Overview

Distribution

Range Description

Confined to a few localities in the south of Grand Terre, with a single very small subpopulation on the summit of Mt Paéoua, 180 km to the north. No subpopulations have been recorded from the intervening area. Recorded from 30 to 1,140 m asl.

Justification
There has been an estimated population size reduction of more than 50% over the last three generations resulting in a decline in the area of occupancy and quality of habitat. This is based on levels of past exploitation, the extent of inundation in the 1960s and a comparison of historic and recent herbarium records. The current extent of occurrence (EOO) is estimated to be 1,597 km2. The current area of occupancy is estimated to be 32 km2 with only three locations (Paéoua, Montagne des Sources, Plaine des Lacs/Chute de Madelaine). The main subpopulations are severely fragmented in terms of their geographic and ecological isolation. A continuing decline in the area of occupancy and quality of habitat is also projected due to the increasing frequency of fires and the effects of mining. There would be a very significant reduction in the extent of occurrence if the subpopulation at Paéoua were to be eliminated (without it, the EOO would be about 200 km2). On this basis, an assessment of Endangered under criteria A2cd and B1ab(ii,iii,v)+2ab(ii,iii,v) is reasonable.

Population

Population
The total population is estimated to be between 2,500 and 10,000. Subpopulations range in size from a few to several hundred individuals (Plateau des Callitropsis). At Mont Paéoua only 45 mature trees have been found.

Threats

Major Threats
Increasing fire frequency is currently the main threat throughout its range. The subpopulation on Mt. Paéoua is also threatened by mining activities. In the past this species was exploited for its resin and wood. Several subpopulations were also inundated by reservoirs behind the Yaté dam in the 1960s.

Conservation Actions

Conservation Actions
Several of the southern subpopulations occur in protected areas although these are still vulnerable to repeated burning. Restoration work has been initiated at the Chute de Madelaine reserve.

Neocallitropsis

Neocallitropsis pancheri is a plant species of the family Cupressaceae and the sole species of the genus Neocallitropsis. It is endemic to New Caledonia, where it occurs in small, scattered population along rivers.[1]

It is an evergreen coniferous tree growing to 2–10 metres (7–33 ft) tall. The leaves are awl-shaped, 1 centimetre (0.4 in) long, arranged in eight rows in alternating whorls of four; in overall appearance, the foliage is superficially similar to some species of Araucaria, though they are only very distantly related. Neocallitropsis is dioecious, with separate male and female trees; the seed cones are 1.5–2.0 cm (0.6–0.8 in) long, with eight woody scales arranged in two whorls of four.
