Nothofagus stylosa

Unknown

Overview

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

Nothofagus stylosa faces severe population decline primarily due to extensive logging and forest clearance for agricultural development across its limited range in New Caledonia. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while invasive plant species compete for resources in disturbed forest areas. Mining activities and urban expansion have further reduced available habitat, with remaining populations increasingly isolated in small forest fragments.

Threat summary

Habitat

This endemic southern beech species inhabits humid montane forests and cloud forests in the mountainous regions of New Caledonia, typically occurring at elevations between 400-1,200 meters. It grows in well-drained soils on slopes and ridges, often forming part of mixed forest communities with other endemic Nothofagus species and native conifers.

Frequently asked questions

Why is Nothofagus stylosa classified as Critically Endangered?
Nothofagus stylosa 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. Nothofagus stylosa faces severe population decline primarily due to extensive logging and forest clearance for agricultural development across its limited range in New Caledonia. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while invasive plant species compete for resources in disturbed forest areas. Mining activities and urban expansion have further reduced available habitat, with remaining populations increasingly isolated in small forest fragments.
Where does Nothofagus stylosa live?
Nothofagus stylosa occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Nothofagus stylosa?
The main threats to Nothofagus stylosa are 5.3, 7.1, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
