It was officially designated in 1999.

Invasive and Problem Species
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.
