Performance measures are tools used in Comprehensive Everglades Restoration Plan (CERP) project planning to evaluate the degree to which proposed alternative plans are likely to meet restoration objectives and to assess the success of implemented plans in meeting restoration objectives. Performance measures and their associated targets are also integral components of CERP Adaptive Management.

Performance measures are developed through conceptual ecological models that identify key stressors and attributes of the natural system. Attributes are biological and ecological indicators in the natural system that respond to the effects of stressors. Performance measures for other water-related needs of the system, such as water supply and flood control to meet urban and agricultural needs, are derived from state and federal laws. Development and application of performance measures is a dynamic process that incorporates new scientific understandings and technological improvements. As our understanding of the ecosystem grows, existing performance measures are refined, and new performance measures are developed.
