The Salmon River estuary is a model system for studies of tidal marsh restoration. Previous Sea Grant-supported research suggests that this estuary is on a trajectory toward recovery after re-establishment of tidal flow beginning in 1978. However, both the natural variability of the system and the time needed to fully restore the tidal marshes remain uncertain, indicating the need for continuing assessment of sensitive indicators of wetland status, such as invertebrates.

In addition, this spectacular site, with its history of exploitation and subsequent conservation efforts, is well suited for educating undergraduates and the community at large about estuarine ecosystems and coastal issues. The estuary will serve unique role in training both future biologists and future teachers and serve as a laboratory for an innovative approach in which education and outreach are integrated with scientific research.

Haberman’s project is working to establish a continuing monitoring program for macroinvertebrates and abiotic factors in the Salmon River estuary. The program will assess estuarine recovery, provide authentic research experiences for biology and education majors, create K-12/community curricular materials, and will provide knowledge of the research and associated educational curricula to scientists, managers, educators and community members.
