Towards the Reference Condition Approach 2.0
The Reference Condition Approach (RCA) is used to monitor effects of anthropogenic stressors on aquatic ecosystems worldwide. The RCA was designed to identify the most problematic stressors across large geographic scales (e.g., countries). Regional models predict the biological condition of aquatic ecosystems based on their physical and chemical properties. Comparisons of actual and expected biological communities are used to estimate the relative amount of anthropogenic stress. The tendency is to use these models for more site specific evaluations but the accuracy and precision is often less than desired. Examples of monitoring programs across Canada will be used to illustrate elements of data collection and processing, study design, modelling, reference site selection, and bioassessment that show promise in increasing the accuracy and precision of the RCA. Improvements will increase the utility of existing RCA databases and inform the most efficient ways to accumulate new information to assess stress on aquatic ecosystems.
