  • How well do American viticultural areas correspond with the soil classes in Oregon's northern Willamette Valley? A question for the wine industry

    Creator:
    Wood, Douglas T.
    Abstract:
    The specific geography of individual wine growing regions has long been understood to be a significant factor in predicting both a region’s success in producing high quality grapes, and the resulting demand for wines produced from that region's fruit. In the American wine industry, American Viticultural Areas (AVAs) are increasingly...

  • Variations in Alsea River flow: implications for Alsea Spit & inlet stability

    Creator:
    O'Neil, Douglas James
    Abstract:
    Based in part on previous work by this researcher, variables assumed to play a minor part in the process/ response system examined by the OSU Alsea Bay Hazard Study Team (1985-87)--river input and subsequent variations in hydrology--were more completely analyzed for their range of effects on the stability of Alsea...

  • Spatial and Temporal Dynamics of Broad-scale Predictive Models : Influences of Scale

    Creator:
    Hooper, Samuel
    Abstract:
    Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...

  • Change detection of land cover in a meadow landscape : the“Ranches” meadow, Silver Falls State Park, Oregon

    Creator:
    Anderson, Carl G.
    Abstract:
    From a landscape ecology perspective, meadows are often seen as landscapes in transition. Succession and change in meadows may be investigated by considering the physical and anthropogenic factors that influence the landscape through time. What is often unknown is how changes occur and how physical and anthropogenic factors contribute to...

  • The cultural significance of mountain regions : implications for the Calapooya Divide, Oregon

    Creator:
    Starr, Karen J.
    Abstract:
    Altitudinal variations in upland regions of the earth create variable climatic zones and conditions. Plant and animal communities must adapt to these conditions, and when they reach their tolerance limits for environmental conditions at the upper levels of a zone, they cease to exist in the environment. Humans also utilize...

  • Grass seeding as a brush suppressant in Douglas-fir clearcuts - a preliminary study

    Creator:
    DeCourcey, Denis Lawrence
    Abstract:
    Increased demand for wood fiber has necessarily increased the intensity of forest management in recent years. In the Pacific Northwest the release of deciduous vegetation following clearcutting of Douglas-fir is a major problem. Herbicides which have been used in the past to control this brush competition may no longer be...
