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.
Keywords New Zealand; threatened vascular plants; uncommon
