  • Influence of spacing and crown recession on wood quality of intensively-managed young-growth Douglas-fir

    Creator:
    Robbins, James M.
    Abstract:
    Intensive management of young-growth Douglas-fir plantations has emphasized volume growth over wood quality. A better understanding of the variables that affect wood quality is needed so that wood quality and stand yield can be systematically combined into a silviculture program. This experiment utilized two separate experiments to establish the relationship...

  • 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...
