Additional research is required to determine the carbon sequestration of living shorelines and the potential decline in carbon stored with the age of the wetland (Davis et al., 2015). [...] Due to lack of comprehensive mapping, there are no estimations of tidal salt marsh area on the coasts of the Hudson and James Bays, Newfoundland, and parts of Quebec (particularly the northern shore of the St. Lawrence) (CEC, 2016a). [...] Table 6.2 provides a summary of their findings for tidal wetlands and seagrass meadows, as well as the Panel’s assessment of the quality and applicability of the evidence, and of the assumptions underlying the estimated values. [...] Climate change is also expected to have a strong impact on the input of freshwater and the timing of snow and ice melt in northern Canada (Bonsal et al., 2019), affecting seagrass meadows in James Bay and other areas of the Canadian Arctic. [...] For example, a living dike project in Boundary Bay required the collaboration of three jurisdictions — the City of Surrey, the City of Delta, and the Semiahmoo First Nation — to raise the elevation of a salt marsh along a 250-km stretch of coastline (Wood, 2020).
