In South Carolina the average home range of boars is 226 hectares, while the average for sows is 181 hectares. The most heavily used habitat types were fresh water marshes and brackish water marshes (Wood and Brenneman 1980, in Wolf and Conover 2003).
In South Carolina, fruits, especially acorns, are the most common food type consumed in fall and winter; herbage and foliage were most common in the spring and roots were most common in the summer. Invertebrates and vertebrates were also consumed, though they were not as important. Use of different types of food, such as woody plants, may be underestimated as when pigs eat roots they chew the root and swallow sap and starches which go undetected in a survey of stomach contents (Wood and Roark 1980, in Wolf and Conover 2003).
