Bat echolocation data is collected using automated bat detectors (sometimes referred to as static detectors), and can often result in thousands of files being recorded. This can be time consuming for busy ecologists to work through and identify the echolocation sound to the different bat species. This requires a level of expertise and sufficient training to accurately undertake the analysis, particularly where tricky species may be present.
Whilst auto identification tools are becoming more common place, many experienced analysts will agree that there is a long way to go before these methods can be relied upon for accurate results. Therefore, Prime Environment uses a hybrid system which organises calls into groups of similar traits, but all files are manually examined to identify each bat call individually.
Outputs can be tailored to our clients’ needs, whether this is a simple table with time and bat species, or a more substantial output with graphs and written interpretation. Our most common deliverable is a standalone bat report with methods and results which can be slotted in as an appendix in an EcIA report.
We can cover most data sources including the suite of AnaBat (SD1, SD2, Express) and Wildlife Acoustics (SM2, EchoMeter Touch) recording devices, and will be able to find a solution for your preferred equipment.
