  • Climate, management, and forest type influences on carbon dynamics of West-Coast US forests

    Creator:
    Hudiburg, Tara M.
    Abstract:
    Net uptake of carbon from the atmosphere (net ecosystem production, NEP) is dependent on climate, disturbance history, management practices, forest age, and forest type. To improve understanding of the influence of these factors on forest carbon flux in the western U.S., a combination of federal inventory data and supplemental ground...

  • Vegetation response following thinning in young Douglas-fir forests of western Oregon : can thinning accelerate development of late-successional structure and composition?

    Creator:
    Beggs, Liane R.
    Abstract:
    Across western Oregon, Washington, and British Columbia, forest management practices over the past century reduced the amount of late-successional forest while simultaneously increasing the amount of young (less than 80 years old), managed Douglas-fir (Pseudotsuga menziesii) dominated forests. Recently, concerns over loss of late-successional habitat pushed management objectives on public...

  • Validating songbird habitat relationship models

    Creator:
    Wilson, Dorothy G.
    Abstract:
    Models are commonly used to assess and predict wildlife response to management practices. Model validation is essential if managers are to use them with confidence. Fifteen forest bird-habitat relationship models were developed by biologists using data collected from private forestland in southwest Washington. These models predict species' probability of occurring...

  • Community structure of old-growth Juniperus occidentalis woodlands

    Creator:
    Waichler, Wendy Sims
    Abstract:
    Knowledge of old-growth Juniperus occidentalis woodlands, which occur in central and eastern Oregon, is limited. Wise management of these woodlands necessitates a better understanding of the community ecology. The community structure of woodlands at seven sites in three areas of central Oregon was studied. Measurements taken at nine plots per...

  • An opportunity cost approach to land preservation in the Oregon Coast Range

    Creator:
    Aliski, Leon David
    Abstract:
    This study estimates a range of opportunity costs associated with three land management alternatives for a site in the Oregon Coast Range. A 35,000 acre site was selected which includes a mix of federal and private land ownership and provides significant biological resources. The first alternative examines a plan for...

  • Interactions between near-urban forest management and recreation : a pre- and post-harvest survey

    Creator:
    Balfour, Richard C. D.
    Abstract:
    Forest management has been influenced by many social and political changes, and one of the most prominent is the increasing urbanization of neighboring lands. As a result, forests once relatively far removed from urban areas now share boundaries with residential developments, and receive increasing pressure to provide recreation and other...
