Taxonomy
Common name :

Vulnerable (VU) , assessed in 03/07/2017Protected species -
in Northern Province
The current extent of of occurrence is estimated to be 6,666 km2 while the area of occupancy is 236 km2. Herbarium records from sites that no longer exist indicate that it was formerly more widespread. Nine locations have been identified and within each of these there has been a decline in the area of occupancy, the quality of habitat and the number of mature individuals. The total population for this species is estimated to be around 10,000 mature individuals. As the number of locations exceeds the threshold for Endangered, and as the population is not severely fragmented, an assessment of Vulnerable under Criteria B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) is the most appropriate.
Geographical area
Agathis moorei (including A. corbassonii) occurs in small subpopulations scattered throughout the northern half of the main island of New Caledonia, at altitudes ranging from 30 to 850 m. The current extent of occurrence is estimated to be 6,666 km2. Herbarium records indicate that it was formerly more widespread.
Population
Population size is not precisely known. The total population for this species is estimated to be around 10,000 mature individuals.
Habitat
A large emergent tree mainly restricted to areas of lowland rainforest that are mostly on non-ultramafic substrates.
Threats
Substantial, but unquantified, declines have occurred in recent years due to overexploitation of the timber. An increase in fires and conversion of forest to other uses has led to increased habitat fragmentation and a lack of regeneration in some places. It is moreover impacted by invasive species as juvenile plants seem to be eaten by Rusa deer.
Conservation
This species is protected in province Nord but not in province Sud. Very few subpopulations are within protected areas (Mont Panié, Forêt Nord, Aoupinié).
