Sorbus vallerubusensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sorbus vallerubusensis faces severe threats from its extremely restricted range and small population size, making it vulnerable to stochastic events and genetic bottlenecks. The species is threatened by habitat degradation from grazing pressure and potential climate change impacts on its specialized montane environment. Human activities in the surrounding landscape, including recreational use and infrastructure development, pose additional risks to the remaining populations.
Habitat
This endemic rowan species occupies rocky slopes and cliff ledges in montane environments, typically growing in calcareous soils at elevations between 300-600 meters. It is restricted to a very small area in the Welsh uplands, where it grows in association with other specialized cliff-dwelling plants in areas with limited soil development.
