Local watershed monitoring groups use different methods for data analysis and reporting, which results in data that are of variable quality and report cards that are challenging to compare. This project seeks to create uniform sampling and data analysis protocols for non-tidal indicators, by developing consensus among members of the Mid-Atlantic Tributary Assessment Coalition (MTAC). Implementation of the protocols will improve consistency and reliability of data from watershed groups, and will enable direct comparison of results among existing and future groups. This work continues the recently completed protocol for sampling, analysis, and communication of tidal indicators, previously funded by CBT.
