  • Operating in an uneven-age management prescription

    Creator:
    Alarid, Steven
    Abstract:
    Forest managers in recent years have begun to re-examine the possibilities of using uneven-age silvicultural systems in the Oregon Coast Range. This increasing interest is being driven by a variety of forest resource nianagement concerns, including wildlife habitat diversity, visual aesthetics, and long-term sustained yield. In an effort to begin...

  • 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...

  • 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....

  • 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...

  • 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...

  • 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...
