Overview

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

Streamside Hygroamblystegium Moss faces severe threats from habitat degradation due to water pollution, altered hydrology from dam construction and water diversions, and climate change impacts on freshwater systems. The species' dependence on specific moisture and water quality conditions in riparian environments makes it extremely vulnerable to human activities that modify natural waterways and their immediate surroundings.
