Mangrove range expansion is occurring globally, but little is known about how these rapid climate-driven shifts may alter ecosystem C storage. Here, we quantify current C stocks in ecotonal wetlands across gradients of marsh- to mangrove-dominance, and use unique chronological maps of vegetation cover to estimate C Stock changes from 2003 to 2010 in a 567-km<sup>2</sup> wildlife refuge in the mangrove-salt marsh ecotone.
