Aristolochia delavayi

Unknown

Overview

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

Aristolochia delavayi faces severe pressure from habitat destruction as its montane forest ecosystems are cleared for agriculture and urban development across its limited range in southwestern China. The species' specialized pollination requirements and narrow ecological niche make it particularly vulnerable to fragmentation, while overcollection for traditional medicine compounds population declines in remaining forest patches.
