Conservationists and volunteers are being encouraged to sign up for this year’s Norfolk Bat Survey.
The initiative, which is run by the British Trust for Ornithology (BTO) aims to collect current information about what species of bat can be found in the county and where they are living.
Volunteers can reserve an area of one square kilometre, within which three points have to be observed using automated detectors, which record the bats’ calls. The sounds are then analysed through a computer system.
Twenty-one monitoring centres have been set up across the county, from where volunteers can obtain the equipment they need to take part in the survey.
The list includes the libraries in Gaywood and Swaffham, as well as the RSPB reserve at Titchwell, the RSPCA Welney wetland centre, Oxburgh Hall, near Swaffham, and the Hawk and Owl Trust site at Sculthorpe Moor, near Fakenham.
Anyone who is interested in taking part in the survey can go online to www.batsurvey.org/sign-up for more information.
