Clinosperma macrocarpa

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Clinosperma macrocarpa faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in New Caledonia. Mining activities, particularly nickel extraction, have fragmented and degraded the specialized ultramafic soils this palm requires. The species' extremely restricted distribution makes it highly vulnerable to stochastic events, while invasive plant species compete for resources in its native habitat.

Threat summary

Habitat

This endemic palm inhabits ultramafic soils in the dry forests and shrublands of New Caledonia's southern regions. It typically grows in open woodland areas and forest margins on serpentine substrates, often associated with other endemic flora adapted to these nutrient-poor, metal-rich soils.

Frequently asked questions

Why is Clinosperma macrocarpa classified as Critically Endangered?
Clinosperma macrocarpa 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. Clinosperma macrocarpa faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in New Caledonia. Mining activities, particularly nickel extraction, have fragmented and degraded the specialized ultramafic soils this palm requires. The species' extremely restricted distribution makes it highly vulnerable to stochastic events, while invasive plant species compete for resources in its native habitat.
Where does Clinosperma macrocarpa live?
Clinosperma macrocarpa 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 Clinosperma macrocarpa?
The main threats to Clinosperma macrocarpa are 5.4, 8.1, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
