Physical characteristics of forest soils after timber harvest and tillage in central Oregon: a case study

Creator:: Litton, Sabrina
Abstract:: This study examined the effects of timber harvest and subsoiling on soil physical properties considered important to forest productivity and hydrologic concerns. Ground based mechanical timber harvesting on some soil types can cause soil disturbance including compaction. These effects in turn can influence multiple important soil physical properties that affect...

Soil compaction and disturbance following a thinning of second-growth Douglas-fir with a cut-to-length and a skyline system in the Oregon Cascades

Creator:: Allen, Marganne Mary
Abstract:: Soil bulk density and disturbance were measured before and after a commercial thinning of 3 0-50 year-old Douglas-fir using a cut-to-length (CTL) and a skyline system on the Willamette National Forest in the Oregon Cascades. A dual-probe nuclear densimeter was used to measure bulk density at four and eight inches....

Exploring Advancements in Rural Equity and Prosperity in the Oregon Labor-Intensive Forest Industry: The Practical Application of Transdisciplinarity and Science Communication

Creator:: Alessi, Gianna
Abstract:: Disproportionate exposure to exploitative working conditions, social marginalization, and a lack of equitable living conditions are among the many issues that migrant Latinx populations face daily in the United States. However, such issues cannot be addressed by relying solely on traditional academic research approaches without the participation and direction of...

Tactical forest planning using the scheduling and network analysis program (SNAP II)

Creator:: Mafera, Thomas E.
Abstract:: Approximately 750 million acres, or one-third, of the total area in the United States is in forest land. The United States Forest Service, a 34,000 person agency of the Department of Agriculture, is responsible for the management of roughly 20 percent of the forest land in the United States. The...

Critique of seven helicopter timber sales with recommendations for improved planning

Creator:: Petaisto, Inga T.
Abstract:: The focus of this study centers around the economic, technical, and environmental effects analysis of seven helicopter timber sales on four different national forests in Oregon and Washington. This paper is a constructive critique of these seven sales based on the author's personal observations and data collected from planning documents,...

Preliminary planning of forest roads using ARC GRID

Creator:: Xu, Shenglin
Abstract:: Forest road planning is importaht in logging operations, because it can affect feasibility and cost of forest operations. Due to rapid advances in computer hardware, GIS software, and remote sensing techniques, computer forest road planning models using GIS are becoming practical. DEM data at 30 meter resolution are common and...

Aerial forest operations : mineral amendment project

Creator:: Cornell, Jennie L.
Abstract:: A helicopter operations problem was studied for a private forest landowner testing an experimental application of minerals on Douglas-fir (Pseudotsuga menziesil) in the Coast Range of Oregon to offset growth reductions from Swiss needle cast disease. A planning approach was needed to minimize costs for transportation and aerial application of...

Managing Douglas-fir Mortality: Case Studies from Western Oregon

Creator:: Campbell, Lewis
Abstract:: An increase in frequency and severity of hot, dry summers has been associated with a dramatic shift in the coniferous forests of western Oregon’s valleys, especially on the privately-owned properties along the low-elevation edges of these valleys. Various conifer species, including Douglas-fir (Pseudotsuga menziesii), are declining in these forests, leaving...

A case study on the utility of multiple, light to moderate intensity silvicultural treatments to accomplish forest management objectives in southwest Oregon, USA

Creator:: Schmidt, Micah
Abstract:: Small, private forestland owners own about 12% of Oregon’s forestland and have the unique ability to implement innovative forest management activities. In southwest Oregon, extreme ecological variability occurs over small spatial scales and requires fine-scale silvicultural treatments that match the precise ecological setting and management objectives of the forests in...

A productivity study and machine selection technique for rubber tired skidders in Tasmania, Australia

Creator:: Wilson, Robert A.
Abstract:: Time study data was collected for two horsepower classes of rubber tired skidders from field operations controlled by Associated Pulp and Paper Mills, Ltd., Tasmania, Australia. A wide range of site and logging conditions were used to produce both production per hour and cycle time predictive equations. The resultant equations...
