岛屿生态系统对外来物种的影响高度敏感。非本地入侵的蛇、蜥蜴和两栖动物可以通过捕食、竞争和栖息地操纵将疾病带入本地种群，并产生其他有害影响。美属维尔京群岛位于加勒比海的波多黎各大陆架上，在人类影响和物种引进方面有着悠久的历史。两个物种，绿色鬣蜥(鬣蜥)和红腿龟(地龟)在历史上被引进，并已归化，对当地生态系统几乎没有明显影响。然而，近年来引进了几个高度入侵的物种，事实证明，这些物种在其他地方被引进时产生了严重影响，特别是古巴树蛙(Osteopilus Septentrionalis)、甘蔗蟾蜍(Bufo Marinus)和红耳滑鼠(Trachemys Scripta)。在美属维尔京群岛的所有主要岛屿上都记录了非本土两栖动物的分布，并确定了可能的引入和扩散路线。其他物种仍在确认中，这些物种是通过其他加勒比海港口的货运运抵的。
Island ecosystems are highly sensitive to the impacts of introduced species. Non-native invasive snakes, lizards, and amphibians can introduce diseases into native populations and have other deleterious effects through predation, competition, and habitat manipulation. The United States (US) Virgin Islands are situated on the Puerto Rican Shelf in the Caribbean Sea and have a long history of human impacts and species introductions. Two species, the green iguana (Iguana iguana) and the red-legged tortoise (Geochelone carbonaria) were historically introduced and have become naturalized with little apparent impact to the local ecosystem. Recent years, however, have seen the introduction of several highly invasive species that have proved to have severe impacts when introduced elsewhere, specifically the Cuban treefrog (Osteopilus septentrionalis), cane toad (Bufo marinus), and the red-eared slider (Trachemys scripta). The distribution of non-native herpetofauna has been documented on all main islands of the US Virgin Islands and potential routes for introduction and dispersal have been identified. Additional species are still being identified, having arrived via cargo shipments from other Caribbean ports.
