Sorbus harziana
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sorbus harziana faces severe population decline due to its extremely restricted range in the Harz Mountains of Germany, where it exists as only a few isolated individuals. The species is threatened by habitat degradation from forestry practices, recreational pressure, and climate change effects on montane ecosystems. Hybridization with more common Sorbus species poses an additional genetic threat to the remaining pure populations.
Habitat
Sorbus harziana occupies rocky slopes and forest edges in the montane regions of the Harz Mountains, typically growing on calcareous soils at elevations between 400-800 meters. The species favors semi-open woodland margins and rocky outcrops where it can access sufficient light while benefiting from some forest protection.
