Excavating roots with explosives

Creator:: Newton, Michael, 1932-, Zedaker, Shepard M., and Oregon State University. Forest Research Laboratory
Abstract:: "An important limitation In the study of tree roots has traditionally been the time necessary to excavate roots without injuring their fine structure. Thus, many root studies have been based on small samples and consequently contain large errors of estimation. This Note describes how large numbers of root systems from...

Evaluation of 35mm vertical aerial photography for estimating tree mortality

Creator:: Williams, Ralph E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Evaluation of four 35 mm film:lens combinations for estimating conifer mortality showed that large-scale true color images obtained with Kodak High Speed Ektachrome and color infrared images obtained with Kodak Ektachrome Infrared, both exposed through a 135 mm lens were best. Higher correlation coefficients were found for the true color:135...

Can we control brush by helicopter spraying before timber harvest?

Creator:: Newton, Michael, 1932-, White, Diane E., Howard, Kerry Megan, Cline, G., and Oregon State University. Forest Research Laboratory
Abstract:: Aerial application of fosamine ammonium or glyphosate at moderate rates was not adequate for controlling understory brush before final harvesting of mature Douglas-fir (Pseudotsuga menziesii) stands or for reducing vigor of post-harvest sprouting. Symptoms of herbicide injury were those associated with low application rates, suggesting that the canopy intercepted too...

The Cochran airplane seeding experiment : preliminary report

Creator:: Woods, John B. (John Burton), 1890- and Hann, John H.
Abstract:: "One of the basic problems of forest management is that of restoring to productivity denuded areas which cannot be expected to restock through natural means. The most efficient method of regenerating such lands is that method which provides adequate restocking in the shortest time with the least expense. Successful direct...

Remote sensing of forest aboveground biomass using the Geoscience Laser Altimeter System

Creator:: Pflugmacher, Dirk
Abstract:: Accurate estimates of forest aboveground biomass are needed to reduce uncertainties in the terrestrial carbon flux. The Geoscience Laser Altimeter System (GLAS) onboard the Ice, Cloud and land Elevation Satellite is now the first spaceborne lidar sensor that will provide global estimates of vegetation height. This study investigated the utility...

Color infrared aerial photography for root disease detection in the Northern Region

Creator:: Williams, R. E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: "Holes" with dead, dying, and downed trees in the forest canopy could be reliably identified on 9- by 9-inch Kodak Ektachrome Infrared Aero film 2443 as root disease centers. Film scales larger than 1:4000 were best for detection of these "holes." Most commonly occurring causal organisms in root diseased trees...

Protecting Douglas-fir cones and foliage with a systemic insecticide

Creator:: Stipe, Lawrence E., Dewey, Jerald E., and United States. Forest Service. Northern Region
Abstract:: Trees in a Douglas-fir stand infested with western spruce budworm were treated with a systemic insecticide to protect cone and seed production at three locations in Montana during 1983. Treatments applied were (1) acephate as an Acecap implant, (2) acephate as an Inject-A-Cide injection, and (3) control. Potential cone-bearing trees...
