Tristaniopsis ninndoensis is an endemic shrub from New Caledonia, where it is only known from Mont Ninndo, in the northwest of Grande Terre. This species occurs in shrubland on volcano-sedimentary substrate at around 300 m asl. Known from a single location, its area of occupancy (AOO) and extent of occurrence (EOO) are both equal to 4 km². The main threat is posed by recurrent bushfires in the area. Therefore, T. ninndoensis is listed as Critically Endangered(CR) under criteria B1ab(iii,v)+2ab(iii,v).
Geographical area

Habitat
T. ninndoensis occurs in shrubland on volcano-sedimentary substrate at around 300 m asl.
Threats
The main threat is posed by recurrent bushfires in the area.
Conservation
T. ninndoensis is protected by legislation in province Nord, but it does not occur in any protected areas. This species would benefit from in situ and ex situ emergency conservation actions. It is proposed that monitoring should occur to ensure the persistence of the known population. To ensure the preservation of a viable population, it is recommended to inform the DSCGR (government department overseeing firefighting actions) on the presence of the species in the concerned areas. Moreover, it is suggested to promote its growing in nurseries and use in green space planning, as well as raising awareness on this species amongst local stakeholders.
