Closely related to the Rhinoceros Iguana, the Mona Iguana is restricted to one tiny island lying midway between Puerto Rico and Hispaniola that is a protected natural reserve. Population numbers have been reliably estimated at 1500, however immature iguanas are scarce largely due to predation by feral cats and nest destruction by feral pigs. Current conservation measures include the construction of pig exclosure fences around known coastal nesting sites, and an active headstarting program.

Distribution: Puerto Rico

Size: Males to 535mm SVL Females to 490mm SVL

Status: I.U.C.N. Red List - Endangered They are reproducing successfully but the mortality rate for hatchlings is extremely high.

Legal Status: U.S. Endangered Species Act - Endangered

Priority Activities: Enforce existing laws. The Puerto Rican government has recently restricted visitation to the island. If a program to remove exotic predators and herbivore competitors is initiated, and successful, its continued survival is hopeful. Expand and maintain the fencing program to protect nesting areas. Assess the status of wild populations and habitats in order to develop a conservation strategy. Determine the cause of blindness affecting many adult iguanas.

Number Remaining: Estimated at 1,500
