BCT have issued updated Covid-19 advice which means waterways surveys can be undertaken this year, with some limitations. The summary for Somerset is on our website, with the full updated advice on the BCT website.
This survey monitors the activity of Daubenton’s bats along a waterway.
The survey method is straightforward and is ideal to try if you are relatively new to bat detecting. You will need a heterodyne (tuneable) bat detector and a torch (contact the Bat group) if you need to borrow a detector for a survey).
The waterways survey is over 2 nights, the first survey should be first two weeks of August and the second survey during the third and forth weeks. The survey begins 40 minutes after sunset and usually takes about one hour.
