  • Description:
    "Thousand Acre Marsh " ... may best be described as a large, fresh to slightly brackish (salinity 0-6 ppt), highly productive, low level wetland impoundment which has been experiencing a general decline in habitat quality for approximately two decades. The initial high wildlife value which resulted from stabilization of water levels and reduction of salinity has been gradually yielding to the longer term detrimental consequences of impounding and restriction of tidal flow, similar to nearly all of Delaware's wetland impoundments constructed in the 1950's and 1960's, the marsh area is evolving toward a shallow, sediment-laden, open water area, devoid of vegetation important to waterfowl, waterbirds, muskrats and most other wildlife species"--Carter unpublished report.

    "A biological inventory of 1000 Acre Marsh, New Castle County, Delaware, was conducted during the 1993 growing season by the Delaware Natural Heritage Inventory (DNHI). The survey was requested and funded by the Division of Soil and Water Conservation, Department of Natural Resources and Environmental Control to address the biological components of this marsh and any impacts from proposed long term wetland management plans"--Leaf 1.
