This report to the EPA presents two methods for setting stronger ecological performance standards to guide the wetland mitigation process: a watershed approach, and ecological performance standards based on ecological integrity assessment methods. Our ecological integrity assessment method uses a three-level approach to identify a suite of metrics, including Level 1 (remote sensing), Level 2 (rapid field-based), and Level 3 (intensive field-based) metrics. The report provides an overview and ratings for each assessment level, as well as detailed protocols and scorecards for metrics at Levels 1 and 2.
