Tumid Notchwort

Lophozia ventricosa

UnknownLCEULCEU

Overview

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

The Tumid Notchwort faces significant pressure from habitat degradation caused by atmospheric nitrogen deposition, which alters the chemical composition of its specialized bryophyte communities. Climate change poses an additional threat through increased temperatures and altered precipitation patterns that disrupt the cool, moist conditions essential for this liverwort's survival. Agricultural intensification and urban development continue to fragment and destroy the species' remaining suitable habitats.

Threat summary

Habitat

The Tumid Notchwort inhabits acidic, nutrient-poor soils in heathlands, moorlands, and open woodlands, typically growing among other bryophytes in areas with consistent moisture. It favors disturbed ground such as peat cuttings, track sides, and areas with thin soil cover over rock or sand.
