Detection of 2,4-D herbicide damage using ground-based measurements : implications for remote sensing

Creator:: McCreight, Richard W.
Abstract:: Spectral patterns of three brush species under the influence of herbicide treatment were investigated to evaluate the effectiveness of monitoring forest vegetation management using ground-based and remote sensing techniques. Foliage of Pacific rhododendron (Rhododendron macrophyllum D. Don), golden chinkapin (Castanopsis chrysophylla Dougl.), and hairy manzanita (Arctostaphylos columbiana Piper) sprayed with...

Competitive effects of overtopping vegetation on Douglas-fir morphology in the Oregon Coast Range

Creator:: Chan, Samuel S.
Abstract:: The response of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) saplings to various levels of brush overtopping when growing on three north-facing sites in the Oregon Coast Range was investigated for two consecutive years. A fisheye (hemispherical) photographic technique combined with a digitizing computer system was used to determine the percentage of...

The effects of mechanical and chemical site preparation on ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and lodgepole pine (Pinus contorta Dougl. ex Loud.) performance, associated vegetation, and soil properties in southcentral Oregon eight years after planting

Creator:: Ross, Darrell W.
Abstract:: The effects of six alternative site preparation treatments were compared at three different sites in southcentral Oregon. Treatments included a logged-only control, ripping, brushblading, disking, chemical, and chemical followed by disking. Subplots containing ponderosa pine bareroot (2+0) and containerized (1+0) and lodgepole pine containerized (1+0) seedlings were also included in...

Carbon flux patterns on U.S. public timberlands under alternative timber harvest policies

Creator:: Shanks, Alyssa V.
Abstract:: This study considers trade-offs between timber harvest and carbon sequestration on National Forest and other public lands by contemporaneously linking a model of public harvest and inventory to a carbon accounting system. The public harvest model treats three harvest scenarios. The first minimizes the cost of meeting harvest requests that...

Overstory composition and stand structure shifts within inter-mixed ponderosa pine and lodgepole pine stands of the south-central Oregon pumice zone

Creator:: Shuffield, Chaylon D.
Abstract:: Ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta var. murrayana) forests of south-central Oregon have been extensively researched over the last century. However, little information has been reported on overstory composition and stand structure shifts associated with fire exclusion within inter-mixed ponderosa pine and lodgepole pine stands of the...

Beaver ecology in Bridge Creek, a tributary to the John Day River

Creator:: Maenhout, Julie L. (Harper)
Abstract:: The American beaver (Castor canadensis) was nearly extirpated by the late 1800's due to the fur trade. Due to reintroduction efforts, it now occupies much of its former range. Beavers are a keystone species and ecosystem engineers, greatly influencing riparian and instream habitats through selective harvesting of plant materials and...

Establishment and growth of natural and planted conifers ten years after overstory thinning and vegetation control in 50-year-old Douglas-fir stands

Creator:: Nabel, Mark R.
Abstract:: Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...
