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
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – an interim threat classification status has not been assessed by the NZTCS panel.

Further research into the status of Linum monogynum var. chathamicum is needed. Whilst plants with bluish or blue striped flowers have been found in New Zealand proper, DNA data (Heenan et al. 2010) suggests that Chatham Island plants are distinct. Further research is needed, but until such time as this has been done it seems prudent to retain the Chatham Island Linum as distinct from New Zealand plants.
