Overview

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

Aristolochia tuberosa faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its native range in southeastern United States. The species is particularly vulnerable to collection pressure for medicinal use, as traditional herbalists value its tuberous roots. Climate change poses an additional threat through altered precipitation patterns that affect the moist woodland conditions this species requires for successful reproduction.

Threat summary
