This is the most widespread Araucaria on New Caledonia. However, the majority of subpopulations, especially those in the isolated northern ultrabasic massifs and the Canala/Poro have been and will continue to be affected by mining activities. Its current extent of occurrence, the fragmentation of the existing subpopulations, a continuing decline in area of occupancy, extent of occurrence and quality of habitat coupled with a projected 30% decline in total population within the next 100 years (three generations is longer than this) means that it meets the criteria for VU.

Habitat and Ecology [top]

Habitat and Ecology:

A. montana is widely distributed in dense and low humid forests and in tall maquis minier throughout most of Grand Terre. It usually occurs on plateaus situated below summit ridges in areas that favour the formation of deep ore bodies just above the bedrock.

Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):35-100

Threats [top]

Major Threat(s): Open cast mining, its associated activities and an increase in fire frequencies are the main threats to this species except in locations in the north east where it is unlikely that mining will occur.

Conservation Actions [top]

Conservation Actions: Currently known from only two protected areas (Mt Panie and Mt Do).
