Background information and definitions
This action involves increasing the frequency or duration of flooding by tides in areas planted with marsh or swamp vegetation. Tidal exchange could be facilitated by breaching sea walls or embankments, installing or widening culverts, excavating tidal creeks, or opening/closing sluice gates. Tidal wetlands may be brackish/saline (e.g. mangroves, coastal marshes) or freshwater (e.g. at the upstream end of estuaries, as in the Mississippi, Yangtze, and Elbe rivers; Baldwin et al. 2009).
