Since their colonisation, the Galapagos Islands have experienced a dramatic decline of suitable habitat for land snails, as farming, road and house construction, and eventually tourism, grew (1) (2) (3). Both San Cristóbal and Floreana have been badly affected and each now has more than five bulimulid species categorized as Critically Endangered or Endangered on the IUCN Red List, as well as several previously recorded species that are now extinct (3). Grazing livestock (goats, pigs) and invasive alien plants have also altered the snail’s habitat (3) and, occasionally, the islands have suffered from uncontrolled fires, destroying habitat and snails alike (2). Additionally, introduced predators such as black rats (Rattus rattus) and little fire ants (Wasmania auropunctata) have had a direct impact on land snail populations by feeding on them and destroying their eggs (2). Established populations of the invasive little fire ant are known to exist on San Cristóbal and Floreana (1).
