Kelp forests and eelgrass meadows are also of high importance for carbon storage and sequestration, while blue mussel beds and bays and inlets are of medium importance for this service. This is an example of a study that aims to identify, describe and demonstrate the values of ecosystem services in different areas of the Nordic coastal waters. This report focuses on a few regulating services from the ecosystem, particularly the peatlands' contribution to carbon storage and sequestration, and gives us information about how this service is connected to the size of peatlands in different countries.
