Survival of planted Douglas-fir seedlings on severe sites using the paper sheet mulch planting method

Creator:: Bradley, Robert F.
Abstract:: Two studies were undertaken in search of a method or methods which might improve the survival of planted Douglas-fir seedlings on severe sites. The first, or preliminary study involved the planting of 2-0 Douglas-fir seedlings on southerly aspects, using nine techniques, including a control. The second, or main study involving...

Yarding system and carriage development : a case study

Creator:: Sears, James Zolla
Abstract:: In recent years considerable work has been done in the development of improved logging machinery. The word improvement may bring to mind entirely new or improved systems which offer the logger greater mobility and efficient use of manpower. Logging has generally been labor intensive, however, "The need to achieve greater...

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...

An HP-75/HP--86 computer data collection system for recording and displaying logging equipment time studies

Creator:: Campbell, Thomas M.
Abstract:: Time studies of logging equipment are important to determine production rates, calculate logging costs and locate operating inefficiencies. However, using present time study techniques, they are also costly and time consuming to complete. This project will develop a new data gathering and storage technique using the HP-75 portable computer to...

Clearcutting prescriptions based on an environmental classification in the south Umpqua Basin

Creator:: Carkin, Richard E.
Abstract:: Land management techniques are numerous and well known, but knowledge of where and how to use these techniques is often inadequate. Silvicultural methods used by foresters in the Pacific Northwest exemplifies this quandary. Silviculture largely consists of applying standard techniques to various forest stands. Classical silvicultural techniques are not universally...

The production potential of the Ingland-Jones Trailer Alp yarder in thinning young growth northwest conifers: a case study

Creator:: Neilson, Dennis Albert
Abstract:: Results of a recent production study indicate that a four man crew thinning young growth Douglas-fir [Pseudotsuga mensiezii (Mirb.) Franco] with an Iglarid-Jones Trailer Alp can produce 1360 to 1460 cubic feet (38 to 41 cubic metres; 8160 to 8750 bd. ft.,) per eight hour day on slopes of 10...
