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...

Aerial photographs as an aid in preparing a management plan for the Blodgett tract

Creator:: Voorhies, Ray Van
Abstract:: There are approximately 4,000,000 acres of cut-over and burned-over land in western Washington and Oregon which are either non-stocked or unsatisfactorily stocked with young forest growth. This brings about a great need for a quick and efficient method of land examination from which to plan reforestation measures and make up...

Spatial and temporal runoff response to snowmelt, and the influence of geomorphology in a headwater catchment, central eastern Cascades, Washington

Creator:: Alley, David
Abstract:: This report presents a nested gauging study of streamflow variability from three sub-catchments (150-200 ha in area) of the Burns Creek catchment (565 ha) in the Entiat Experimental Forest of central Washington State. We test and reject the hypothesis that headwater catchments of this size are composed of physically and...

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...

FishXing: evaluation of fish passage culvert model and comparision with Oregon Department of Forestry's compliance with fish passage and peak flow requirements at stream crossings

Creator:: Morrissette, Brett A.
Abstract:: FishXing (fish crossing), a computer aided stream crossing culvert model designed to analyze fish passage through culverts was compared with results of an Oregon Department of Forestry fish passage monitoring report. FishXing was created at Humboldt State University through sponsorship from the US Forest Service, USDA, Stream Team, Six Rivers...

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...

SkidPC 2000: a mobility, production, and rut depth simulation program

Creator:: Spong, Ben D.
Abstract:: SkidPC 2000, written in Visual Basic Version 6.0, is an updated version of the 1987 DOS program that calculates the mobility and productivity of ground-based logging vehicles over a ground profile. As in the original program, the user enters the vehicle and operational conditions and the program will calculate the...

Production rates of skyline, balloon, and helicopter yarding systems from gross time study analysis

Creator:: Curtis, Richard James
Abstract:: This paper describes the analysis of data from a three-year gross time study of skyline, balloon, and helicopter yarding systems operating in Western Oregon. Data collection activities were designed and supervised by the Pacific Northwest Forest and Range Experiment Station, U.S.D.A. Forest Service. The specific logging systems studied were running...

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...

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....
