Thousand Acre Marsh

Thousand Acre Marsh (which is actually about 800 acres) was formerly impounded for rice cultivation on Michaux and Calais plantations. In 1926 Bernard Baruch attempted to put some of Hobcaw’s ricefields back into cultivation, and a twentieth century bank that remains near Thousand Acre is a remnant of that effort.

The Thousand Acre marsh is one of the system-wide monitoring program (SWMP) sites of the Reserve. This area is dominated by brackish plants such as Spartina cynosuroides. Water quality, nutrient and chlorophyll monitoring was initiated at this site in 1993, and has shown that salinity has ranged from 0 to 33.4, with a long-term average of 8.5.
