Stop the Import of Destructive Exotic Snakes

Highly adaptable, nonnative snakes pose an unacceptable risk as invaders. Through escape or release, these "pet" snakes invade natural habitats where they pose a threat to endangered and threatened species like coqui llaneros and crested toads.

The snakes also pose a public-safety risk: An escaped constrictor snake strangled a two-year-old Florida girl in her crib.

The U.S. Fish and Wildlife Service took a step in the right direction by banning the importation and interstate trade of four invasive constrictors in 2012. But two years later the agency still hasn't acted on the other five invaders that account for 70 percent of the trade -- the reticulated python, DeSchauensee's anaconda, green anaconda, Beni anaconda and boa constrictor.

In the Everglades the introduction of nonnative pythons is thought to have wiped out most of the native mammals, including raccoons, opossums and bobcats. And boa constrictors have invaded Puerto Rico and are displacing native reptiles.

Take action below to help prevent further harm. Urge the Fish and Wildlife Service to add these five invasive snakes to the Lacey Act's list of "injurious" species.
