Gyrocarpus americanus subsp. americanus is an indigenous tree (growing up from 8 to 20 m high) from New Caledonia. It is mainly found in the northern half of Grande Terre as well as in Walpole island. This species occurs mostly in low altitudinal forest on calcareous substrates, from 1 to 600 m asl. This species was seen at an altitude of 600 m asl at Tendé (Voh) in 2013. Despite having an Area of Occupancy (AOO) and an Extent of Occurrence (EOO) equal to 88 and 22,069 km² respectively, Gyrocarpus americanus subsp. americanus is considered to be a common species in New Caledonia. It is not thought to approach the conditions for listing as threatened under any criterion and is listed as Least Concern (LC).
