Overview

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

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.
