A drone has discovered a rare cliff-dwelling flower that scientists thought was extinct.
Scientists in Kauai, Hawaii used a drone to access the remote area which is largely inaccessible to humans.
According to a report from National Geographic, researchers from the Kaua’i-based National Tropical Botanical Garden (NTBG) previously accessed these cliffs by hiking along treacherous ridgelines and rappelling down vertical cliff faces.
The researchers are now said to be pleased the new drone tool can help them in their work and make it safer.
The drone flight, made in January, discovered the Hibiscadelphus woodii, a relative of hibiscus last seen in 2009, was still growing on the cliffside.
National Geographic went on to describe how the species was first discovered in 1991, named in 1995, and deemed extinct in 2016.
The January drone flight captured one image believed to be H. woodii, tucked into a corner.
In February, they set out on another mission to reconfirm what they saw, flying a drone to the original GPS coordinates and collecting more images, revealing three individual H. woodii plants on the Cliffside.
