National Park. There are moderately dense populations in the southeastern region of Haiti and its offshore islands, including the brackish lake of Étang Saumâtre, as well as the Dominican hypersaline Lake Enriquillo and its lake island, Isla Cabritos. Populations in Haiti are even more endangered due to deforestation, poaching for bushmeat, and human clearing practices. In general, the iguanas are found most abundantly in (although not restricted to) scrub woodland in Hispaniolan dry forests, which are characterized by xeric, rocky habitats of eroded limestone in coastal terraces and lowlands of the mainland, and several offshore islands and small cays in a variety of subtropical life zones and habitat types. The biome that the rhinoceros iguanas live in are ones that receive very little rain with little trees and shrubs. This species has been known to exhibit phenotypic plasticity like other iguanas. While historically present near coastlines, human activity and introduced predators have forced rhinoceros iguanas inland. An individual was photographed on May 4, 2008 on Limbe Island in northern Haiti. It had been caught by a group of fishermen from Bas-Limbe, Bord de Mer village. The rhinoceros iguanas caught on Limbe Island are illegally eaten by the local population. This sighting represents a new area previously not thought to be in the range of C. cornata. Aside from Hispaniola and its surrounding islands, the rhinoceros iguana was previously found on Navassa Island (with an endemic subspecies: C. c. onchiopsis), but was extirpated there. Behaviour Rhinoceros iguanas, like most members of Cyclura, are usually docile and well-tempered. Although quick to flee when attacked or threatened, they will aggressively attack by biting and repeatedly striking with their thick tail if cornered. Diet The rhinoceros iguana, like most Cyclura species, is primarily herbivorous, consuming leaves, flowers, berries, and fruits from different plant species. A study in 2000 by Dr Allison Alberts of the San Diego Zoo revealed that seeds passing through the digestive tracts of Cyclura species germinate more rapidly than those that do not. These seeds in the fruits consumed by cycluras have an adaptive advantage by sprouting before the end of very short rainy seasons. The rhinoceros iguana is also an important means of distributing these seeds to new areas (particularly when females migrate to nesting sites) and, as the largest native herbivores of their island's ecosystem, they are essential for maintaining the balance between climate and vegetation.
