Overview

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

The Northern Naugehyde Liverwort faces severe decline due to habitat degradation from atmospheric pollution, particularly nitrogen deposition and acid rain, which alter the delicate chemical balance of its substrate. Climate change poses an additional threat through increased temperatures and altered precipitation patterns that affect the moisture-dependent reproductive cycles essential for spore production and establishment.

Threat summary

Habitat

This liverwort inhabits acidic, nutrient-poor substrates including rotting logs, peat soils, and rock crevices in boreal and montane forests. It requires consistently moist conditions and is typically found in shaded microsites with stable humidity levels.
