Sorbus avonensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sorbus avonensis faces severe threats from habitat degradation and extremely limited population size, with only a handful of mature individuals known to exist in the wild. The species is vulnerable to genetic bottlenecks due to its tiny population, while ongoing pressures from grazing, invasive species, and potential climate-driven habitat shifts threaten the remaining trees. Collection pressure from botanical enthusiasts and the species' inability to reproduce effectively in such small numbers further compound its precarious status.
Habitat
Sorbus avonensis occurs in rocky limestone gorges and cliff faces along river valleys in southwestern England. The species typically grows in calcareous soils on steep slopes and rocky outcrops where it can access adequate moisture while avoiding competition from larger trees.
