Unmanned aerial vehicles (UAVs), often referred to as drones, offer a far cheaper and safer alternative to using planes or helicopters for the aerial surveying of salmon redds (spawning nests) in large rivers. Our research will use UAVs to locate redds in small creeks, which are traditionally surveyed on foot or not at all. UAV technology will allow for much broader-reaching surveys of small creeks and will give salmon researchers a more complete picture of salmon spawning habits.
