These data represent surface elevation change (or "Vertical Land Motion of the Wetland": VLMw) and vertical accretion time series collected from a series of created tidal wetland sites in the Tampa Bay watershed, Florida, USA. VLMw was measured using a combination of rod Surface Elevation Tables (RSETs), shallow root-zone SETs, and feldspar marker horizons. Sites were created and planted with saltmarsh vegetation originally, but mangroves naturally colonized the sites over time. These data represent a five year record, and were initiated on 9 sites that spanned an age gradient of 2.4 - 20.2 years at the time of first measurement, but which became 7.3 - 25.1 years by the time of the last measurement included in this data release. We established a reference mangrove forest roughly adjacent to each created mangrove site, and those data are also reported herein. Original data were collected in February 2011, and re-collected in July 2011, January 2012, January 2013, February 2014, February 2015, and January 2016.
