Republic (ZooDom) from 1974 to 1994, with an average of 100 babies hatching annually. These efforts included reintroductions of captive-bred "head-started" young to several protected areas in the southwest Dominican Republic, in order to reduce the odds of predation by snakes and introduced carnivorans, such as mongooses or feral cats and dogs. The program has not continued since 1995, due to an administrative change at the zoo. International trade in the species is regulated under the Appendix I of the Convention on International Trade in Endangered Species. Illegal logging, competition from domestic grazers (cows, pigs, goats), predation on young by invasive species, limestone mining, harvesting for the pet trade, hunting for bushmeat, pollution, and wildfires are all manmade threats to the rhinoceros iguana's survival. Captivity The rhinoceros iguana is well established in captivity, both in public and private collections. As of 2007, rhinoceros iguanas were present in captivity throughout the United States (total 39 males, 32 females, and 36 undetermined individuals) at 20 zoological institutions, with an additional 533 animals of unassigned subspecies, reported by seven American Zoological and Aquarium Association institutions. The actual number may be much higher, considering animals kept at European and Asian zoos, and the amount kept as pets in private collections. As a result, the demand for wild-caught animals to supply zoos and the pet trade has been reduced.
