District Plan Hauraki Gulf Islands Section - Proposed 2006

Appendix 6 - List of threatened and unusual plant and animal species

1.0 Introduction
2.0 Threatened and unusual plant species
3.0 Threatened and unusual animal species

1.0 Introduction

This appendix contains lists of threatened plant and animal species thought to be on the islands as at June 2006. The lists also include plant and animals species that are not threatened, but which are of particular importance or interest. Species that are only found on islands that are entirely Department of Conservation estate have not been included.

Species have been classified by their risk of extinction in order of most threatened to least threatened as follows:

1 - nationally critical

2 - nationally endangered

3 - nationally vulnerable

4 - serious decline

5 - gradual decline

6 - range restricted (ie restricted to a small geographic area)

7 - sparse (very small, widely scattered populations).

Data deficient means that so little is known of the species that its risk cannot be assessed.

The habitats of the plant and animal species listed in this appendix are protected by clause 10c.5.1.2 of the Plan.

For plants, the threat status listed is in the context of the Auckland region, as given by R Stanley, P de Lange, and E Cameron in their 2005 article entitled 'Auckland regional threatened and uncommon vascular plants list' (Auckland Botanical Society Journal 60: 152-157). The threat status of the animals and of the two plant species that are threatened nationally but not within the Auckland region is the most recent national ranking from the Department of Conservation. These rankings are listed in a 2006 publication by R Hitchmough and L Bull entitled 'New Zealand threat classification system lists' (DOC Threatened Species Occasional Publication in press). Both publications used the classifications defined by Molloy et al in their 2002 publication 'Classifying species according to threat of extinction. A system for New Zealand' (DOC Threatened Species Occasional Publication 22).
