Coastal vegetated ecosystems are vulnerable to harm from multiple climate-induced and non-climate drivers, and together these have reduced wetland area globally   and endangered the services provided by these ecosystems . Loss of coastal vegetated ecosystems changes biodiversity , increases risk of damage and erosion from SLR and storms  and impacts provisioning . These changes also strongly determine the quantity and longevity of blue carbon storage  . Specific site characteristics and ecosystem responses to climate change will determine future local blue carbon storage or loss  . For instance, poleward migration of mangroves to areas dominated by salt marshes is expected to increase carbon
