Regrettably, the major threats facing the Hispaniolan ground iguana are habitat degradation and loss as a result of human activities, which include logging of hardwoods, harvesting for charcoal production and fuel wood, over grazing and trampling by free-ranging livestock, mining of limestone, and illegal collection of live cacti for local and international trade. Additionally, this iguana is threatened by local subsistence hunting and predation from introduced carnivores such as dogs, cats, and mongooses. Hunting for Hispaniolan ground iguanas for food and trade has increased gradually since the mid 1970s, this species at one time being served at oriental restaurants in Santo Domingo as a speciality dish (1).
International trade in the Hispaniolan ground iguana is controlled by its listing under Appendix I of the Convention on International Trade in Endangered Species (CITES) (3). Compliance with CITES trade regulations is largely effective, although occasional smuggling of animals across the Haitian border does still occur. Enforcement of national protective legislation in the Dominican Republic has improved in the last few years, but fails to go far enough, since clearing of natural habitat for development is neither being prevented nor regulated and illegal hunting for food and the local pet market continues (1). However, the Isla Cabritos range, which used to be intensively exploited for hardwood cutting, charcoal, and livestock grazing, has undergone extensive natural regeneration in the last 15 years, and improved protective management since 1992 has meant present conditions there are stable (4). Indianapolis Zoo has had a small but successful captive breeding programme, although survivorship of young has been low (1), and there are plans to re-establish new breeding colonies at both the Parque Zoologico Nacional (ZooDom) in the Dominican Republic and the Indianapolis Zoo (4). The establishment of local educational awareness campaigns to try to reduce illegal hunting, the strengthening and enforcing of protective legislation, and the implementation of research, monitoring and recovery programmes will be essential in guiding effective conservation efforts in the future (2).
