  • Understory vegetation effects on soil nitrogen and soil carbon in thinned and unthinned Douglas-fir forests

    Creator:
    Geyer, Eric A.
    Abstract:
    The optimum goal of forest management is to foster long-term productivity and ecological integrity while maintaining or increasing short-term growth and yield through sustainable practices. Understory vegetation plays a definite role in forest functions through nutrient cycling and habitat provisions. The objective of this study was to determine how salal,...

  • Soil carbon and nitrogen in old-growth forests in western Oregon and Washington

    Creator:
    Remillard, Suzanne Marie
    Abstract:
    Soil organic carbon (SOC, kg C m-2) is an important component in evaluating global C stores. The nitrogen (TN, kg N m"2) cycle is closely linked to C and understanding its role is also important. Contents and distributions of SOC and TN in soil profiles, to 1-meter depth, were estimated...
