Invasive Species Control at GTM Research Reserve Quick Topics

Invasive species are those wild or feral plants or animals that are not native to Florida, but were introduced as a result of human-related activities and have become a threat to natural communities. The best strategy to protect GTM Research Reserve's natural resources from invasive species is prevention.

Feral hogs are the most damaging exotic species. Their rooting is destructive to biological communities and they compete for food with native animals while preying on others. They have also damaged archaeological and historical resources. Hog trapping and installing hog fencing are among the control methods used at GTM Research Reserve.

Other Invasive Animal Species
  • Feral cats.
  • Nine-banded armadillo.
  • Asian green mussels.
  • Golden apple snail.
  • Cuban brown anole.
  • Cuban tree frog.
  • Fire ants.
Feral hogs

The only exotic plants requiring persistent management action are sicklepod, Japanese privet and shrub verbena. These are well under control and require only occasional inspection of wetlands and disturbed lands for new volunteer plants.

Problem or Nuisance Species

Alligators can become a problem if they lose their fear of humans. If that happens, FWC is contacted and the alligator is trapped and removed. The marshes bordering the Guana and Tolomato rivers are breeding sites for native black salt marsh mosquitoes. GTM Research Reserve is partnering with Anastasia Mosquito Control District to study better mosquito control while minimizing damage to GTM Research Reserve's natural biodiversity.
