Species Profile
Odontoschisma sphagni, commonly known as bog-moss flapwort, is a species of liverwort in the family Cephaloziaceae. It grows in raised bogs on moist, peaty soil, on rotten and dead wood or on thin soil covering moist sandstone rock in evergreen or deciduous forests. It sometimes grows among mosses.
Bog-moss Flapwort faces significant threats from habitat degradation and loss of specialized bog ecosystems. Climate change and human disturbance to peatlands are reducing the availability of suitable acidic, waterlogged conditions this species requires for survival.
Key Facts
Habitat & Distribution
Acidic bogs, peatlands, and wet heathlands with Sphagnum moss communities, typically in nutrient-poor, waterlogged conditions. Often found growing directly on or among Sphagnum moss in oligotrophic wetland environments.
Threats
Climate change affecting bog hydrology
Peatland drainage and destruction
Atmospheric pollution and nitrogen deposition
Changes in water chemistry
Habitat fragmentation
