Pteris tahuataensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pteris tahuataensis faces severe threats from habitat degradation on its native island of Tahuata in the Marquesas Islands. The species' extremely limited range makes it vulnerable to invasive plant species that compete for resources and alter the native forest understory. Feral ungulates, particularly goats and pigs, trample and destroy the delicate fern populations while degrading the soil structure essential for this species' survival.
Habitat
This endemic fern inhabits the humid montane forests of Tahuata Island in the Marquesas archipelago, typically growing in shaded understory conditions on volcanic soils. It requires the specific microclimate conditions found in these isolated Pacific island forests, including consistent moisture and protection from direct sunlight.
