We have now done all three roost visits planned for the tunnel and the results have been written up and passed to Elspeth Ingelby at NYMNP. We found both Myotis and Common pipistrelle bats using the tunnel on the main three visits and a final check of the tunnel found a Brown long-eared bat roosting on the ceiling. The data from the spring/summer visits seems to ask as many questions as it answers and there are indications that the bats may even be using the tunnel as a ‘route through’. Certainly there is no ‘major’ roost present but it is being well used. The winter hibernation visits did not add anything to the single record we have from 2016 of a single bat hibernating there. We will wait and see what proposals come forward for the future of the tunnel but thanks to the help of all the volunteers we now at least have a much better knowledge of its use by bats. Thanks to everyone involved.
