Biography

Amy Borde has over 20 years of experience in coastal wetland ecology and restoration. Since 1996, her research has focused on evaluating the interaction of environmental factors and plant communities in seagrass meadows, tidal marshes, and forested wetlands. She applies the findings of her research to better understand complex ecosystem processes, improve restoration success, and to predict potential climate change effects.

Research Interests

  • Lower Columbia River Estuary Wetlands: Amy has been involved in multiple studies at over 80 tidal wetland reference and restoration sites for Bonneville Power Association, the US Army Corps of Engineers, and the Lower Columbia River Estuary Partnership. She has led several wetland ecosystem studies to evaluate conditions and understand the complex interactions driving the spatial distribution, temporal variability, and ecosystem function of these systems. She has collaborated on studies to understand the effect of invasive plant species and to experimentally evaluate control methods. Her restoration studies range in scope from planning and prioritizing restoration projects to monitoring the effectiveness of restoration actions. She also is a primary contributor to the estuary restoration monitoring protocols and is currently part of a team developing methods to use UAVs for automated wetland vegetation community mapping to remotely evaluate wetland habitats and restoration effectiveness. Her breadth of knowledge regarding the effects of hydrologic variability on wetland plant communities is being applied to evaluate potential effects of future climate driven hydrologic changes.
  • Eelgrass Research and Restoration: Amy has conducted research on the factors affecting growth and survival of eelgrass, a critical habitat in PNW estuaries. These studies have included long-term in situ productivity measurements and experiments to evaluate stressor responses. The data from these studies have been used to evaluate the effects of climate driven changes and to improve restoration success. She has also been instrumental in developing and implementing an eelgrass restoration program with the Washington Department of Natural Resources that has included modeling for habitat suitability, experimental planting, large-scale transplanting, and monitoring.
  • GIS Analysis: Throughout her career Amy has utilized spatial analysis tools to improve landscape scale understanding of wetland ecosystems. Applications have been many site-scale analyses in addition to numerous regional studies including an eelgrass habitat suitability assessment in Puget Sound, habitat connectivity and tidal channel complexity within the 235 km complex Columbia River estuary, and historical habitat change analyses in multiple Pacific Northwest estuaries.
