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.

There are a number of species of Chamaecypariums cultivated in New Zealand but the brightly coloured male cones distinguish C. lawsoniana

Reproduces by seed.
Up to 32 seeds per female cone. Estimate that there could be as many as 10,000 cones per mature tree.
