Image: Imperial College London - A team of researchers from Empa and Imperial College London developed drones that can attach sensors to trees to monitor environmental and ecological changes in forests. Sensors for forest monitoring are already used to track changes in temperature, humidity and light, as well as the movements of animals and insects through their habitats. They also help to detect and monitor forest fires and can provide valuable data on how climate change and other human activities are affecting the natural world. Placing these sensors can, however, prove difficult in large, tall forests, and climbing trees to place them poses its own risks. Now, a team of researchers from Empa and Imperial College London has developed drones that can shoot sensor-containing darts onto trees several meters away in cluttered environments like forests. The drones can also place sensors through contact or by perching on tree branches.
