Drones are increasingly used to gather information and inform research. As technology develops longer-lasting batteries and more sensitive cameras, the role of drones in research will continue to grow. (Shutterstock)

Drones help track wildfires, count wildlife and map plants

Drones have proven extremely useful for research, collecting detailed data to help monitor hard-to-access areas.
