Tidal wetlands support plant communities that facilitate carbon storage, accrete soil, and provide habitat for terrestrial and aquatic species. Climate change is likely to alter estuaries through sea-level rise and changing precipitation patterns, although the ecological responses are uncertain. We were interested in plant responses to physiological stress induced by elevated water salinity and flooding conditions, which may be more prevalent under climate change. . We used a greenhouse experiment and factorial flooding (1, 12, 24, and 48 % time) and salinity (0, 5, 15, 30 PSU) treatments to evaluate the productivity responses of three emergent herbaceous species (Carex lyngbyei, Triglochin maritima, and Argentina...

The sensitivity of tidal marshes to environmental changes that result from sea-level rise or drought conditions is uncertain. We used a controlled greenhouse experiment and factorial flooding x salinity treatments to explore the differential responses of three tidal marsh plant species. Each species exhibited unique responses, with negative responses to increased salinity and longer flooding, but only limited evidence for interactive effects. These data support the following publication: Buffington, K.J., Goodman, A.C., Freeman, C.M. and Thorne, K.M., 2020. Testing the interactive effects of flooding and salinity on tidal marsh plant productivity. Aquatic Botany, p.103231.
