Tidal wetlands, mangroves and saltmarsh and their upland counterparts; supratidal forests, are important social and economic ecosystems yet are threatened by sea-level rise due to their low coastal elevation. Surface Elevation Tables (SETs) are mechanical levelling devices used in tandem with benchmarks that measure the relative elevation change of wetland sediments (Cahoon et al., 2000). Monitoring elevation change through time provides insight into the vulnerability of these coastal wetlands to sea level rise. Across Australia nearly 300 SETs are being monitored at over 30 sites (Saintilan et al., 2023). Ensuring these are consistently monitored using the same methodology allows for comparison and better management outcomes. The Terrestrial Ecosystem Research Network (TERN) have funded a 3-year project will bring the SET network from discrete projects to a recognisable community of practice around Australia to a network contributing to and recognised as National Research Infrastructure (NRI). Long term elevation monitoring allows for assessment of vulnerability to SLR, carbon burial rates and to better informed management decisions.
