Gastrolepis alticola is an endemic shrub of New Caledonia, restricted to the southern massif of Grande Terre. It occurs in altitudinal shrubland on ultramafic substrate at an altitudinal range 950-1,500 m asl. This species does not seem directly threatened but bushfires impact lower areas on those mountains. Its area of occupation (AOO) being estimated to 16 km², Gastrolepis alticola is assessed as Vulnerable (VU) with criteria D2 with the possibility that the evolution of bushfires species could rapidly drive the species to CR.
