Hymenophyllum hirtellum

Unknown

Overview

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

Hymenophyllum hirtellum faces severe threats from habitat destruction due to deforestation and agricultural expansion in its limited range. The species' dependence on specific microclimate conditions within humid forest environments makes it extremely vulnerable to even minor habitat modifications. Climate change poses an additional threat by altering the moisture regimes essential for this delicate fern's survival.

Threat summary

Habitat

This filmy fern inhabits humid, shaded forest environments where it grows as an epiphyte on tree trunks and rocks in areas with consistently high moisture levels. It requires very specific microclimate conditions with stable humidity and filtered light typical of undisturbed tropical or subtropical forests.
