They can also significantly attenuate wave energy, raise the seafloor  and buffer storm surges and erosion from flooding  . Additionally, they provide a suite of cultural , provision  and regulation  services  . These services have motivated the implementation of management and conservation strategies of these ecosystems . Blue carbon strategies are relatively new, with many of them experimental and small-scale; there is therefore only limited evidence of their long-term effectiveness. There is also limited information on the potential emission of other GHGs from restored blue carbon ecosystems, although reconnecting hydrological flow in mangroves and restoring saltmarshes are effective interventions to reduce CH4 and CO2  .
