Endangered (EN) , assessed in 30/10/2019

Tectaria moorei is an endemic terrestrial fern from New Caledonia, where it has a scattered distribution across Grande Terre. It grows in low elevation humid or dry forest on volcano-sedimentary substrate up to 400 m asl. The main threat to this species is habitat degradation caused by bishfires and invasive species (mostly rusa deer). Its extent of occurrence (EOO) and area of occupancy (AOO) are 3,088 and 32 km², respectively, and the number of lications is estimated to be 5. Therefore, T. moorei is listed as Endangered (EN), under criteria B1ab(iii)+2ab(iii).

Geographical area


T. moorei is endemic to New Caledonia, where it has a scattered distribution across Grande Terre, from Pic Toro to Koumac.

Population


Population size is unknown.

Habitat


This terrestrial or saxicolous fern grows in degraded areas in low elevation humid or dry forest on volcano-sedimentary substrate, up to 400 m asl.

Threats


The main threat to this species is habitat degradation, caused by bushfires and invasive species, mainly rusa deer (Rusa timorensis).

Conservation


T. moorei is not protected by legislation in New Caledonia and it does not occur in any protected areas. This species would benefit from ex situ and in situ emergency conservation actions. It is recommended to monitor and preserve known populations in delimited areas, and to inform the local authority responsible for the coordination of the firefighting effort about the presence of the species in the concerned areas. Finally, prospection of the formerly known subpopulations (Mt. Mou, Gatope, the center of Grande Terre) are recommended to confirm the presence of the species and better estimate the size and the state of the population.
