The Ft. Worth Zoo now maintains an Anegada Rock "Headstart" facility in the Settlement. Newly hatched iguanas are caught in the wild, brought to the facility, and raised until they are large enough to be able to defend themselves against the feral cats that are their only predator on Anegada. As of 2016, over 200 iguanas have been released from the headstart program back into the wild. In addition, an annual Iguana Festival is held outside the Iguana Headstart Facility to celebrate the island's native species.
