The number of rare bats in a Devon town has “plummeted”, a bat-observing group has said.

Be Buckfastleigh, a community interest group, said the decline of greater horseshoe bats in the town was “alarming”.

Director and resident Pam Barrett has been observing the protected species for about 10 years and said her group would normally expect to see around a thousand bats at this time of year.

However she said earlier this year they had counted “as few as 20” greater horseshoe bats in Buckfastleigh.
