Overview

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

Jagged Germanderwort faces severe pressure from habitat degradation in its specialized montane environments, where logging and agricultural expansion have fragmented its limited range. Climate change poses an additional threat as warming temperatures push suitable conditions to higher elevations, potentially eliminating habitat for this elevation-restricted species. The bryophyte's dependence on specific moisture and substrate conditions makes it particularly vulnerable to environmental changes that alter forest microclimates.

Threat summary

Habitat

This liverwort species inhabits moist, shaded environments in montane forests, typically growing on decaying wood, soil, and rock surfaces in areas with consistent humidity. It requires specific microhabitat conditions found in undisturbed forest ecosystems at higher elevations.
