|Scientific Name:||Araucaria muelleri|
|Species Authority:||(Carrière) Brongn. & Gris|
Eutacta muelleri Carrière
|Taxonomic Notes:||The identity of subpopulations on the Goro Plateau and in the Mamie area is uncertain - they may represent a new taxon in which case this assessment will need to be revised.|
|Red List Category & Criteria:||Endangered B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) ver 3.1|

Its restricted distribution and edaphic specificity mean that its current extent of occurrence is considerably less 1,000 km2. The major subpopulations are severely fragmented and the area, extent and quality of habitat have declined.The principal threats are the expansion of mining activities (e.g., construction of a smelter on Goro Plateau) and an increased risk of fire, even in protected areas such as Montagne de Sources. Several locations/subpopulations contain less than twenty trees and these are likely to disappear in the near future. Regeneration and reproduction is very limited. Some restoration activities have been initiated on the Goro Plateua but these are at a very early stage (Cornu et al 2001).
|Range Description:||The species is known only from small parts of the southern massif and the Goro plateau, New Caledonia. Occurs from 150 to 1,000 m.|

|Population:||The largest subpopulation in Montagne des Sources is estimated to consist of more than 2,000 trees. Most other subpopulations contain less than 200 trees. Although most subpopulations are within 50 km of each other, they are considered to be severely fragmented due to physical and ecological barriers that permit little opportunity for recolonization or genetic exchange.|
|Habitat and Ecology:||Predominantly found in maquis shrubland on ultramafic soils, rarely emergent in rainforest. Growth and regeneration are very slow.|
|Major Threat(s):||Mining developments on the Goro plateau threaten subpopulations in that area. In other parts of its range, including protected areas, it is susceptible to wildfires and an increase in their frequency.|
|Conservation Actions:||The largest subpopulation in Montagne des Sources is within a protected area. Other smaller subpopulations on Mont Koghis and Pic du Pin are also within protected areas.|
