Lejeunea drehwaldii

Unknown

Overview

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

Lejeunea drehwaldii faces severe threats from deforestation and habitat degradation in its extremely limited range. The species' dependence on specific microhabitat conditions within tropical forests makes it particularly vulnerable to logging activities and agricultural conversion. Climate change poses an additional threat through altered precipitation patterns and temperature regimes that could disrupt the delicate moisture balance required for this bryophyte's survival.

Threat summary

Habitat

This critically endangered liverwort inhabits the bark of trees and decaying logs in humid tropical forests, requiring specific moisture and light conditions. It typically occurs in undisturbed primary forest environments where stable microclimatic conditions support its growth on various substrates including tree trunks and fallen woody debris.
