Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
The parchment bristle fern faces severe threats from habitat destruction and fragmentation of its specialized tropical forest environments. Its extremely limited distribution and dependence on specific microclimatic conditions make it highly vulnerable to environmental changes and human disturbance.
Key Facts
Habitat & Distribution
This delicate epiphytic fern inhabits humid tropical rainforests, typically growing on tree trunks and rocks in shaded, moisture-rich environments with consistent high humidity. It requires very specific microclimatic conditions found in undisturbed forest understories and along stream corridors.
