Parsonsia catalpaecarpa is an endemic liana of New Caledonia, restricted to the far north of the main land (Grande Terre), at Koumac, Ouégoa and Poum region as well as in Belep island. It occurs in scrubland (maquis) and forest on ultramafic and non ultramafic substrates at an altitude range of 20-600 m asl. The main threats are the mining activities at Tiebaghi, uncontrolled bushfires and rusa deer (Rusa timorensis) that contribute to the decline of the habitat quality and the number of mature individuals. The population is not known. Its extent of occurrence (EOO) and area of occupancy (AOO) are estimated to be of 1,784 km² and 56 km² with an estimation of eight locations. Parsonsia catalpaecarpa is therefore assessed as Vulnerable (VU) with criteria B1ab(ii,iii,v)+2ab(ii,iii,v) with a continuing decline of all the concerned criteria.
