dc.description.abstractDue to the persistent threat of invasive alien species, and habitat loss and degradation, Turks and Caicos Rock Iguanas currently occupy an area of about 37.1 km2 distributed among approximately 75 small islands with very little gene flow between them. This represents less than 10% of their historic range (500 km2 , >250 islands). Further, islands with abundant iguana subpopulations and no current anthropogenic threats total only 15.6 km2 . The total area of occupancy is estimated at 200 km2 using a 2x2 km grid, overlaying 20 clusters of iguana-inhabited islands. Over the last three generations (42 years), at least 11–20 island subpopulations of iguanas (including some very large islands) have been extirpated. The largest subpopulation is found on Big Ambergris Cay and is currently estimated at 6,000–7,000 mature adults (ca 25% of the total population). However, this represents a decline of 30–40% from this subpopulation's size prior to development in 1995.
