Description
Summary:The objectives of the New Zealand Threat Classification System (NZTCS) are summarised together with the methods used to classify taxa as Threatened , At Risk , Data Deficient and Extinct . An analysis is provided of the threat rankings of 3838 New Zealand terrestrial invertebrate taxa that were assessed between 2009 and 2011. Overall, 193 taxa were Threatened with 106 Nationally Critical , 30 Nationally Endangered and 57 Nationally Vulnerable . A further 1055 invertebrates were At Risk comprising 35 Declining , six Recovering , 102 Relict and 912 that were Naturally Uncommon . Another 1208 were Data Deficient , seven were Extinct and 1175 were Not Threatened . The remaining taxa examined were classified as either Introduced and Naturalised (190) or Vagrant (11). Factors and attributes that affect the threat status of New Zealand terrestrial invertebrates are discussed.
