vances in UAV technology. ‘I think the UAV of choice [when it comes to biodiversity] will be a rotary machine that can take off vertically and then go straight like a fixed-wing, in other words have folding wings on it. That’s going to be the ideal UAV for wildlife and 29 biodiversity studies in the future. Because you can take off anywhere you want and land anywhere you want within reason. And it will be even better if it has pontoons on it so it can land on the water. There are people working on that right now, but it’s not yet perfected’. The use of UAVs for conservation is becoming an increasingly promising field. As UAV technology continues to expand, so do the possibilities for conservation research. Moving forward, Conservation Drones are hoping to use their UAV to track animals. Serge Wich has highlighted the logistics of such work, commenting that ‘lots of animals from different species have VHF telemetry systems on them, meaning they have a very simple radio on them that emits signals. People usually go on the ground with large antennas to locate these animals by triangulation and it would be much easier if we could fly over these areas and locate them from the air. This is something we are trying to develop with several teams. For instance, orang-utans that we reintroduce get one of these tags and when they move away from the area where we released them they go further than we can walk and we can lose them. We don’t know where they are. Are they alive? Are they dead? Are they near a village? And if we could just fly over these areas and locate them, it would be very useful because every animal has a unique frequency so you could say “Oh Johnny is there”’. David Bird is also eager to see UAVs used for animal tracking, nothing that these machines can ‘be an antenna in the sky and pick up radio signals from animals telling you the animal is nearby. It is something we are hoping to do but we’re not quite there yet. We want to be able to not only pick signals up but send it back down to the ground. It is another holy grail we are working on’. Further down the line, the next challenge for advancing the role that UAVs can play to conservation is achieving automatic object detection. Automatic object detection is software that can automatically identify animals or poachers. This would enable tasks such as counting animals to become completely automated. Whilst still some way off, developing autonomous software for UAVs is a rapidly advancing field and is certainly a key area to watch within conservation research.
