Araucaria nemorosa

Declining

Overview

Araucaria nemorosa is a species of conifer in the family Araucariaceae. It is found only in New Caledonia, an island possession of France in the South Pacific. It is mostly found as a small understory tree, typically growing to no more than 15 meters, and relatively shade tolerant, though it can also grow as an emergent from coastal scrub.

It has feathery foliage somewhat less spiky than most other Araucaria species, and is found only on serpentine soil, in coastal locations below 100m in altitude. It is threatened by habitat loss and is a critically endangered species with less than 5000 trees remaining in the wild. Low levels of genetic variation in the remaining population and consequent low germination rates of seed produced, are also a concern.

Araucaria nemorosa faces severe population decline primarily due to extensive logging and forest clearance for agricultural expansion across its limited range in New Caledonia. Mining activities, particularly nickel extraction, have destroyed significant portions of its native forest habitat. The species' extremely restricted distribution makes it highly vulnerable to localized threats, with remaining populations fragmented and isolated.

Threat summary

Habitat

This endemic conifer occurs in humid montane forests of New Caledonia, typically growing on ultramafic soils at elevations between 400-1,200 meters. It inhabits dense rainforest canopies alongside other endemic Araucaria species in one of the world's most botanically unique ecosystems.

Frequently asked questions

Why is Araucaria nemorosa classified as Critically Endangered?
Araucaria nemorosa is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Araucaria nemorosa faces severe population decline primarily due to extensive logging and forest clearance for agricultural expansion across its limited range in New Caledonia. Mining activities, particularly nickel extraction, have destroyed significant portions of its native forest habitat. The species' extremely restricted distribution makes it highly vulnerable to localized threats, with remaining populations fragmented and isolated.
Where does Araucaria nemorosa live?
Araucaria nemorosa occurs in New Caledonia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Araucaria nemorosa?
The main threats to Araucaria nemorosa are 12.1, 3.2, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
