Graveline Bay Preserve Updated:03/2024

The wetland boundary of this 2,339-acre preserve is Graveline Bay and Bayou. One exception is the exclusion of one major tributary. Graveline Bay and Bayou represents one of few relatively undisturbed estuarine bays and small tidal creeks in Mississippi. The area supports salt marsh, brackish marsh, and several oyster beds. The bay, marsh, adjoining upland forest, and undeveloped beach front near the mouth of Graveline Bayou are an important landing area for neotropical migrant birds. This coastal bay/marsh estuarine system receives only local freshwater runoff and consists largely of mid-level needle rush (Juncus roemerianus) dominated marsh along its entire length. Smooth cordgrass (Spartina alterniflora) occurs largely as narrow (1-3 m) bands along the creeks and bayous. 

Recreational Use:
Boaters and anglers use the area on occasional and seasonal basis for waterfowl hunting (sparingly) and fishing. 

Commercial Use:
Fishing and crabbing

Threats to Ecological Integrity:
To the south are two fairly large failed residential subdivisions. Roads are cut, utilities are in place, but very few houses are built. Oyster beds have been closed by the DMR due to septic tank contamination and limited flushing action of bay. Increase of residential home construction without tie in to city sewer system could have adverse impact on bay. Could also result in increased sediment loading.

Rare/Endangered Species:
Malaclemys terrapin Diamondback Terrapin
Juniperus silicicola Southern Red Cedar
