Abstract
A reappraisal of the conservation status of New Zealand's threatened and un common vascular plants is presented. The list comprises 511 taxa (22% of Ne w Zealand's indigenous vascular flora) in the following categories: Presume d Extinct 5 taxa, Threatened 107 taxa (comprising 24 taxa Critically Endang ered, 33 taxa Endangered, 50 taxa Vulnerable), Declining 60 taxa, Recoverin g 17 taxa (comprising 14 taxa Conservation Dependent and 3 taxa undergoing Natural Population Recovery), Naturally Uncommon 204 taxa (comprising 62 ta xa rated as Sparse, 17 taxa Vagrant, 125 taxa Range Restricted). Lack of in formation on the threat status of a further 26 taxa caused these to be list ed as Insufficiently Known. Ninety-two taxa are listed as Taxonomically Ind eterminate, being those which probably belong in one or other off he preced ing lists but which are currently unnamed or where there are other doubts a bout 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 conc ordance of plant names is provided.
