Callitris neocaledonica Dümmer

Restricted to the higher elevations of New Caledonia. The major threat is wildfire; some subpopulations have been effected by trail construction to facilitate tourism.


This species is restricted to the higher parts of the southern massif on New Caledonia at 950-1350 m

The total population is estimated to be more than 10,000 individuals in several locations. This species is slow growing and there is little regeneration in most subpopulations.

Habitat and Ecology

Mainly limited to higher altitude maquis the higher ridges and plateaus of the southern ultramafic massif. Mean annual precipitation is above 2300 mm amd mean anual temperature is 18.3°C (Larter et al., 2017). Cones are not serotinous - this species is susceptible to fire and droughts associated with El Niño events (Ladd et al., 2013).

Human Uses

The timber of this species has been used in the past. Essential oils from this species and C sulcata have shown to have antifungal properties (Waikedre et al., 2012).

Conservation Status

Global Status

Near Threatened

Global Rationale

This species has a restricted distribution with an estimated extent of occurrence of only 257 kmand there is continuing decline in the extent and quality of the habitat. However, as the species is not severely fragmented and it is known from more than ten locations, it is listed as Near Threatened: it almost qualifies for a threatened listing under criterion B1ab(iii).

Global threats

The major threat is wildfire; some subpopulations have been effected by trail construction to facilitate tourism.

Conservation Actions

Most subpopulations are protected in Montagne des Sources and Mt. Humboldt Botanical Reserve
