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...

Overcoming the obstacles of effective photogrammetric mensuration

Creator:: Farnsworth, Blake Templeton
Abstract:: This paper includes a literature review of the methodologies invoked to surmount difficulties inherent with aerial photograph mensuration. The synopsis of early achievements is followed by a more intensive examination of experimental studies of the last decade, particularly the work on controlled scale photography. This report on the pursuit of...

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...

Road surface runoff for the Oak Creek watershed: the influence of hillslope and road characteristics

Creator:: Ellingson, Kami S.
Abstract:: Understanding how forest roads interact with hillslope hydrology by intercepting and/or rerouting storm runoff will better enable land managers to reduce erosion related to forest roads. Watershed scale knowledge of how culvert runoff response varies across the landscape would provide valuable information to those individuals designing and maintaining forest road...

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...

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...

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,...

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....

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...
