Assessment Tool

The assessment tool provides a simple, easy-to-use approach for assessing the condition or "health" of the “degradation of fish and wildlife populations” beneficial use impairment (BUI) in the Lower Green Bay and Fox River Area of Concern (LGBFR AOC). In order to use this tool, one must assess the condition of one, several, or all 22 priority populations that have been identified in the LGBFR AOC by conducting field work. 

The UW-Green Bay project team established a weighting system in order to identify those priority populations that are most critical to and would have the largest impact on the LGBFR AOC if improved in terms of quality (e.g., restoration or enhancement project). Using this weighting system and the newly assessed conditions of each priority population, the tool then calculates a weighted average score ranging from 0 (maximally degraded) to 10 (minimally degraded) that describes the “health” or “ecological condition” of fish and wildlife populations in the LGBFR AOC (i.e., the “degradation of fish and wildlife populations” BUI). Improvements made to priority populations with higher weights will have a greater impact on overall condition. A weighted average is similar to a mathematical average, except that instead of treating each of the values equally, it allows some values to contribute more or less to the overall average than others.
