Methods and Materials • I did fire ant mound counts in different areas of the South. • Putnam County, TN • Maury County, TN • Hardeman County, TN • Monroe County, MS • Marshall County, AL • I only surveyed fields of 5 acres or larger and counted the mounds in 100 yard squares. Depending on the size of the field, I took as many counts as possible and averaged the numbers. • Materials: • Truck • Horse • Surveyor’s Flags
Discussion • As I predicted, fire ant abundance was noticeably greater the further south I went. The mounds were also larger, therefore containing more ants. • Research suggests that fire ants could populate all of Tennessee by 2080. (L. W. Morrison, M. D. Korxukhin, et al) • Anywhere north of Tennessee’s northernmost border is considered uninhabitable due to cold temperatures or lack of rainfall. (L. W. Morrison, M. D. Korxukhin, et al)
Conclusion • Fire ants are slowly making their way north. • They can have detrimental effects on native wildlife. • There are many options for control of fire ants, although none are perfect.
