We are frequently asked what is important in a nacelle monitoring of bats at wind turbines. Here questions arise as "What are typical periods for a nacelle monitoring?", "What is outmost acoustical detection range for bats?" or "How do I ensure that the detection system is reliable and records only bat calls and no interference?".

For this reason we decided to write a Guideline for a successful acoustical monitoring of bat activity at wind turbines based on the recently published report of the research project "Reduction of the risk of collision of bats at onshore wind turbines (RENEBAT II)". In this, we explain the key points of nacelle monitoring: the background and the need for such a monitoring, the hardware and software requirements and the evaluation of the recorded bat calls.
