Iguana Delicatissima Mortality and Reproduction
The Lesser Antillean Iguana was originally found in the Lesser Antilles from Anguilla to Martinique, but is rapidly being lost from both large and small islands due to a range of factors.As populations continue to decline, life history information on the species remains very limited. During a population assessment for this species from May to December 2012, we collected data on the causes of mortality and endangerment by interviewing 53 local inhabitants and compiling all cases known to staff and volunteers of the National Parks Foundation.
Our results and observations suggest that on St. Eustatius, the interaction of vegetation and geology limit nest site availability to the iguana. Our results further indicate that the sites presently used are vulnerable to humans and their non-native pets, livestock, and invasive weeds.
