Overview

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

Sorbus parviloba faces severe population decline due to habitat destruction from agricultural expansion and urban development in its limited range. The species is particularly vulnerable to logging activities that target its montane forest habitat, while climate change threatens to shift suitable growing conditions beyond its current elevational range. Small, fragmented populations make the species highly susceptible to genetic bottlenecks and local extinctions from environmental disturbances.

Threat summary

Habitat

Sorbus parviloba inhabits montane deciduous and mixed forests at elevations between 1,200-2,400 meters, typically growing on rocky slopes and forest edges with well-drained soils. The species shows preference for cooler, humid microclimates within its mountainous range, often occurring in association with other temperate forest species.
