Drones in ecology: ten years back and forth.

A decade after our initial publication predicting that lightweight drones would revolutionize spatial ecology, drone technology has become firmly established in ecological studies. In the present article, we explore the key developments in ecological drone science since 2013, considering plant and animal ecology, imaging and nonimaging workflows, advances in data processing and operational ethics. Focusing on inexpensive, lightweight drones equipped with various sensors, we offer a critical evaluation of drone futures for ecologists, arguing that this could deliver opportunities for volumetric ecology to take flight. We discuss the potential future uses of drones in aerobiology and in understory and underground ecological studies and debate the future of multirobot cooperation from an ecological standpoint. We call on ecologists to engage critically with drone technology in this next phase of development.
