A mini helicopter has been used by researchers from Worcester to examine the threat to rare fish species posed by a dam on a Chilean river.
The work was carried out by PhD student Amy Woodget and Dr Ian Maddock, principal lecturer in physical geography at the University of Worcester. (...)
Professor Habit Evelyn Habit, from the University of Concepcion, said the images from the Draganflyer UAS showed the river in "an extraordinarily high level of detail".
"This allows us to better understand the habitat availability for our native fish species," he said.
