Objective:
The Investigator is using EMAP hydrogeomorphic (HGM) data to demonstrate the use of probability surveys to extrapolate measures across a defined area (the Delmarva Peninsula). He plans to use data from these surveys to develop quantitative techniques to [1] quantify the relative risk of poor wetland condition associated with multiple stressors and [2] quantify proportionate loss of ecosystem function and services in terms of wetland area. He will combine relative risk analysis with the survey’s probability design to develop a comprehensive assessment of the relative importance of multiple stressors. He will also combine the HGM data with the probability survey data to calculate the proportion of the regional wetland area that has functional loss, and, by knowing the total valuation of the ecosystem service associated with each function, estimate the value of lost ecosystem services.
Progress Summary:
Work is on schedule and within scope. Grantee is meeting milestones and has made progress toward outcomes. No significant problems were noted. This grant was changed to a cooperative agreement in May 2010; this arrangement will allow the PI to work with Dr. Mary Kentula at NHEERL-WED, one of the technical leads for the NWCA, to get access and advice about the data. Dr. Kentula’s expertise with the NWCA data is essential in order to fully understand the NWCA survey design and sample weighting process, field sampling process, metadata, and overall data QA and variable selection in order to correctly interpret the results of our relative risk analysis. In addition, she can provide expert input to the relative risk analysis to help revise and improve the final product. The PI anticipates that any publication of the NWCA relative risk work would be done in collaboration with Dr. Kentula. Other EPA cooperators include Amanda Nahlik and Rich Sumner.
Economics work is ahead of schedule. The investigator met last month with colleagues in Delaware to discuss GIS, sample site locations, and data analysis. He also presented a talk on activities related to this project. . (Separate note: Mary Kentula at NHEERL-WED had remarked earlier during the SWS meeting noted that Dr. Herlihy had already discussed ideas for collaboration with her.)
