Innovative Approach to Coastal Condition Indicators

The Pacific Estuarine Ecosystem Indicator Research (PEEIR) group has developed a new generation of indicators to evaluate the condition of California's estuaries. We have also devised practical methods for their integration and application. An essential feature of the PEEIR approach has been to integrate a range of measurements within a suite of resident aquatic species. This approach was developed and tested in California's salt marshes, but it can be applied to other habitat types and geographic regions. These indicators are primarily applicable for management issues related to contaminant exposure, nutrient enrichment, and microbial contamination and are a useful complement to existing techniques in ecological risk assessment.
