The sensitivity of salt marshes and mangroves to RSLR depends on whether they accrete inorganic sediment and/or organic material at rates equivalent to rising water levels  . Otherwise, wetland ecosystems must migrate either inland or upstream, or face gradual submergence in deeper, increasingly saline water  . Ability to migrate depends on local topography, the positioning of anthropogenic infrastructure and structures placed to defend such infrastructure . Submergence drives changes in community structure   and functioning  , and will eventually lead to extirpation of the most sensitive vegetation   and associated animals  . The impacts of storms on wetlands are variable and described in SM3.3.1.
