Pteris nadeaudii

Declining

Overview

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

Pteris nadeaudii faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in the Mascarene Islands. Invasive plant species compete directly with this endemic fern for suitable growing sites, while climate change alters the moisture and temperature conditions essential for its survival. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances and natural disasters.

Threat summary

Habitat

This endemic fern inhabits humid forest understories and rocky crevices in montane regions of the Mascarene Islands. It requires consistently moist conditions and filtered sunlight typical of native forest ecosystems at moderate to high elevations.
