In the humid region of the northeastern mountains in Phong Nha-Ke Bang National Park, Quang Binh province, Aristolochia quangbinhensis grows as a single population underneath the primary, broad-leaved, evergreen forest. Anthropogenic threats, such as excessive logging, have resulted in the vulnerability of this new flora species and put it in an endangered status.^[5]
