    Description

    In Puerto Rico, the Green Iguana, Iguana iguana, is considered an introduced and invasive species responsible for annual losses estimated in millions of dollars to local governmental and private sectors. The purpose of this study was to use GAP analyses to generate habitat distribution models for Green Iguanas in Puerto Rico. The two models had 79.7% and 88.4% predictability, respectively. The second model, which included road corridors as a habitat widely known to be used by iguanas for dispersal, basking, and mating displays, might have overestimated the Green Iguana’s distribution. The use of one model over the other should be evaluated on a case-by-case basis, depending on habitat type. These habitat modeling and mapping efforts should be repeated periodically as new distributional records are obtained and the land-cover changes to provide land managers an updated distribution of this species in the islands.
