Camille L. Stagg Ken W. Krauss Donald R. Cahoon Nicole Cormier William H. Conner Christopher M. Swarzenski 2017 Vector Digital Data Set (Point) and tabular data (csv) https://doi.org/10.5066/F7W66HXB We assessed the resilience of wetlands to sea-level rise along a transitional gradient from tidal freshwater forested wetland (TFFW) to oligohaline marsh by measuring processes controlling wetland elevation. We identified fundamental differences in how resilience is maintained across wetland community types, which have important implications for management activities that aim to restore or conserve resilient systems. These data were used to identify processes that contribute to resilience of coastal wetlands subject to rising sea levels and to determine whether the relative contribution of these processes varied across different wetland community types. 2009 2014 ground condition Complete Irregular -81.15849459 -79.089969903 33.569861584 32.153122271 None accretion coastal wetlands elevation change oligohaline marsh resilience sea-level rise tidal freshwater forested wetland wetland RSLR USGS Metadata Identifier USGS:5820c66de4b080404e711965 Geographic Names Information System (GNIS) South Carolina Waccamaw River Georgia Savannah River None.

We adopted the following statement regarding data archiving and sharing from Wright et al. (2004): "The authors believe that the archiving and sharing of large datasets is important for advancing ecology as a discipline. At the same time, for data sharing to be successful and sustainable, it is imperative that all those involved in data acquisition, archiving and use do so in an ethical manner. In particular, we believe that those individuals whose time, efforts and intellect designed and created the studies are acknowledged appropriately." Text in quotation from: Wright, I. J., P. B. Reich, M. Westoby, D. D. Ackerly, Z. Baruch, F. Bongers, J. Cavender-Bares, T. Chapin, J. H. Cornelissen, and M. Diemer. 2004. The worldwide leaf economics spectrum. Nature 428:821-827.
