  • Shrub reestablishment following fire in the mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana (Rydb.) Beetle) alliance

    Creator:
    Ziegenhagen, Lori L.
    Abstract:
    Currently, the of lack information on shrub reestablishment following fire and the wide variability in rates of recovery have lead to uncertainty in using prescribed burning as a management tool in the mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana (Rydb.) Beetle) alliance. This study examined the recovery of shrub...

  • 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...

  • The use of remote sensing for characterizing forests in wildlife habitat modeling

    Creator:
    Vogeler, Jody C.
    Abstract:
    Spatially explicit maps of habitat relationships have proven to be valuable tools for conservation and management applications including evaluating how and which species may be impacted by large scale climate change, ongoing fragmentation of habitat, and local land-use practices. Studies have turned to remote sensing datasets as a way to...

  • 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...
