Range DescriptionPuerto Rican bank endemic. Known from small small scattered subpopulations in Puerto Rico (PR); St John, St Thomas (US Virgin Islands); and Virgin Gorda (British Virgin Islands). The largest subpopulation has been reported from St Thomas to cover an area of approximately 50 acres. Other subpopulations exist as scattered individuals at three sites on Puerto Rico, two on St John and a single site in Virgin Gorda.
The total population was estimated to be between 300-350 in 1988 for the US Recovery Plan with the largest subpopulation estimated at 250 individuals on St Thomas, approximately 50 on St John with scattered individuals on Puerto Rico. The Virgin Gorda subpopulation was unknown at that time. Since then habitat has been fragmented and lost and mature individuals have been lost from all sites. The St Thomas site has been subdivided and sold for residential development. The Virgin Gorda subpopulation has been documented, but there is a need for an up-to-date census of the PR and USVI sites. However, the current global population is likely to be less than 300 mature individuals, and may be close to meeting the criteria for Critically Endangered.
