Alnus henryi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Alnus henryi faces severe population decline due to extensive deforestation and habitat conversion throughout its native range in southwestern China. The species is particularly vulnerable to logging operations and agricultural expansion in montane regions, while climate change threatens to shift suitable habitat zones beyond the tree's adaptive capacity. Small, fragmented populations are increasingly isolated, reducing genetic diversity and limiting natural regeneration potential.
Habitat
Alnus henryi inhabits montane forests and riparian zones in southwestern China, typically growing along streams and in moist valley bottoms at elevations between 1,500-3,000 meters. The species prefers well-drained soils in mixed deciduous forests and forest margins within temperate mountain ecosystems.
