‘Conservation status of New Zealand indigenous vascular plants, 2012’ was compiled by the New Zealand Department of Conservation and published in 2013.
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below was reassessed using the New Zealand Threat Classification System (NZTCS). A full list is presented, along with a statistical summary and brief notes on the most important changes. This 2012 list replaces all previous NZTCS lists for vascular plants (NZ Plant Conservation Network).
