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. Authors: Peter J. de Lange, David Glenny, John Braggins, Matt Renner, Matt von Konrat, John Engel, Catherine Reeb and Jeremy Rolfe.

2009 | Threatened – Nationally Critical | Qualifiers: OL, SO
Distribution
Indigenous. Kermadec Islands: Raoul Island. Widespread and common throughout the high islands of the tropical Pacific and also in New Guinea, Northern Australia, Indonesia and Malesia.
Habitat
Saxicolous on rock in ravines and also found growing with other mosses, lichens and liverworts on the upper branches of Kermadec pohutukawa (Metrosideros kermadecensis) on Raoul Island.
Flowering
N.A. - spore producing
Fruiting
N.A. - spore producing
Threats
Only known from two small populations on Raoul Island (Smith’s Bluff and Sunshine Valley) where it was discovered during a five day survey of the south-eastern and western parts of that island undertaken as part of the Kermadec Biodiscovery 2011 Expedition to the Kermadecs during May 2011. A similar survey of the north and north-eastern parts of Raoul Island in May 2009 did not locate this species. Although it seems likely that this species is really a naturally uncommon species which is probably also its world southern limit on Raoul Island. The fact that this moss occupies an area of less than 1 square metre means it qualifies as Nationally Critical
