Species Profile
Campylium protensum is a species of moss belonging to the family Amblystegiaceae.
Dull starry fen moss (Campylium protensum) is critically endangered primarily due to habitat loss and degradation of its specialized wetland environments. The species requires specific hydrological conditions in calcareous fens and wet meadows, which are increasingly threatened by drainage, agricultural intensification, and water table changes. Climate change and pollution further compound these pressures on the remaining fragmented populations.

The species requires specific hydrological conditions in calcareous fens and wet meadows, which are increasingly threatened by drainage, agricultural intensification, and water table changes. Climate change and pollution further compound these pressures on the remaining fragmented populations.
Agricultural intensification and land use change
Eutrophication from nutrient pollution
Habitat drainage and water table lowering
Climate change altering hydrological regimes
Habitat fragmentation and small population size
