Jane Sedgeley Project Officer, Our Beacon for Bats 2012 and beyond! By Jane Sedgeley, Project Officer Our Beacon for Bats We began in earnest in May with a Bat Detector Workshop and training day aimed at re-enthusing existing volunteers and recruiting new ones. The VWT’s Conservation Programme Manager and long-time lesser horseshoe bat expert, Dr Henry Schofield, led the day assisted by OB4B Project Officer Jane Sedgeley. The workshop started with indoor presentations on lesser horseshoe bat ecology, a fascinating introduction to bat echolocation from Henry and a session on how to survey for bats using various types of bat Fig.1: Henry Schofield with attendees at our bat detector workshop in detectors. This was followed May 2012 by an outdoor practical session. Despite the chilly weather we successfully recorded a number of bat species along the canal at Talybont-on-Usk and a lesser horseshoe bat on some We also surveyed around adjacent land. 22 km of the Brecon and c Frank Greenaway Monmouthshire canal between To follow on from the bat Llanfrynach and Llangattock. detector day, we ran a series of survey events aimed at Lesser horseshoe bats, along discovering how lesser horseshoe with good numbers of more bats are using the landscape common bat species, such as between two of the largest Daubenton’s bat, common and maternity roost sites the Trust soprano pipistrelles, and manages.

Fig.7: Serotine bat - one of the less common bat species we heard on our bat walk This is an extract of some feedback we received from a participant: “Thank you very much for the Brecon bat walk last night. I thought it was one of the best outdoor family natural history presentations I have attended. The surprise factor was superb. Dreading rain, not enough bat detectors to go round and that [my 14 year old daughter and her three friends] might be bored it was fantastic to be greeted with lots of help and bat detectors, live bats, box-bat, the star Rob Strachan, information that’s not in books, rich bat habitat and an unexpected bat species!....... Thank you again for a memorable evening we all enjoyed, Vicky”. Our Beacon for Bats News December 2012 Page 5 The BBC comes to the Usk Valley By Hilary Macmillan, Communications Manager We’ve had some good publicity for the OB4B Project thanks to two BBC Programmes: Radio Four’s The Living World and BBC One’s Countryfile. Both pieces were recorded at one of the VWT’s lesser horseshoe bat roosts in the upper Usk Valley, where Henry Schofield and Jane Sedgeley discussed the Trust’s conservation work with the species.
