Ecological/Physical Description:
Physical and Climatic Conditions
Nearest weather station, with distance and direction from RNA: The nearest weather stations are at Anguilla, 8 miles to the northeast and Holly Bluff, 5 miles to the southeast.
Annual precipitation (type, seasonal distribution): The annual precipitation is 53”, fairly well distributed throughout the year, but highest from December to April (5-6” per month) and lowest from September to October (2-3” per month)
Maximum and minimum temperatures: The mean annual temperature is 65°F, with July the hottest month (average 82°) and December and January the coolest (average 43°)
Elevation:
Geology and Soils: The soils are relatively young inceptisols of the Sharkey-Alligator-Dowling Association (Scott and Walton, 1962), poorly drained clay soil formed in slackwater areas and in depressions. Parent material is fine textured alluvium from the Mississippi River. When dry, the soil may form cracks 2.5 to 12.5 cm deep.
Aquatic Features:The site is approximately 2.5 km east of the Big Sunflower River, usually flooded for one to three weeks per year, with a water depth of 1 to 1.3 meters (Johnson and Price, 1959). Several small sloughs pass through the southern half of the RNA, from east to west.
Biological Information
Plant Communities: The dominant species are American elm (Ulmus americana), Nuttall oak (Quercus nuttallii), sugarberry (Celtis laevigata) and green ash (Fraxinus pennsylvanica).
SAF Cover Types:
93 sugarberry – American elm – green ash
At Risk Species: none known
Common Shrub Species: the dominant species are sugarberry (Celtis laevigata) and possum haw (Ilex decidua).
Common Herbaceous Species: the dominant species is greenbrier (Smilax rotundifolia). Other species which showed high importance value are trumpet creeper (Campsis radicans), poison ivy (Toxicodendron radicans), Trachelospermum difforme.
