwest forest sector. Simulation experiments, with five replicates of each treatment, were used to investigate the effects of initial conditions, tree establishment rates, rotation length, tree utilization level, and slash burning...
