This dataset provides information on plant sexual reproduction of a clonally-spreading perennial species, Spartina alterniflora. We investigated flowering phenology, potential seed and seedling production, and flower damage in reference and restored sites in southeastern Louisiana. Additional covariates of elevation and soil parameters were used to investigate underlying mechanisms of differences.

These datasets provide information on plant alpha, beta, and gamma diversity, and plant species abundance at several spatial scales for tidal wetlands along a salinity gradient in the San Francisco Bay-Delta and an impounded brackish wetland complex in Suisun Marsh, California. Files include diversity metrics calculated at the patch, site, and region scales, average percent cover of wetland dominant plants at the patch scale, and average percent cover of all wetland plants at the site scale. These data support the following paper: Jones, S.F., Janousek, C.N., Casazza, M.L., Takekawa, J.Y. and Thorne, K.M., 2021. Seasonal impoundment alters patterns of tidal wetland plant diversity across spatial scales. Ecosphere,...

Stress gradients influence many ecosystem processes and properties, including ecosystem recovery from and resistance to disturbance. While recent analytical approaches have advanced multivariate metrics of ecosystem resilience that allow quantification of conceptual resilience models and identification of thresholds of state change, these approaches are not often translated to landscape scales. Using natural and restored salt marshes in Louisiana, USA, we quantified plant community recovery and resistance metrics along flooding stress gradients. n‐dimensional hypervolumes of plant community biomass and structure were simulated using field data collected from disturbance‐recovery experiments. The relationships between...

These datasets provide: 1) field-collected biomass and structural attributes for coastal salt marsh in the Port Fourchon area, Louisiana; 2) simulated biomass and structural attributes along flooding gradients using mixed model regression outputs; and 3) resilience metrics calculated using multivariate hypervolumes along with potential environmental covariates of resilience metrics.

Location data with corresponding habitat class (managed vs tidal marsh) and habitat type (permanent pond, seasonal pond, channel, or marshland) for waterfowl utilizing the Suisun Marsh region of California with species, sex, season and date information. These data support the following publication: Casazza, M.L., McDuie, F., Jones, S., Lorenz, A.A., Overton, C.T., Yee, J., Feldheim, C.L., Ackerman, J.T. and Thorne, K.M., 2021. Waterfowl use of wetland habitats informs wetland restoration designs for multi‐species benefits. Journal of Applied Ecology, 58(9), pp.1910-1920. https://doi.org/10.1111/1365-2664.13845.
