Byssoloma permutans

Unknown

Overview

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

Byssoloma permutans faces severe threats from deforestation and habitat fragmentation in its limited range within tropical montane cloud forests. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and human disturbance. Climate change poses an additional threat by altering the specific humidity and temperature conditions required for this lichen's survival.

Threat summary

Habitat

Byssoloma permutans is endemic to tropical montane cloud forests, typically growing on tree bark and branches in areas with high humidity and consistent moisture levels. The species requires the specific microclimate conditions found in these elevated forest ecosystems, particularly the persistent fog and mist that characterize cloud forest environments.
