Red List Status -Vulnerable (VU) , assessed in 26/01/2018
Syzygium baudouinii is an endemic shrub from New Caledonia restricted to the south of Grande Terre, from Ouaménie to Yaté. It is found in wetland and swamp on ultramafic soil between 300 and 700 m asl. The main threats are bushfires that cause habitat degradation and myrtile rusts that can affect some subpopulations. Its extent of occurrence (EOO) and area of occupancy (AOO) are 1,586 and 40 km², respectively, while the number of locations is estimated to be eight. Therefore, S. baudouinii is listed as Vulnerable (VU) under criteria B1ab(ii,iii,v)+B2ab(ii,iii,v) with an estimated decline of the subcriteria concerned.
