Coastal wetlands are naturally resilient to changing sea levels; however, as rates of sea-level rise increase, the interaction between changing sea-level and ongoing human impacts will be a major driver in future coastal tidal marsh stability. My goal is to provide decision makers with recommendations to increase the resilience of the Fraser River delta front tidal marsh communities over the twenty-first century. I conducted a literature review to (1) examine the current knowledge base regarding effects of sea-level rise on tidal marshes and (2) identify current ecosystem-based adaptation strategies for increasing tidal marsh resilience to sea-level rise. Based on this review, recommendations are made for strategies that could be used to increase tidal marsh resilience in the Fraser River delta. Recommendations include (1) initiating delta-wide marsh accretion modeling to assess tidal marsh vulnerability under possible sea-level rise scenarios and (2) implementing sediment augmentation pilot projects for both direct (e.g., layered sediment lifts) and indirect (e.g., mud motor) sediment augmentation strategies to test ecosystem based adaptive management strategies as part of an adaptive management framework.
Bioremediation has gained traction for its sustainable principles. Although, advancements in effectiveness are still needed to enable widespread application. This research has two major components. First, priming fungi could prove to be a useful tool to increase efficiency of white-rot fungi when used to bioremediate petroleum hydrocarbons contaminated soil. This study evaluated T. versicolor colonized in two substrates to test this theory. TPH was extracted from the soils using hexane shaking method, and measured on a CG-MS. The study results were not conclusive, and more research should be conducted to determine if priming white-rot fungi can increase the effectiveness of degradation of TPH in contaminated soils. Second, historical and unethical oil production in Ecuador has left an environmental and human health disaster. The goal of this study was to produce a high-level bioremediation plan that can be used and amended for site specific applications in Ecuador.
