NBMP Roost Emergence Counts in June

We can all help monitor the populations of bats, by either helping at an existing roost emergence count, or for the more experienced, by taking on a dormant roost or 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 in 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, you can either;

If you are an existing roost surveyor, and would like some help with counting you roost, let us know, and we’ll add your (anonymised) site to the list.

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, then please review the list of dormant emergence roost sites, then contact the original surveyor who can give you the background.

If you know of any other dormant roost surveys, let us know, and we’ll add your (anonymised) site to the list.
