Ecological and Physical Description
Old growth forest remnant with American elm (Ulmus americana) and Nuttall oak (Quercus nuttallii), and overcup oak (Q. lyrata) intermediate in importance.
Annual precipitation: 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 inches per month).
Anguilla is 8 miles to the northeast and Holly Bluff is 5 miles to the southeast.
Relatively young Inceptisols of Sharkey-Dowling Association; soil is Sharkey clay, a waxey yellow-brown soil that occurs extensively throughout the bottomlands of the Mississipppi River in MS, AR, and LA.
A northwest–flowing slough runs through the southwest corner of the RNA.
