  • Examination of imputation methods to estimate status and change of forest attributes from paneled inventory data

    Creator:
    Eskelson, Bianca N. I.
    Abstract:
    The Forest Inventory and Analysis (FIA) program conducts an annual inventory throughout the United States. In the western United States, 10% of all plots (one panel) are measured annually, and a moving average is used for estimating current condition and change of forest attributes while alternative methods are sought in...

  • Comparison and analysis of small area estimation methods for improving estimates of selected forest attributes

    Creator:
    Goerndt, Michael E.
    Abstract:
    One of the most common practices regarding estimation of forest attributes is the partitioning of large forested subpopulations into smaller areas of interest to coincide with specific objectives of present and future forest management. New estimators are needed to improve estimation of selected forest attributes in small areas where the...

  • Predicting urban tree attributes for major species in urbanized areas of the western Pacific states

    Creator:
    Jeroue, Lacey M.
    Abstract:
    Urban forests are an essential green infrastructure of our cities. Due to the proximity of urban trees to more than 250 million people and the grey infrastructure within United States cities, urban forests are uniquely positioned to provide a host of social, environmental and economic benefits. Careful management that maximizes...

  • Empirical modeling of windthrow occurrence in streamside buffer strips

    Creator:
    Drake, Timothy P.
    Abstract:
    Streamside buffer strips provide numerous benefits to stream ecosystems. The buffer strips create shade, provide shelter for wildlife, act as barriers to logging debris during and after timber harvest, and serve as a continued source of large woody debris. Quantifying woody inputs resulting from windthrow provides managers with estimates for...

  • Multi-temporal LiDAR Analysis of Landscape Fire Effects in Southwestern Oregon

    Creator:
    Hoe, Michael
    Abstract:
    Quantitative assessments of post-fire effects are key to improving our understanding of ecosystem resilience. While remote sensing technology has allowed us to assess post-fire landscape effects, we are often limited by the lack of information related to pre-fire forest attributes. As a result, our ability to interpret fire effects in...
