The first detailed global map of carbon stored in tidal marsh soils highlights their importance for climate action.

Britain’s saltmarshes accumulate carbon more slowly than earlier estimates, underlining the importance of protecting existing carbon stores.

Britain’s saltmarshes store vast amounts of carbon, significantly influencing climate mitigation strategies and national carbon accounting.

Saltmarsh restoration in Britain can significantly enhance carbon storage, but success depends heavily on location and plant communities.

Comparing methods for estimating saltmarsh carbon storage reveals big differences, highlighting the need for accurate measurement strategies.

The Citizen Science project that saw over 100 volunteers gather soil cores from saltmarshes across Great Britain.

Simple observations of plant types and soil conditions can predict how much carbon salt marshes store, aiding climate action.
