  • Historical forest succession and disturbance dynamics in Coastal Douglas-fir forests in the southern western Cascades of Oregon

    Creator:
    Merschel, Andrew G.
    Abstract:
    Coastal Douglas-fir (Pseudotsuga menziesii var menziesii) forests are extensive west of the crest of the Cascade Mountains in Oregon and Washington and are renowned for their productivity, biodiversity, and the ecosystem services they provide. Increasing wildfire activity in recent years including the extensive 2020 Labor Day fires, and a warming...

  • Equity in Resilience: Wildfire in the Rogue River Basin

    Creator:
    Sloan, Emma E.
    Abstract:
    Forced removal of Indigenous communities and subsequent colonial forest management have led to landscape homogenization, fuel abundance, conifer encroachment, and, therefore, a loss of forest and fire resilience in the Western US. This loss of forest and fire resilience leads to a loss of social resilience as forested communities struggle...

  • Initial attack fire suppression, spatial resource allocation, and fire prevention policy in California, the United States, and the Republic of Korea

    Creator:
    Lee, Yohan
    Abstract:
    In this dissertation, I combined a scenario-based, standard-response optimization model with a stochastic simulation model to improve the efficiency of the deployment of initial attack firefighting resources on wildland fires in California and the Republic of Korea. The optimization model minimizes the expected number of fires that do not receive...

  • The effects of forest fuel reduction on fire severity and long-term carbon storage

    Creator:
    Mitchell, Stephen Richard
    Abstract:
    Two forest management objectives being debated in the context of federally managed landscapes in the US Pacific Northwest involve a perceived trade-off between fire restoration and C sequestration. The former strategy would reduce fuel (and therefore C) that has accumulated through a century of fire suppression and exclusion that has...

  • Effects of Fuel Reduction Treatments on Surface Fire Behavior in Juniper Woodland Ecosystems

    Creator:
    Williams, Claire L.
    Abstract:
    Juniper (Juniperus spp.) woodlands are native but expanding ecological communities that were historically limited by the natural fire return interval of the sagebrush (Artemisia spp.) steppe. These woodlands are often a mix of pinyon pine (Pinus spp.) and juniper that have increased significantly over the last century. This expansion has...

  • A Microeconomic Analysis of Wildfire Suppression Programs in the Western United States

    Creator:
    Rossi, David J.
    Abstract:
    This dissertation studies the microeconomics of forest fire suppression programs. It starts with an inquiry into the causes of increasing shares of public land management budgets devoted to wildland fire suppression in lieu of hazardous fuel reduction or other pre-fire risk mitigation programs. The first two chapters consider competing economic...

  • An Agent-based Evacuation Modeling of Underground Fire Emergency

    Creator:
    Xu, Yue
    Abstract:
    Increasingly congested surface transportation network in urban areas and grow-ing land values make underground transportation systems more attractive for high-ways (i.e., tunnels) and metro system compared to other options [1]. An underground transportation system can preserve the land above for recreational parks, commer-cial buildings, residential homes, or other purposes while...

  • Communicating the wildland fire message : an investigation of agency outreach strategies

    Creator:
    Toman, Eric Lee
    Abstract:
    Wildfire impacts have increased in recent years. The management response outlined by recent policy initiatives (e.g., the National Fire Plan, Healthy Forests Restoration Act) emphasizes the use of prescribed fire and mechanized thinning to reduce the risk of future fire events. These policies also call for an unprecedented level of...

    Creator:
    Gurung, Manoj
    Abstract:
    Gut microbiota plays an essential role in health and diseases, a fact already established. With the explosive increase in obesity and its main complication, Type 2 Diabetes Mellitus (T2D), there is an immediate need for novel methods of diagnosis, prevention and treatment of these conditions. In the last one and...

    Velasquez, Brianna N.
    Abstract:
    The outbreak of the Coronavirus Disease 2019 (COVID-19) and the restrictions implemented in response to it (e.g., stay-at-home orders, social distancing mandates, business closures) had unprecedented effects on the trucking industry. The pandemic prompted the first significant overhaul of federal hours-of-service (HOS) regulations in over 15 years. Prior to the...
