Conservation status of vascular plant species in Tāmaki Makaurau / Auckland

Abstract

The conservation status of all known indigenous vascular plant taxa in Tāmaki Makaurau / Auckland was assessed using the New Zealand Threat Classification System (NZTCS). This is the first time Auckland Council has facilitated this assessment. Department of Conservation draft regional guidelines were used and a process outlined by the Greater Wellington Regional Council followed.

A total of 786 vascular plant species were identified as present in Tāmaki Makaurau / Auckland. Two hundred species were assessed as Threatened, 105 as At Risk, four as Non-resident Native (Regional Vagrant or Coloniser) and 88 as Data Deficient. Forty-five per cent of vascular plant species are Threatened or At Risk. An additional 27 species were identified that have become extinct or may have formerly occurred in the region.

Auckland Council disclaims any liability whatsoever in connection with any action taken in reliance of this document for any error, deficiency, flaw or omission contained in it
