Sorbus hohenesteri
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sorbus hohenesteri faces severe population decline due to its extremely restricted range in the Austrian Alps, where it exists in only a few isolated locations. The species is threatened by habitat degradation from tourism infrastructure development, grazing pressure from livestock, and climate change impacts that alter the specific montane conditions it requires. Competition from invasive plant species and genetic bottlenecks due to small population size further compound its vulnerability.
Habitat
This endemic rowan species inhabits rocky slopes, scree, and cliff faces in montane and subalpine zones of the Austrian Alps, typically growing at elevations between 1,200-2,000 meters. It requires well-drained, calcareous soils and thrives in the specific microclimate conditions found in alpine limestone environments.
