Sorbus adeana
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sorbus adeana faces severe population decline due to its extremely restricted range in the Arran whitebeams complex of Scotland. The species is threatened by habitat degradation from grazing pressure, particularly by deer and sheep, which prevents natural regeneration. Climate change poses additional risks to this cold-adapted montane species, while its small population size makes it vulnerable to genetic bottlenecks and stochastic events.
Habitat
Sorbus adeana is endemic to rocky slopes and cliff ledges in the montane regions of the Isle of Arran, Scotland. It typically grows on inaccessible granite outcrops and scree slopes at elevations between 300-600 meters, where it can escape grazing pressure.
