Zanthoxylum nadeaudii

Declining

Overview

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

Zanthoxylum nadeaudii faces severe pressure from habitat destruction as French Polynesian forests are cleared for development and agriculture. The species' extremely limited range makes it particularly vulnerable to invasive plant species that outcompete native vegetation and alter forest composition. Climate change poses an additional threat through altered precipitation patterns and increased storm intensity affecting the fragile island ecosystems where this endemic tree survives.

Threat summary

Habitat

This endemic tree species inhabits the remaining native forests of French Polynesia, typically found in montane and coastal forest ecosystems. It grows in areas with well-drained soils and benefits from the humid tropical climate characteristic of Pacific island environments.
