In Arizona they are saving the Saguaros one RFID tag at a time.

(S)eeing saguaros disappear from federal lands, Saguaro National Park came up with a modern solution: radio frequency chips.

With the territory so vast and little chance of catching thieves in the act, land managers insert tiny chips into cactus bodies so they can track them down if stolen.

“We’ve literally chipped hundreds of saguaros we think are in at-risk areas — the size and location that could put them at a high risk of being poached,” said Paul Austin, chief ranger at Saguaro National Park, who said cactus poaching has declined since chipping began about five years ago.

Saguaros are Carnegiea gigantea of course. Named for the Robber Baron Carnegie, they are the only plant in the genus and no one has the courage to move it to another genus of plants to which they are closely related. Of course, most botanists would refer to Andrew Carnegie as a Philanthropist, which might be why they’ve kept the name.
