  • Growth analysis of heterogeneous stands of ponderosa pine and lodgepole pine in central Oregon

    Creator:
    Mainwaring, Douglas B.
    Abstract:
    Basal area and height growth were analyzed for individual trees in uneven-aged ponderosa and lodgepole pine stands in central Oregon. Basal area growth was modeled as a function of other stand and tree variables to address five general objectives: 1) to compare the predictive ability of distance-dependent versus distance-independent stand...

  • Crown structure, stand dynamics, and production ecology of two species mixtures in the central Oregon Cascades

    Garber, Sean M.
    Abstract:
    Knowledge of stand structure, stand dynamics, and production ecology of species mixtures lags well behind that of single-species, even-aged stands. Two mixed-species spacing trials in central Oregon allowed investigation of mixed-species dynamics in a controlled experimental setting. The first site, Pringle Butte, is a mixture of ponderosa pine (Pinus ponderosa...

  • Seedling response to vegetation management in northeastern Oregon

    Creator:
    Lindsay, Amanda A.
    Abstract:
    Northeastern Oregon geology and climate provides moderately productive conditions for forest management and timber production. Although site preparation and planting are commonly used silvicultural practices, little research exists on the efficacy of specific forest herbicides and responses of seedling survival and growth in this region. This research seeks to improve...
