Cyathea retanae

Unknown

Overview

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

Cyathea retanae faces severe threats from deforestation and habitat conversion in its limited range within the Philippines. The species is particularly vulnerable due to its restricted distribution and dependence on intact forest ecosystems. Agricultural expansion and logging activities have significantly reduced suitable habitat, while the species' slow growth rate and specific microclimate requirements make recovery extremely challenging.

Threat summary

Habitat

This tree fern inhabits montane forests in the Philippines, typically growing in humid, shaded understory environments with consistent moisture levels.
