in Northern ProvinceXylosma boulindae is a shrub endemic to the north-western part of Grande Terre in New Caledonia. This species is only known from two massifs: Boulinda and Mé Maoya. Currently, Xylosma boulindae does not appear to be impacted by any specific threat, but could be significantly affected if mining activities were launched on Mé Maoya and Boulinda massifs. With an area of occupancy equal to 20 km² and considering the potential future mining activities on both massifs, Xylosma boulindae qualifies as Vulnerable (VU) D2.
Geographical area
Xylosma boulindae is a shrub endemic to the north-western part of Grande Terre in New Caledonia. This species is only known from two massifs: Boulinda and Mé Maoya.
Population
Population size is unknown.
Habitat
Xylosma boulindae is found in humid forest and shrubland on an ultramafic substrate at an altitudinal range of 900-1,500 m asl.
Threats
Although it occurs in utramafic massifs, Xylosma boulindae does not seems to be impacted by ongoing mining activites. However, future mining development is still a threat on that massifs.
Conservation
Xylosma boulindae is protected by legislation in Province Nord but does not occur in any protected area. It seems important to ensure monitoring of known populations regarding to a possible exploitation of Mé Maoya and Paéoua massifs, which might cause this species to become Critically Endangered.
