Evaluating the Data and Developing Performance Criteria
In this chapter, the authors discuss the ways to represent and evaluate the data, and ways to use the data to set performance criteria. They demonstrate the methods a manager can use to organize incoming data to track the progress of projects and to develop criteria for the evaluation of future projects. The monitoring reports and other data collected for wetland projects are kept on file by many state and federal agencies. Often the reports are reviewed only to document that the wetlands were monitored as required. They use four different graphs to display the monitoring data: performance curves, descriptive graphs, time series graphs, and characterization curves. Time series graphs are similar to performance curves. Both display levels of function versus time, but in the case of time series graphs, data points are not values for individual wetlands of different ages, but are observations from one wetland sampled over time.
