StableCREUCREU

Overview

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

Sorbus mergenthaleriana faces severe population decline due to its extremely restricted range and small population size. The species is threatened by habitat degradation from agricultural expansion and livestock grazing in its montane forest habitat. Climate change poses an additional threat as warming temperatures may shift suitable habitat zones beyond the species' limited dispersal capabilities.
