Diplazium subquadripinnatum

Unknown

Overview

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

Diplazium subquadripinnatum faces severe pressure from deforestation and habitat conversion in its limited montane forest range. Agricultural expansion and logging activities have fragmented the remaining populations, while climate change threatens to shift suitable habitat zones beyond the species' adaptive capacity. The fern's specialized requirements for humid, shaded understory conditions make it particularly vulnerable to forest degradation and edge effects.

Threat summary

Habitat

This endangered fern inhabits humid montane forests, typically growing in shaded understory conditions on forest floors and rocky slopes. It requires consistent moisture levels and protection from direct sunlight, making it dependent on intact forest canopy cover.
