Podonephelium cristagalli is an endemic tree from New Caledonia occurring in sclerophyllous forests. It has a scatered distribution across Grande Terre from Mont Maa to the Plaine Cirey. This species grows on volcano-sedimentary substrate up to 829 m asl. Field observation observed small regeneration of the species sometimes in degraded areas. And it grows on areas impacted by invasive species (Rusa deer) and uncontrolled bushfires. Its extent of occurrence (EOO) and area of occupancy (AOO) are estimated to be 72 and 8,778 km², respectively, but the number of locations is considered to be greater than 10, perhaps more. Therefore, Podonephelium cristagalli is listed as Near Threatened (NT) close to VU B1ab (ii,iii,v)+B2ab(ii,iii,v).
