Sorbus leyana
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sorbus leyana faces severe threats from habitat degradation and extremely limited distribution, being restricted to a handful of locations in the Welsh mountains. The species is vulnerable to grazing pressure from livestock and deer, which prevents natural regeneration and damages existing trees. Climate change poses an additional long-term threat, as warming temperatures may force this montane species to higher elevations where suitable habitat becomes increasingly scarce.
Habitat
Sorbus leyana inhabits rocky mountain slopes, cliff ledges, and steep ravines in the Welsh uplands, typically growing on base-rich soils in areas with some protection from grazing. The species favors montane environments with good drainage and partial shelter from harsh weather conditions.
