Canacomyrica monticola is known to occur in eleven localities in the south of Grande Terre, New Caledonia where it grows exclusively on ultramafic substrates. Of these localities, six are afforded no official protection and disturbance has been observed at the Mont Mamié site. There is evidence of disturbance caused by mining prospection at the Ouinné site and the Nembrou site is potentially threatened by bush fire (J. Manaute and T. Jaffré pers. comms.). C. monticola is estimated to have an EOO of 1,500 km². Within this area its distribution is severely fragmented. If the population at Mt Bouo where C. monticola occurs in an area of approximately 100 m² is typical, then it would suggest that local distribution is very limited. Whilst it is inappropriate to make an estimate of total area of occupancy (AOO) based on one observation alone, it is possible to state that AOO is significantly less than EOO. Continuing decline is projected in EOO, AOO and number of locations. Continuing decline in number of mature individuals is inferred at the Mont Mamié, Ouinné and Nembrou sites. It is therefore recommended that C. monticola be listed as Endangered (EN B1ab(i,ii,iv,v)).

Habitat and Ecology [top]

Habitat and Ecology:Limited to ultramafic (or serpentine) geology which covers an area of 5,500 km². Occurs in primary moist forest at high altitudes (mostly above 800 m) and wet scrub at lower altitudes (500–800 m). Probably wind pollinated, fruits may be animal dispersed, low seed fertility observed.

Threats [top]

Major Threat(s): Mining - two localities known to be affected, all unprotected localities vulnerable due to the geology.
Bush fire - one locality known to be threatened, others are likely to be threatened by fire.
Logging - possible threat in unprotected sites.

Conservation Actions [top]

Conservation Actions: Five localities are currently protected (Strict Nature Reserve of Montagne des Sources, Special Fauna and Flora Reserve of Mt Kouakoué, Specila Botanical Reserve of Mt Humboldt and Special Fauna and Flora Reserve of Forêt de Saille).
