The global decline of plant species exerts a significant detrimental impact on the stability of natural ecosystems. Endemic species with restricted geographical distributions are at risk of extinction in their natural habitats. Consequently, the investigation of rare plant species, the analysis of their current status, and the development of conservation measures are of substantial scientific and practical significance. Astragalus knorringianus Boriss. represents one such critical plant species.
