Overview

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

Streamside bryum moss faces significant pressure from habitat degradation along waterways, particularly through agricultural runoff, urban development, and water management practices that alter natural flow regimes. The species' specialized requirement for stable, moist substrates near flowing water makes it highly vulnerable to hydrological changes and pollution. Climate change compounds these threats by altering precipitation patterns and increasing the frequency of extreme weather events that can scour away moss colonies.

Threat summary

Habitat

Streamside bryum moss grows on wet rocks, soil, and organic matter along the margins of streams, rivers, and other flowing water bodies. It requires consistently moist conditions and typically establishes on stable substrates within the spray zone of moving water.
