Invasive Species Threat Summary

This Vulnerable forest snail is endemic to and widely distributed in the Lau group in Fiji. Its habitat has been subject to ongoing loss and disturbance on human-inhabited islands though large scale processes such as logging and deforestation for agriculture and on a small scale from shifting garden cultivations to wood harvests. In addition invasive species such as Pacific rats (Rattus exulans), black rats (Rattus rattus), yellow crazy ants (Anoplolepis gracilipes), big-headed ants (Pheidole megacephala), domestic fowl (Gallus gallus), pigs (Sus scrofa) and cattle (Bos taurus) are likely threats to this snail though disturbance of the microhabitat of the forest floor and/or predation.

Invasive Species Management Summary

Surveys to determine the current distribution and population status of this snail are recommended and research is needed to explore options for indigenous snail site/habitat protection. Continued biosecurity measures are critical to prevent the giant African snail (Achatina fulica), predatory rosy wolf snail (a href=http://www.issg.org/database/species/ecology.asp?si=92&fr=1&sts=&lang=EN>Euglandina rosea) and predatory flatworm (Platydemus manokwari) from establishing in Fiji. The giant African has the potential to displace indigenous land snails and has recently been shown to have predatory behaviour (Meyer et al. 2008). The predatory rosy wolf snail is used as a biological control against the giant African snail with resulting devastating consequences for indigenous land snail prey species (Cowie 2001, Barker and Efford 2004).
