Overview

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

Sorbus schuwerkiorum faces severe threats from its extremely restricted range and small population size, making it highly vulnerable to stochastic events. The species is threatened by habitat degradation from grazing pressure and potential climate change impacts on its montane environment. Human activities in the surrounding landscape, including infrastructure development and agricultural expansion, pose additional risks to the remaining habitat fragments.

Threat summary

Habitat

This critically endangered rowan species is endemic to montane regions, typically found in rocky slopes and cliff areas at high elevations. It occupies specialized microhabitats within mountainous terrain, often growing in crevices and on steep rocky outcrops where it can persist despite harsh environmental conditions.
