Wetlands nontidal

X 10" acres of tidal and nontidal wetlands are to be restored by 2010. Also, by 2012, the rate of urban sprawl development of forest and agricultural land in the Chesapeake Bay drainage basin is to be reduced by 30% from the average over 1992-1997. It is too early to determine the level of success achieved by the efforts to clean up Chesapeake Bay. 

The hydroperiod of wetlands is dependent on flow, depth, frequency, duration (the amount of time wetlands are in standing water), seasonality, and frequency of flooding (average number of times wetlands are flooded or saturated). Thus, the hydroperiod of a wetland includes all aspects of water budget (rainfall, evapotranspiration, and subsurface and surface flow) irrespective of the source of the water. The following qualitative definitions have been presented for wetland hydroperiods in tidal and nontidal wetlands (Cowardin et al., 1979 summarized by Mitsch and Gosselink, 2000).
