Bat Groups involved include Kent Bat Group, Surrey Bat Group, South Lancashire Bat Group, Northumbria Bat Group and a joint venture by Derbyshire and Nottinghamshire Bat Groups.
The survey is following a set methodology using 2 x harp traps and acoustic lures at 4 sites per county with (ideally) a survey at each of the main sites once a month through the summer. Any Nathusius’ pipistrelles caught are to be processed in a set way including taking fur clippings and attaching a forearm ring. The fur clip is to be sent for stable isotope analysis to see if that method can shed light on if the bat is a migrant or if it is part of a resident population. We will also be fur sampling a selection of common or soprano pips caught.
As its a joint venture by our groups that means we will have 2 main sites each but will be looking at trying to trap at other sites as time allows.
Each group have 2 sets of harp traps and acoustic lures plus all the ancillary equipment needed.
BCT want the main sites to be where we have already had at least one positive Nathusius’ record and following last year's survey work our two main study sites are Carsington water and Drakelow nature reserve.
