The impact of invasive species on reptiles and amphibians
Prepared by Dr. Jeffrey E. Lovich, USGS, Biological Resources Division, Department of Biology, University of California, Riverside
Native amphibian and reptile populations worldwide are under threat from exotic invasive species of plants and animals, including other reptiles and amphibians. As habitats are changed and plant community organization is modified by exotic species, delicate relationships between plants and animals are altered or eliminated. For the most part, the impacts of exotic species on herps have been negative.

Impact of invasive exotic animals on native reptiles and amphibians
As a group, reptiles and amphibians have been very successful as invaders. Prior to 1978, 75 exotic species were introduced into the United States in numbers sufficient to allow establishment (Smith and Kohler, 1978), including some 50 species in Florida alone (Wilson and Porras, 1983). The rate of introduction of exotic reptiles and amphibians into South Florida was fairly constant from 1940-1958. However, from 1958-1983 the rate of invasion increased three-fold (Wilson and Porras, 1983).
