The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.
Current conservation status
- Conservation status of New Zealand mosses, 2014 (PDF, 583.87 kB)
The conservation status of 109 New Zealand moss taxa was assessed using the New Zealand Threat Classification System (NZTCS). Four taxa and one undescribed entity that were not included in previous assessments have been added to the list. The conservation status of only two taxa has changed in this assessment. A full list is presented, along with a statistical summary and brief notes on the changes. This list replaces all previous NZTCS lists for mosses. Authors: Jeremy R. Rolfe, Allan J. Fife, Jessica E. Beever, Patrick J. Brownsey and Rodney A. Hitchmough
- Conservation status of New Zealand hornworts and liverworts, 2014 (PDF, 695.44 kB)
The conservation status of the New Zealand hornwort and liverwort flora is 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 list replaces all previous NZTCS lists for New Zealand hornworts and liverworts which previously had been part of a generic bryophyte conservation status assessment that included mosses.

Plants bright green when fresh, paling to fawn, loosely intricate in a depressed mat. Stems to 20 mm., branched at an angle somewhat less than a right angle, branches simple or forked, mostly bearing 1–2 flagelliform branches, to 5 mm. long and 0.1 mm. broad, with minute closely appressed bifid leaves. Leaves imbricate, very regular, with a narrow hyaline margin all round, narrow ovate 0.35–0.40 mm long × c. 0.20 mm. broad, oblique, ventral margin convex, dorsal margin nearly straight; bilobed, the ventral lobe the larger, triangular, subacute, 0·1 mm. long, to 0.1 mm. broad at base (ca. 5 cells), inclined towards the apex of the stem; dorsal lobe reduced to a tooth or a crenation. Stipules imbricate, medium to comparatively large, subcircular, to 0.2 mm. wide, divided from 1/3-½ into 3 obtuse or acute lobes Cells 10–12 microns, more or less in rows and fairly uniform except in basal area somewhat nearer to the ventral margin than to the dorsal, where they may reach to 18 micrometres. Cuticle minutely papillose showing along the margin of the leaves. No inflorescences seen.
marginatum: From the Latin marginatus ‘edge, margin’, where one colour is surrounded by a very narrow rim of another
