Adit hibernation survey 03/12/2017

By Nicola Faulks, Jan 14 2018 10:15PM

This was our first survey of the 2017-18 season. We checked six adits; all of which are registered with the Bat Conservation Trust’s National Bat Monitoring Programme.


The sites are all lead mine horse levels, narrow tunnels usually lined with stone arching which gives the bats a range of places to roost. Each adit is searched from the entrance inwards by a small team of surveyors led by an experienced and licensed bat worker, minimising the disturbance to any bats found.

Its good fun searching for bats, the tunnels are dirty and wet and the bats can be hard to see, I am sure we are missing more than we find.


The first site we surveyed was our furthest walk in, and hardest to get to at 600m asl, here we recorded five bats, three brown long-eared bats and two Daubenton’s bats. Only one bat was tucked within the arching, the others were hanging openly against the shale section of the adit.



We only found one more bat during the day, tucked deep into the arching in a different adit. This bat was much harder to find….


Moths are the most common species, that we see within the adits, with low counts of Herald moth and a single Tissue moth found. This is a new site record for this moth, which is uncommon in northern Cumbria.
