02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

The Purplestem Shoestring Fern faces severe threats from habitat destruction and degradation of its specialized epiphytic environments. Its extremely limited distribution and small population size make it highly vulnerable to environmental changes and human disturbances. The species' dependence on specific microclimate conditions in old-growth forests leaves it particularly susceptible to logging and forest fragmentation.

Key Facts

03Habitat

Habitat & Distribution

This epiphytic fern grows exclusively on tree trunks and branches in humid, old-growth tropical forests, typically in areas with consistent moisture and filtered light conditions. It requires specific microclimate conditions found in undisturbed forest canopies and understory environments.
