As the U.S. Senate prepares to resume debate on immigration reform legislation, Americans concerned about the effects of security infrastructure on wildlife movement across the U.S.- Mexico border should call their senators to remind them that laws including solid barricades imperil the survival of many endangered species in the borderlands region of southern Arizona. At particular risk are jaguar, ocelot, and Sonoran Pronghorn, species which move across wide ranges now being fragmented by border walls.

Regardless of the verbage in an eventual Senate-passed version of immigration legislation, the proposed law will need to be reconciled with a previously-passed House of Representatives reform bill that calls for up to 700 miles of solid barricades. There is great concern that the reconciliation process will not eliminate the excessive provision for wall-building in remote wildlife areas.

Urge your Senators to oppose construction of walls in remote, wild areas of the border, and to eliminate requirements for solid barricades, replacing them with a more wildlife-friendly "virtual wall" using available technology such as unmanned aerial surveillance and motion detectors. Call the Senate switchboard today at 202-224-3121 and ask to be connected to your state's senatorial offices, where you can deliver your message!
