Threatened and uncommon plants of New Zealand

Abstract A reappraisal of the conservation status of New Zealand's threatened and uncommon vascular plants is presented. The list comprises 511 taxa (22% of New Zealand's indigenous vascular flora) in the following categories: Presumed Extinct 5 taxa, Threatened 107 taxa (comprising 24 taxa Critically Endangered, 33 taxa Endangered, 50 taxa Vulnerable), Declining 60 taxa, Recovering 17 taxa (comprising 14 taxa Conservation Dependent and 3 taxa undergoing Natural Population Recovery), Naturally Uncommon 204 taxa (comprising 62 taxa rated as Sparse, 17 taxa Vagrant, 125 taxa Range Restricted). Lack of information on the threat status of a further 26 taxa caused these to be listed as Insufficiently Known. Ninety‐two taxa are listed as Taxonomically Indeterminate, being those which probably belong in one or other of the preceding lists but which are currently unnamed or where there are other doubts about their taxonomic status. About half of the Taxonomically Indeterminate taxa are probably threatened. Thirty‐three taxa formerly considered at risk are removed from the threatened and uncommon vascular plant lists. A concordance of plant names is provided.
