We can all help monitor the long term trends in bat populations, by either helping at an existing roost emergence count, or by adding a new one.

Most roosts are counted in June. Lesser horseshoe bat counts start in late May, while greater horseshoe bat counts take place into July.
Helping at an existing Roost count
Some roosts may be small with just one exit and hence require just one or two people, however others are vast with many exits, and different species, and might need a dozen or more folks all with eyes glued and clicker counters in hand. Hence there are lots of chances to get involved, and no experience is needed as full guidance will be given by the designated roost surveyor.
If you would like to help, then watch out for the requests for help on our Facebook page nearer the time when the lead surveyor has agreed dates with the landowner.
Counting a new Roost
If you have some experience identifying bats and know of a bat roost near you, or have bats roosting on your property, then you can help Bat conservation by counting bats emerging from the roost on two or more evenings during June.
The group has a stock of Bat detectors, and can help with loan of equipment if required.
Taking on a Dormant Roost
There are several roosts that were surveyed in the past, but for various reasons have not been done for several years. There can be many reasons, from the surveyor moving away, or simply that the bats moved on. However after some time it could be worthwhile reassessing these roosts.
If you would like to help, let us know, and we’ll see if we know of a dormant site in your area.
