New listing of the threatened status of New Zealand terrestrial invertebrates
IntroductionDOC seeks submissions about any changes in status of New Zealand terrestrial invertebrate taxa to inform a revision of the lists for these groups in the NZ Threat Classification System. Consultation closed: 30 November 2013.
Consultation closes 30 November 2013
This is a call for submissions about any changes in status of New Zealand terrestrial invertebrate taxa, to inform a revision of the lists for these groups in the New Zealand Threat Classification System.
The current list giving the status of all taxa is here:
- Lepidoptera (XLS, 483K)
- Spider (XLS, 1,137K)
- Land snails (XLS, 1,228K)
- Hemiptera (XLS, 200K)
- Coleoptera list (XLS, 218K)
- Orthoptera list (XLS, 307K)
- Hymenoptera (XLS, 150K)
- Diptera (XLS, 1,140K)
- Minor invertebrate groups including nematodes (XLS, 1,184K)
More explanation can be found in the published papers from the last listing cycle: (Stringer & Hitchmough 20124 and references listed therein).
In 2002 the Department of Conservation developed a new system for classifying organisms according to their risk of extinction (Molloy et al. 20025).
This system allows the classification of conservation status/risk of extinction of all organisms known to occur in a wild state in New Zealand. Endemics, non-endemic natives, migrants, vagrants, and introduced and naturalised species are all included, as are taxa which have not been formally described.
This is not a priority-setting system in the way that the listing of Molloy & Davis (19926, 19947) was, so does not include information on taxonomic distinctiveness, or on human values. It is a resource for priority setting, among other functions, rather than a priority list in itself. Two lists of threatened taxa assessed by these criteria were published (Hitchmough 20022, Hitchmough et al. 20071).
During the course of these listings, opportunities for improvements to the system itself were identified, and as a result a new manual with changed categories and criteria and more explicit procedures has been published (Townsend et al. 20083). These revised criteria were used to generate lists of threatened taxa between 2008-2011 - see Summary of changes (PDF, 745K).
To provide the most accurate information, the list is to be fully reviewed and updated every three years. The time has come to undertake this process again for terrestrial invertebrates and we now wish to gather data to begin the reclassification of taxa under the new criteria. We would be very grateful for any submissions providing information on terrestrial invertebrate species, subspecies, etc. that you consider to be threatened or at risk, or very poorly known but seldom encountered and possibly threatened.
Expert panels will meet to review the classification of New Zealand terrestrial invertebrates, on the basis of information supplied.
Please note that submissions are intended to provide information to the panel, not to lobby for a particular outcome.
