What is the current state of health of our trees and forests? Is a tree under stress? Is it lacking nutrients? Where does it get its water from? To answer these questions, branch and leaf samples from the tree canopy are often required. But how do you obtain these from trees that are up to 40 metres tall? Malkin Gerchow and Sfeffen Dohmen from the Isodrones research group and tree-climbing researchers at the University of Göttingen launched a ‘research duel in the canopy’: a competition between a tree climber and a sampling drone.
