  • Photogrammetric uses of a new-generation analytical stereoplotter in forestry

    Creator:
    Kiser, James D. (James Donald)
    Abstract:
    The development of personal computer software coupled to an analytical stereoplotter allows major gains in efficiency and accuracy in a number of forestry related subjects. This thesis describes the operation of a system developed by Carto Instruments. This thesis demonstrates how area estimates might be made in a systematic way...

  • The role of strategic planning in the management of fire-prone western Oregon forests for maximizing terrestrial carbon stocks over a 100-year horizon

    Creator:
    Vanderberg, Michael R.
    Abstract:
    Current frameworks for analyzing forest carbon offset projects in disturbance-prone western forests often fail to address the dynamic nature of carbon pathways through time. They do not account for the probability of loss due to wildfire, which can influence the prediction of carbon storage at the end of a planning...

  • An analysis of technical efficiency and productivity growth in the Pacific Northwest sawmill industry

    Creator:
    Helvoigt, Ted L.
    Abstract:
    The objective of this project was to investigate technical efficiency and productivity growth in the Pacific Northwest sawmilling industry over the period 1968-2002. Productivity growth was decomposed into three components: technical change, efficiency change, and scale efficiency change. In addition, using econometric methods, changes in output elasticities and input substitution...

  • Forest biomass estimation with hemispherical photography for multiple forest types and various atmospheric conditions

    Creator:
    Clark, Joshua Andrew
    Abstract:
    The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...

  • Evaluation of a prototype NIR system for Douglas-fir wood density estimation

    Creator:
    Belart Lengerich, Maria Francisca
    Abstract:
    Forest products companies in the U.S. face vigorous competition from other wood producers around the world and other industries (steel, aluminum, plastics, composites). To be competitive, forest companies need to control costs, sort and allocate logs to the most appropriate markets, and recover more value at time of harvest. Interest...

  • Radiative forcing and forest climate policy

    Creator:
    Thompson, Matthew P.
    Abstract:
    This thesis is comprised of two manuscripts that relate to forest-based management strategies in the context of market-based climate change mitigation policies. The work questions the appropriateness of a singular focus on carbon sequestration given the albedo effect and its possible countervailing climatic impacts. Through a review of salient literature...

  • The economics of carbon sequestration in western Oregon forests

    Creator:
    Im, Eun Ho
    Abstract:
    This study considered regional forest policies for sequestering carbon in existing forests in western Oregon. A model of log markets in western Oregon was employed to examine the impacts of forest policy changes on future carbon stock, harvests, and management activities. A carbon tax program, as a mitigation option for...

  • A comparison of the value of forest plans developed under three levels of detail regarding management intentions

    Creator:
    Hirte, Sarah Rebecca
    Abstract:
    In the field of forest planning, assumptions regarding the appropriate modeling of management behavior, translated through management prescriptions, minimum harvest ages, green-up periods, and other variables are needed if a stand-level optimization process is not used to guide the selection of stand management regimes Forest planners thus generally have a...

    Abstract:
    Resilient water, food, and energy management strategies for an ever-growing population and changing environment depends on our understanding of water and carbon cycles from local to global scales. Fluxes of water and carbon are coupled by photosynthesis and plant transpiration cycles the largest fraction of terrestrial water from the land...

  • Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

    Creator:
    Kopper, Neil H.
    Abstract:
    Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...
