Abstract

The conservation status of Gastropoda, excluding taxa in the genus Powelliphanta and those in freshwater, are listed. Forty-seven taxa are Threatened and comprise 28 that are Nationally Critical, 11 that are Nationally Endangered and eight that are Nationally Vulnerable. A further 259 are At Risk, comprising five Declining, 50 Relict and 204 Naturally Uncommon taxa. In addition, 138 taxa are Data Deficient; no taxa are listed as Extinct. Factors that contribute towards New Zealand landsnails becoming threatened are discussed.
