Service Description: <DIV STYLE="text-align:Left;font-size:12pt"><DIV><DIV><P><SPAN>Accurate mapping of tidal wetlands is vital for effective conservation and restoration of these valued habitats, and good mapping is key to strategic planning for coastal resilience. Tidal wetlands are defined by regular inundation by the tides; therefore, mapping of tidal wetlands should be based on knowledge of tidal water levels and the land areas inundated by the tides. We developed this tidal wetland mapping following that principle. Our mapping includes areas currently inundated by the tides -- "current tidal wetlands" -- from ocean to head of tide, including the freshwater tidal zone. To assist restoration planning, our mapping also includes "historical tidal wetlands" -- areas that were historically inundated by the tides, but are no longer inundated by the tides due to human alterations to the landscape such as dikes and tide gates. This mapping does not distinguish current from historical (disconnected) tidal wetlands. Note: This subset of data represents the approximate extent of current and historical tidal wetlands for PMEP’s 444 estuaries, excluding “unassociated extents” and “mouth connection areas”. </SPAN></P><P><SPAN /></P></DIV></DIV></DIV>
