Macromitrium attenuatum
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Macromitrium attenuatum faces significant pressure from deforestation and habitat degradation across its limited range in tropical montane forests. The species' epiphytic lifestyle makes it particularly vulnerable to logging activities and forest fragmentation, which alter the microclimate conditions essential for moss survival. Climate change poses an additional threat through shifting precipitation patterns and temperature increases that could push this montane specialist beyond its ecological tolerance limits.
Habitat
This epiphytic moss species inhabits the bark of trees in tropical montane cloud forests, typically at elevations between 1,000-2,500 meters. It requires the consistently humid microclimate provided by intact forest canopies and is particularly associated with older growth trees that provide stable substrate conditions.
