Figure 3. Number of different invasion pathways of introduced amphibians and reptiles in Florida for each decade from 1860–2010. Introductions via the pet trade began to increase in the 1960s while other pathways declined or stayed the same. Overall, 84% of the introductions were related to the pet trade, 12% to cargo, 3% to zoos, and 1% to biological control.
