  • Forest Soils and Topography : Decoding the Influence of Physical Site Characteristics on Soil Water and Forest Productivity in Oregon's Coast Ranges

    Creator:
    Rodman, Henry
    Abstract:
    Forest soils and topography have long been known to influence forest productivity in complex terrain such as Oregon’s Coast Ranges. Incorporating physical site characteristics into predictions of forest growth and yield, however, has been problematic because of the high spatial variability of soil properties and the challenges associated with representing...

  • 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...

  • Quantifying Aboveground Biomass for Common Shrubs in Northeastern California

    Creator:
    Huff, Steven
    Abstract:
    Quantifying biomass is important for sustainable forest management. The purpose of this study is to obtain allometric relationships for seven species of shrubs common in northeastern California so that estimates of carbon and fuel loading may be better realized. Although some shrub biomass equations exist, such equations are limited in...

  • Strategies for sampling and estimation of aboveground tree biomass

    Creator:
    Poudel, Krishna Prasad
    Abstract:
    The issue of global climate change and an increasing interest in the reduction of fossil fuel carbon dioxide emissions by using forest biomass for energy production has increased the importance of quantifying forest biomass in recent years. The official U.S. forest carbon reporting is based on the forest biomass estimates...

  • 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...

  • Error propagation in estimating aboveground biomass using terrestrial LiDAR

    Creator:
    Shettles, Michael A.
    Abstract:
    Broad-scale estimates of above ground forest biomass (AGB) are typically produced by applying individual-tree equations to inventory data consisting of measurements from probabilistically or purposively selected trees. The associated uncertainty for these estimates depends primarily on three sources of error that interact and propagate: (1) measurement error, the quality of...

  • Evaluating the accuracy of imputed forest biomass estimates at the project level

    Creator:
    Gagliasso, Donald
    Abstract:
    Various methods have been used to estimate the amount of above ground forest biomass across landscapes and to create biomass maps for specific stands or pixels across ownership or project areas. Without an accurate estimation method, land managers might end up with incorrect biomass estimate maps, which could lead them...

  • Accuracy and suitability of several stand sampling methods in riparian zones

    Creator:
    Marquardt, Theresa
    Abstract:
    Stand structure in headwater riparian areas of western Oregon is highly variable making quantification of structural attributes within these stands difficult. A reliable sampling design is important to characterize and monitor changes in stand structure over time. This study examined sixteen alternatives for sampling live conifers and six alternatives for...

  • 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...

  • 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...
