  • 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...

  • Classification strategies for unbalanced binary maps : finding Ponderosa pine in the Willamette Valley

    Creator:
    Riddell, Audrey P.
    Abstract:
    Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...
