Ecological and Physical Description
Former beach of Mississippi Sound covered by deep white sand. Overstory mostly composed of longleaf pine (Pinus palustris) with scattered individuals of other species.
Annual precipitation is 67.72 in (172.01 cm). Rainfall is generally heaviest during July-September and lightest during October-November.
The nearest weather station is the Saucier Weather Station, 1.3 miles northeast of the RNA.
The subject tract is underlain by the Pliocene aged Citronelle Formation and the Miocene aged Pascagoula Formation and is typical of the Gulf Coastal Plain geologic province. Structural elements in the area are the Higgins anticline to the north and Hancock Ridge to the west. The strike of these formations is generally east–west and their dip is to the south toward the Gulf of Mexico. The Citronelle consists primarily of river terrace deposits of interbedded sand, gravel and clay which are typically brick red in color. Sediments of the Pascagoula Formation consist of interbedded fine–grained silty sands, silts and sandy clays which are usually orange in color.
