Bayou Portage Preserve
The primary boundary of this 1,137-acre preserve, located in Harrison County, follows the edge of the estuarine marsh located along Bayou Portage. The marsh is dominated by needle rush (Juncus roemerianus) with a mixture of duck-potato (Sagittaria latifolia) and big cordgrass (Spartina cynosuroides). A narrow (1-2 m) fringe of smooth cordgrass (Spartina alterniflora) occurs along the edges of the creeks. This area of marsh is similar to all of those along the margins of St. Louis Bay, including those along the NE and NW shores and the lower reaches of the Jourdan River. A low marsh fringe of smooth cordgrass (Spartina alterniflora) occurs along the creeks. A relatively wide band of high marsh can be found along the upland border and consist of a mixture of salt-meadow grass (Spartina patens), gulf cordgrass (Spartina spartinae)and short needle rush (Juncus roemerianus). The gulf cordgrass (Spartina spartinae) occurs as nearly pure stands (70 % +) in places mixed with Juncus.  A residential area to the east with open septic systems poses a threat to ecological integrity.

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