A drone surveying a cliff face in a remote part of Kalalau Valley in
Hawaii’s Kaua‘i Island has confirmed the presence of *Hibiscadelphus woodii*,
a relative of hibiscus that was last seen alive in 2009, and thought to be
extinct. Biologists first spotted four *H. woodii* plants in March 1991,
but three of the plants were crushed and killed by falling boulders between
1995 and 1998. The remaining known individual was last observed alive in
2009, and then seen dead in 2011. However, by flying into
difficult-to-reach areas, drones are uncovering secrets of previously
unexplored cliff habitats.
