This is a call for submissions about any changes in status of New Zealand freshwaterinvertebrates, to inform a revision of the assessments for this group in the New Zealand Threat Classification System.

In 2002 the Department of Conservation developed a new system for classifying organisms according to their risk of extinction (Molloy et al. 2002 (PDF, 574K) 2).
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 (1992 3, 1994 4) 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 2002 (PDF, 622K) 5, Hitchmough et al. 2007 (PDF, 471K) 6).
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. 2008 (PDF, 478K) 1). These revised criteria were used to generate lists of threatened taxa between 2008 and 2011 and again between 2012 and 2014.
To provide the most accurate information, the list is to be fully reviewed and updated every five years (previously every three years). The time has come to undertake this process again for freshwater invertebrates, and we now wish to gather data to begin the reassessment of the status of these taxa. We would be very grateful for any submissions providing information on 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 these groups, on the basis of information supplied.
