Exotic species: a species that has been introduced from another geographic region to an area outside its natural range.
Since our country was first colonized, several thousand foreign plant and animal species and hundreds of animal and plant diseases have established themselves in the U.S. Fifteen percent of these interlopers have become invaders, causing widespread problems that can prove serious and exceedingly costly. They can devastate farms and forests, impede waterways, foul lakes and ponds, negatively affect human health, invade natural areas and replace native species.
With the dramatic increase in the importation, transport, breeding and sale of exotic reptiles and amphibians as pets and the increased importation of tropical plants and fruits (agents of transport), the possibility of exotic amphibians and reptiles escaping and becoming established in Tennessee has increased. Additionally, the deliberate (although illegal) release of captive animals into the wild poses a potential hazard to native ecosystems.
According to the book, The Exotic Amphibians and Reptiles of Florida, there are 40 exotic species of amphibians and reptiles that have established breeding populations in Florida; and about 20 others whose population status is uncertain. The Peterson Field Guide to Reptiles and Amphibians of Eastern/Central North America includes various introduced species that have long established populations not only in the warmer climates of the southern U.S., but also in Ohio and Nebraska. It is only a matter of time before exotic amphibians and reptiles begin showing up in the wild in Tennessee, if they are not already here.
