Note: Data are not directly comparable to those presented in Table 63 because different quantitative methods were used for estimating wetland acreages by type. Coastal wetlands include all wetland areas (in addition to tidal wetlands) shown on FWS National Wetland Inventory maps within counties adjacent to marine waters (excluding Alaska and Hawaii).
