Species conservation profile and amended distribution of Cousinia knorringiae (Asteraceae), a narrow endemic of the Western Tian-Shan

A new population of Cousinia knorringiae, an endangered plant endemic to the Western Tian-Shan, has been discovered in eastern Uzbekistan, expanding its known distribution beyond Kyrgyzstan. This species, characterized by its narrow range and small population (200-250 mature individuals), is now recognized as part of the East Fergana botanical hotspot—a transborder region shared by Kyrgyzstan and Uzbekistan—highlighting the need for international conservation efforts. The study clarifies its type locality, provides an updated distribution map, and assesses its conservation status as Endangered (EN) under IUCN criteria. Additionally, Ungur-Tepa Mt., where the species was found, is identified as a critical area for plant biodiversity in Uzbekistan, warranting legal protection.
