Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Flora Category

Non Vascular - Native

Structural Class

Moss

Distribution

Indigenous. New Zealand: Kermadec Islands (Raoul Island only)

Habitat

Saxicolous on andesite rock and associated saprolite within ravine systems prone to sudden flash flooding.

Threats

Known only from two gatherings made from Raoul island in 2009 and 2011. There are two populations, neither large. This moss seems to be genuinely scarce on Raoul Island and it will probably warrant listing as Nationally Critical when the Bryophytes are next up for threat listing. Both populations are at risk from flooding, and possibly accidental loss through track maintenance
