Introduction: Unintentional (accidentally) Species Notes for this Location:
Osteopilus septentrionalis is commonly known as Cuban tree frog in Anguilla. The Cuban tree frog is reported since the late 1980s. Population of the frog increased explosively in 1999 following an unusually wet year and this species is now found across most parts of the island, usually in areas associated with human activity (Townsend et al., 2000 in Varnham, 2006).
Following appropriate wet weather conditions frogs are expected to colonise almost every suitable habitat on Anguilla. At least some individuals have been accidentally introduced on shipments of plants from Florida. Active dispersal during wet waether, combined with passive dispersal by humans (on vehicles, plants etc) (Townsend et al., 2000 in Varnham, 2006). Management Notes for this Location:
Location Notes:
Anguilla is a xeric island, and its habitat is primarily dry thorn forest, with twenty three salt ponds and marshes, which constitute the only natural surface water (Townsend et al, 2000). Impacts:
Modification of hydrology: Osteopilus septentrionalis is believed to contaminate water, especially cisterns (Anguilla National Trust, 2007).
Reduction in native biodiversity: The Cuban tree frog may have possible effects on native lizards and arthropods, though this has yet to be evaluated (Townsend et al., 2000 in Varnham, 2006). Last Modified: 17/06/2008 9:57:28 a.m.
