Salt Marsh Community Monitoring

By Tony Curtis & Joe DeVivo

Monitoring Objectives
 Determine the rate of salt marsh accretion or subsidence.
 Determine the status and trends in soil salinity.
 Determine trends in relative sea level rise
 Determine species composition, cover and height.
 Determine trends in marsh extent

We plan to develop and use standardized multi-agency
monitoring protocol." Tony Curtis

How? Surface Elevation Tables

 Rod is installed as a survey-grade benchmark
 Changes in the “whole” salt marsh
 Depth to feldspar
 Changes in accretion or deposition rates
 Tied to land and tidal elevation networks

Surface Elevation Table is a portable mechanical leveling device for measuring the relative elevation of wetland sediments. 

Percisly measure sediment elevation in wetlands to determine rates of elevation change, particularly relative to sea level rise.
