One of four Anegada iguanas that hatched in October 2001 at the CRES facility eyes his surroundings. The Zoological Society of San Diego had the only group of these critically endangered lizards outside their native island habitat, and these four represented the first successful breeding and hatching of this species in a zoological facility. There were only about 300 of these lizards left in the world when CRES researchers Dr. Jeff Lemm and Dr. Glenn Gerber went to the island of Anegada to work with the British Virgin Islands National Parks Trust to try to save the species. As with the ongoing Cuban iguana conservation project, the plan was to breed Anegada iguanas in protected facilities and raise the young until they were large enough not to be eaten by introduced predators on the island—giving them a "head start." They would then be reintroduced, with the hope that the population would increase over time.
