  • Long-term Fuel Succession in the Sagebrush-steppe

    Creator:
    Reis, Schyler Ainsworth
    Abstract:
    Historically fire has been the primary disturbance factor in the sagebrush-steppe. The settlement of the West by Euro-Americans, grazing by domestic livestock, and the concomitant spread of invasive species have altered the historical fire regime. Understanding the long-term vegetation structure and fuel succession of the various sagebrush-dominated communities of this...

  • Effects of wildfire burn severity on soil microbial communitiesand invasive plant species in the Cascade Range of Oregon

    Creator:
    Hebel, Cassie L.
    Abstract:
    Fire suppression in the last several decades has resulted in unprecedented accumulations of organic matter on the landscape, leading to an increase in large, intense wildfires. This study investigated the soil microbial community (using phospholipid fatty acid analysis) across recently burned forests on the eastern slope of the Cascade Range...

  • Tree Vigor Response and Competitive Zone Density in Mature Ponderosa Pine

    Creator:
    Shaw, Randi C.
    Abstract:
    This study explored the relationship of mature ponderosa pine (Pinus ponderosa Dougl. ex Laws) tree vigor and competitive zone density following thinning and fuel reduction treatments. Competitive zone density (CZD) was defined as the total tree basal area (m²/ha) surrounding a given ponderosa pine tree within a 10m fixed radius...
