Overview

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

The twotoothed cephalozia faces significant pressure from habitat degradation in its specialized wetland environments. Climate change poses a particular threat through altered precipitation patterns and temperature increases that can dry out the moist, acidic substrates this bryophyte requires. Agricultural intensification and drainage of peatlands and bog margins have reduced suitable habitat across much of its range, while atmospheric pollution continues to alter the delicate chemical balance of its preferred growing conditions.

Threat summary

Habitat

This small leafy liverwort inhabits acidic, nutrient-poor environments including sphagnum bogs, wet heathlands, and the margins of oligotrophic pools. It typically grows on decaying organic matter, peat, and occasionally on rotting wood in consistently moist, shaded microsites within these specialized wetland ecosystems.
