As a result of human disturbances, the Hawaiian Islands have seen devastating extinction rates, and today, over half of the described tree snails are thought to be extinct (7). Having suffered from habitat loss, the Hawaiian tree snail is now restricted to just a single location, with a population of less than 1,000 individuals (5). This species first came under threat when the first settlers on the Hawaiian Islands began logging the lowland forests, replacing natural habitats with agricultural lands and cattle ranches. These destructive activities were compounded by the introduction of non-native predators, such as rats and the predatory snail Euglandina rosea, and alien plant species, which overgrow native plant seedlings, limiting natural forest regeneration (2). As a result, the Hawaiian tree snail, listed as a Species of Concern by the United States Fisheries and Wildlife Service, is under severe threat of extinction (8). The survival of this species is also hindered by its slow reproduction rate and the degradation of its habitat by feral pigs and goats (5) (6).
