Oreogrammitis neocaledonica is an endemic epiphytic fern from New Caledonia, where it is quite widely distributed in the central and northeastern mountain range of Grande Terre. It grows in high or medium elevation dense humid forest on volcano-sedimentary substrate above 500 m asl. Its extent of occurrence (EOO) and area of occupancy (AOO) are 3,434 and 64 km², respectively, and no specific threats have been identified. Therefore, O. neocaledonica is listed as Least Concern (LC).
