Sorbus adeana

UnknownENEUENEU

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.

Threat summary

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.

Frequently asked questions

Why is Sorbus adeana classified as Endangered?
Sorbus adeana is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. 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.
Where does Sorbus adeana live?
Sorbus adeana occurs in Germany. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Sorbus adeana?
The main threats to Sorbus adeana are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
