Objectives of this project include resampling the SET network in ENP, and upgrading and expanding a spatially explicit geodatabase for the project's data.

Over the past 15 years, the U.S. Geological Survey, Southeast Ecological Science Center, has developed a network of sediment elevation monitoring sites in the southwest coastal portions of Everglades National Park (ENP). Sediment elevation change is monitored by the use of a Surface Elevation Table or SET. Another factor that influences coastal wetlands is disturbance. This may be in the form of storm surges and wind damage from tropical cyclones, and fire and freeze events. A storm surge may have positive benefits by depositing sediments, thus raising elevation, or it could cause erosion of the sediments, thus lowering elevation. Hurricane winds, however, may destroy large tracks of the mangrove forest, which do not necessarily recover. Thus, long-term monitoring of wetland elevation and vegetation dynamics is necessary to gauge restoration success in the coastal Everglades.

Specific objectives:

  • Resample the SET network in ENP.
  • Upgrading and expanding a spatially explicit geodatabase for the project's data.
  • Conduct analyses of the accumulated SET data for the entire period of record.
  • Resample permanent vegetation plots associated with the SETs.
  • Analyze the permanent vegetation plot data to examine patterns of mangrove growth, recruitment, survival, and mortality.
  • Prepare and publish papers in the refereed literature detailing the findings of the work.
