Nothofagus womersleyi

Declining

Overview

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

Nothofagus womersleyi faces severe population decline primarily due to extensive logging operations targeting its valuable timber in Papua New Guinea's montane forests. Climate change poses an additional threat as rising temperatures force this cold-adapted species to retreat to increasingly limited high-altitude refugia. The species' extremely restricted range, confined to a few mountain peaks above 2,400 meters, makes it particularly vulnerable to both direct exploitation and environmental changes.

Threat summary

Habitat

This endemic southern beech species inhabits upper montane and subalpine forests of Papua New Guinea, typically occurring at elevations between 2,400-3,200 meters. It forms part of the cloud forest ecosystem on isolated mountain peaks, where cool temperatures and high humidity create the specific conditions required for its survival.
