Neesioscyphus allionii

Unknown

Overview

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

Neesioscyphus allionii faces severe threats from habitat destruction due to deforestation and agricultural expansion in its limited montane forest range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and human encroachment. Climate change poses an additional threat by altering the specific temperature and humidity conditions required for this bryophyte's survival in high-altitude ecosystems.

Threat summary

Habitat

This critically endangered bryophyte is endemic to specific montane forest environments in the Alps, typically growing on tree bark and rock surfaces in humid, shaded conditions. It requires very specific microclimate conditions found only in undisturbed high-altitude forest ecosystems with consistent moisture levels.
