Ecological effects of coastal marsh impoundments: A review

摘要: Many coastal resource managers believe estuarine marshes are critically important to fish and shellfish, not only because of the habitat present for juvenile stages, but also export detritus plant nutrients that consumed in estuary. Concern has been widely expressed diking flooding (impounding) mosquito control waterfowl management interferes with these values marshes. Major changes caused by impoundment include an increase water level, a decrease salinity, exchange marsh water. Alteration species composition is dramatic after impoundment. Changes overall production transport phenomena, however—and consequences changes— may be as great some cases concern about implied.
