Recent years have seen a rapid rise in the use of technological equipment within the field of ecology. From high-tech drones, to the humble bat detector, ecologists are increasingly using technology to aid with data collection during surveys.

Most technology used in ecological surveys relies on sensing physical aspects of the environment. Sensors convert physical magnitudes such as heat, sound, and motion into interpretable electric signals (Figure 1). Analysis of these signals can have various applications, including detecting animals during darkness/low visibility, mapping vegetation and landscape features, detecting rare/elusive species, and understanding animals’ behaviour.  At E3, we use a wide suite of technology to aid with data collection; infrared and thermal cameras for bird surveys and bat emergence and transect surveys, drones for habitat mapping, Anabats for recording bat calls, and camera traps for detecting elusive protected species such as the European otter. Some examples of surveys where we have successfully used such technology are provided below.
