  • The Waldo Hills Highland bentgrass area

    Creator:
    Fenton, David S.
    Abstract:
    The Willamette Valley in Oregon produces over 90% of the Highland bentgrass seed produced in the United States. Approximately two-thirds of this production comes from a well-defined area on the eastern edge of the Waldo Hills, east of Salem. This concentration seems to be related to a set of physical...

  • Design and implementation of a web-based turfgrass information system

    Creator:
    Wu, Jing
    Abstract:
    A Turfgrass Information and Decision Support System (TIDSS) was developed by international collaborators. In this project, an efficient and effective web-based information system, composed of a Turf Content System (TCS), a Turf Resource System (TRS), and the supporting tools, was developed to support the cooperative efforts. A comprehensive schema of...

  • 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...

  • Western Juniper (Juniperus occidentalis) distribution, Bear Creek Buttes, Deschutes County, Oregon: some possible ecological and cultural influences

    Creator:
    Frates, Dennis Marshall
    Abstract:
    Several environmental and cultural factors were studied to explain the distribution of western juniper (Juniperus occidentalis Hook.) in an area one mile northwest of Millican, Oregon. In the study area juniper grows densely on upper south slopes and only sparsely occurs on upper north slopes. Juniper moisture stress was found...

    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....

  • Exploring the persistence of Oregon white oak in the Willamette Valley

    Creator:
    Juhl, Eli
    Abstract:
    Over the last 150 years, Oregon white oak habitat in the Willamette Valley has been converted to support grass crops, orchards and vineyards, cities, and conifer forests, nearly extirpating it from the Willamette Valley. Yet Oregon white oak offers many ecosystem services to the Willamette Valley and its residents. Recent...
