Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Streamside Schistidium Moss faces severe threats from habitat degradation due to water pollution, altered hydrology from dam construction and water diversions, and climate change impacts on streamflow patterns. Its specialized requirement for clean, fast-flowing water makes it particularly vulnerable to human activities that modify aquatic ecosystems and water quality.
Key Facts
Habitat & Distribution
Rocky substrates in and alongside fast-flowing, clean mountain streams and rivers, typically in cool, humid environments. The species requires consistent moisture from spray and splash zones of flowing water systems.
Threats
IUCN Red List: Critically Endangered
