Red List Status -

Endangered (EN) , assessed in 24/10/2017

Tectaria kouniensis is a saxicolous fern endemic to New Caledonia, only known from two localities: Ile des Pins and Hienghène (in the northeast of Grande Terre). It grows on calcareous substrate (cave floors or walls) at low altitude. Its area of occupancy (AOO) and extent of occurrence (EOO) are both equal to 8 km². Main identified threats include habitat degradation because of stomping and illegal sampling. This species is therefore listed as Endangered (EN) under criteria B1ab(iii)+2ab(iii).

Geographical area

T. kouniensis is endemic to New Caledonia, where it is known from only two localities : Hienghène (in the northest of Grande Terre) and Ile des Pins.


Two subpopulations (Ile des Pins and Hienghène) have been identified but total population size is not known.


S. insulaepinorum grows on calcareous substrate, such as cave floors or walls.


The main identified threat is habitat degradation by stomping, as well as illegal sampling.


T. kouniensis is not protected by any legislation in New Caledonia and doesn't occur in any protected areas. Since this species has not been seen recently on Ile des Pins, it should be sought after. It is recommended to inform the local Management Committee on the presence of the species in the concerned areas.
