Editorial statement
Coastal marshes play an important role in climate regulation and ecosystem services. This study provides the first large-scale assessment of carbon storage in Nordic coastal marshes, a region currently underrepresented in global blue carbon datasets. It shows how grazing management and environmental conditions jointly influence carbon storage and vegetation structure.

Short summary
Coastal marshes store high amounts of carbon but remain understudied in Nordic region. We measured organic carbon stored in plants and soil across grazed and ungrazed marshes along environmental gradients. Livestock grazing limited reed dominance, reduced aboveground carbon and altered roots allocation. Soil carbon was mainly controlled by soil properties rather than grazing at large scale. Our results show how grazing and environmental conditions jointly shape carbon storage in coastal marshes.
