Sorbus haesitans
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sorbus haesitans faces severe population decline due to habitat fragmentation and degradation of its specialized montane woodland environments. The species is particularly vulnerable to grazing pressure from livestock and deer, which prevents natural regeneration of saplings. Climate change poses an additional threat by altering the temperature and moisture conditions of its high-altitude habitats, potentially forcing populations to migrate to increasingly limited suitable areas.
Habitat
Sorbus haesitans inhabits montane woodlands and rocky slopes at elevations typically between 300-800 meters, favoring well-drained soils and partially shaded conditions. The species is often found growing among other native trees and shrubs in fragmented woodland patches, particularly on steep terrain that provides some protection from intensive land use.
