Overview

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

Stellate Orthotrichum Moss faces severe threats from habitat degradation and loss of suitable substrate trees due to deforestation, urbanization, and changes in forest management practices. Air pollution and climate change further compromise this epiphytic species by altering the chemical composition of bark substrates and disrupting the humid microclimate conditions essential for its survival.

Threat summary

Habitat

This epiphytic moss grows on the bark of deciduous trees, particularly in humid woodland environments and along stream corridors. It typically occurs in areas with consistent moisture levels and clean air conditions, often favoring older trees with suitable bark texture and chemistry.
