Sorbus ratisbonensis

StableENEUENEU

Overview

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

Sorbus ratisbonensis faces severe population pressure from habitat fragmentation and urban development in its limited Bavarian range. The species' extremely restricted distribution makes it vulnerable to localized disturbances, while hybridization with related Sorbus species threatens genetic integrity. Climate change poses additional risks by altering the specific microhabitat conditions this endemic rowan requires for survival.

Threat summary

Habitat

This endemic rowan occupies rocky slopes, limestone cliffs, and open woodland edges in the Bavarian region of Germany. It typically grows in calcareous soils at moderate elevations, often in areas with partial shade and good drainage.

Frequently asked questions

Why is Sorbus ratisbonensis classified as Endangered?
Sorbus ratisbonensis 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 ratisbonensis faces severe population pressure from habitat fragmentation and urban development in its limited Bavarian range. The species' extremely restricted distribution makes it vulnerable to localized disturbances, while hybridization with related Sorbus species threatens genetic integrity. Climate change poses additional risks by altering the specific microhabitat conditions this endemic rowan requires for survival.
Where does Sorbus ratisbonensis live?
Sorbus ratisbonensis 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 ratisbonensis?
The main threats to Sorbus ratisbonensis 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.
