Further research on restored salt marshes is essential to understand the recuperation of natural carbon dynamics and provide insights into short-term effects and a basis for long-term monitoring. In this study, we assess the net CO2 exchange with the atmosphere over a year in a recently restored salt marsh in Trebujena, southern Spain. We measured CO2 fluxes every two months from bare and vegetated sediments that were terrestrialised, under both dark and light conditions, and examined their relationships with the environmental variables measured in situ (i.e. sediment temperature, moisture, salinity, pH, organic carbon, and inorganic carbon). Additionally, CO2 flux measurements were taken on the flooded area at the water-air interface. Our results indicate that CO2 fluxes were significantly influenced by sediment temperature, moisture, and salinity. Bare and vegetated sediments were CO2 sources because the meadow's uptake was insufficient to offset emissions from terrestrialised sediments, suggesting a degraded physiological state of the vegetation. In contrast, the flooded area was a net CO2 sink, suggesting that the recovery of the natural hydrological regime would be advisable to promote the restoration of the carbon dynamics.
