I am a Hunter. Why should I care about invasive species?

Cogongrass, an invasive grass from Asia, is considered “the seventh worst weed in the world”. This species is widespread in Florida, Alabama, and Mississippi and is now beginning to spread in Georgia, South Carolina, and Tennessee. Cogongrass is capable of displacing entire communities of native plants and the wildlife which depend on them. The leaves of cogongrass are extremely unpalatable to native wildlife due to the high silica content. Large infestations can become so dense that many smaller animals find it difficult to travel through them. Large dense infestations also diminish quality brood-rearing habitat for quail and turkeys.

Feral hogs, although challenging to hunt, can cause a wide variety of problems for hunters in the South. Hogs are omnivores and will eat almost anything, including eggs and chicks of ground-nesting birds, such as turkey and quail. Hogs also directly compete with native wildlife for forage. Acorns, a preferred food of hogs, are a significant part of the diet of deer, bear, turkeys, and ducks. Hogs are wallowers and rooters; these activities can destroy water holes utilized by other wildlife. Feral hogs have also been shown to spread brucellosis to humans and livestock.

Red imported fire ants, as anyone from the South knows, are extremely aggressive and have a powerful sting. Pustules that result from fire ant stings are irritating and can cause permanent scarring. Ground nesting birds, such as quail and turkey, are also greatly impacted by the presence of the red imported fire ant. Fire ants have been shown to attack bird and reptile eggs, juveniles, and adults. Red imported fire ants have been shown to reduce bobwhite quail chick survival and, in one study, 38% of chick deaths were attributed to fire ant stings.

Redbay trees are important to the wildlife of the South. Deer eat the fruit and leaves. Fruits are eaten by turkey and quail. A high rate of mortality in redbay trees has been reported in Georgia, South Carolina, and Florida. The cause of the mortality was linked to a fungus (Ophiostoma sp.) that is carried by the redbay ambrosia beetle, an exotic beetle from Asia. New trees can also be infected by the movement of infected wood to new areas. Once a tree is infected it will wilt and die within a few weeks to months. The beetles and fungus can also infest sassafras and avocado trees.


I am a hunter. What can I do to help prevent the spread of invasive species?

  • Use native plants for wild game food plots. Studies show game has a higher survival rate in the wild when using native plants for food and cover.
  • Clean your boots, hunting gear, truck bed, and tires after a hunting trip to avoid spreading non-native seeds, insects, or spores to a new location.
  • Never move firewood. Instead, buy or use firewood that is close to your campsite.
  • Learn to identify the invasive species common to your area.
  • Report any sightings to your county extension agent or to EDDMapS.org
