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 threat classification 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. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Indigenous. New Zealand: North and Chatham Islands (from North Cape to Lake Taupo and nearby river catchments). Also Australia and New Caledonia.
Coastal and lowland forests in gumland scrub, on forest margins and ridgelines (especially in kauri forest), or in open clay pans within tall forest.
Rhizome creeping, to 3 m long, clothed in slightly spreading scale leaves. Branchlet systems erect, 0.1-1.0 m tall. Leaves spiral to subwhorled, imbricate, appressed or spreading, adnate, dimorphic, green, yellow-green to yellow. Leaves of sterile branchlets linear-lanceolate, attenuate, 2.0-4.5 mm long, spreading. Leaves of sporogenous branchlets ovate-lanceolate, attenuate, 1.0-2.5 mm long; margins membranous, translucent, ciliate around the base. Leaves of central axis (sporogenous and sterile) similar to those of sterile branchlets, but appressed, 4.5-6.0 mm long. Strobili terminal on ultimate branchlets, 10-35 mm long, solitary. Sporophylls imbricate, acute; margins membranous, fimbriate. Description adapted from Chinnock (1998) and Brownsey & Smith-Dodsworth (2000).
None. Easily recognised by the stout, erect, aerial branches which resemble a small conifer. Pseudolycopodium densum could possibly be confused with Austrolycopodium fastigiatum except that, A. fastigiatum is a species of montane habitats (it is never found growing with Pseudolycopodium densum), and the leaves on the branchlets of fertile specimens are not appressed as they are in P. deuterodensum.

Can be grown with some difficulty. Best results have been achieved with plants grown on untreated saw dust.
