Pycnandra comptonioides is an endemic tree of New Caledonia, growing up to 10 m high. It is known from two subpopulations restricted to the north east of Grande Terre. The species is found in humid forest at an altitudinal range of 100 and 300 m asl. on a mixted substrates in a transition area between micaschist and a streams of serpentinites. The main threats identified are Rusa deer (Rusa timorensis) which contribute to the decline of habitat quality. Its extent of occurence (EOO) and area of occupancy (AOO) are estimated to 8 and 8 km², respectively, while its number of locations is equal to two. Pycnandra comptonioides is therefore considered as Endangered (EN) B1ab(iii,v)+2ab(iii,v) with an estimated decline of the habitat quality and the number of mature individuals.

Conservation

Pycnandra comptonioides is not protected by legislation in New Caledonia and it does not occur in any protected area. This species should be included in the Province Nord legislation for a better protection of the species. It is recommended to inform the Conservatoire d'Espaces Naturels de Nouvelle-Calédonie (New Caledonia natural spaces conservatory) which coordinates the New Caledonian Invasive Species Programme on the presence of the species in the concerned areas.
