Red List Status -

Data Deficient (DD) , assessed in 27/10/2017

Gossia kaalaensis is endemic to New Caledonia, with a scattered distribution across Grande Terre, from Mont Kaala to the Tontouta valley. It was found in shrubland and forest between 400 m and 850 m asl. Under current delimitation, this species is insufficiently known, and taxonomic studies are being conducted to describe it. Therefore, for taxonomic reasons, G. kaalaensis is listed as Data Deficient (DD). It should be re-assessed as soon as the official description is published because it is presumed to be threatened.

Geographical area

G. kaalaensis is endemic to New Caledonia. Under current delimitation, it has a scattered distribution from the north (mont Kaala) to the south (Tontouta valley) of Grande Terre.


Population size is unknown.


G. kaalaensis seems to occur in shrubland and dense humid forest between 400 m and 850 m asl.


This species was collected at a site that could be impacted by bushfires. Besides, it may be impacted by myrtle's rust (Austropuccinia psidii).


G. kaalaensis is not protected by any legislation in New Caledonia, but it occurs in one protected area: Aoupinié. Taxonomic studies are necessary to describe this species. Besides, prospection is needed to improve knowledge on its distribution, population size and threat level. Finally, once the formal description is published, the species will have to be re-assessed, because it is presumed to be threatened.
