Baloghia balansae is an endemic shrub or tree of New Caledonia restricted in the central part of Grande Terre with a small extension in Nodéla and Nétéa. It is found in dense humid forest on volcano-sedimentary and more rarely on ultramafic substrate, from 300 to 500 m asl. The main threats identified are feral pigs (sus scrofa), Rusa deer (Rusa tumorensis) and uncontrolled bushfires. Known from nine locations, its area of occupancy (AOO) and extent of occurrence (EOO) are 48 km² and 1,320 km², respectively. Therefore, B. balansae is considered Vulnerable VU B1ab(iii,v)+2ab(iii,v) with an estimated decline of habitat quality and number of mature individuals.
