Syzygium boulindaense is an endemic sub-shrub of New Caledonia, restricted to the north of Grande Terre. It is found in shrubland and transitional vegetations on volcano sedimentary and ultramafic substrate, between 950 and 1,100 m asl. This species does not seem directly threatened because of its altitudinal habitat. S. boulindaense is considered Vulnerable (VU) using criteria D2 because of its small area of occupancy (AOO) being estimated to 16 km² and the potential impact of climate change, mining activities (past and future mining projects of Boulinda and Tchingou) and feral pigs (Sus scrofa).

Geographical area


S. boulindaense is endemic to New Caledonia and it is restricted to the north of Grande Terre, from la Dent de la Poya to Tchingou massif.

Conservation


This species is not protected by legislation in New Caledonia and it does not occur in any protected area. This species should be included in the regional legislation for a better protection of the species. And it is recommended to improve the knowledge of the species (prospections, more herbarium specimens) to better estimated its distribution and its status.
