Small fish live throughout the freshwater areas of the Everglades and therefore provide an ideal indicator of desirable system-wide seasonal marsh conditions. The aim of this project was to develop a protocol for evaluating the potential impacts of alternative hydrologic management plans on remote areas of the Everglades using a long-term database of aquatic communities.

This project also closely examined the reliability of modeled hydrologic conditions as expressed by the existing interagency hydrologic models and hydrologic monitoring data using Everglades Depth Estimation Network (EDEN), an interagency database managed by the U.S. Geological Survey. The results of these analyses improved interpretation of ecological models of fish communities dependent on field data collection. To provide assurance that the aquatic fauna databases are managed to a high quality of detail, this project also designed a quality control protocol for the database.
