Critically Endangered (CR) , assessed in 20/07/2022Eugenia sp.nov. Munzinger 7922 is a new endemic shrub from New Caledonia, only known from Tiebaghi. It occurs in scrubland on ultramafic substrates at an altitude range of approximatively 60 m asl. The main threats are linked to bushfires that contribute to the decline of the habitat quality. Its area of occupancy (AOO) and extent of occurrence (EOO) are both equal to 4 km², while the species is known to exist at only a single location. Therefore, this new species of Eugenia is therefore assessed as Critically Endangered (CR) with criteria B1ab(iii,v)+2ab(iii,v) with a continuing decline of all concerned sub-criteria.
