"It's been a harsh winter with lots of wildlife suffering from the cold but one of the Meirionnydd colonies of rare, lesser horseshoe bats, seems to be thriving".
"Sunday, 7 February was the agreed date for the count organised by the Gwynedd Bat Group".
"I lowered myself into the flooded mine adit, with frog spawn at the entrance and my waders filled with water through the cracked rubber!"
"With hard hats, torches and clickers we made our way to the end of the 200 foot long adit, counting as we went".
"The total was 113, significantly up from 74 this time last year. Lucky horseshoes!"
"Bats are protected by law and should not be disturbed".
"The counting of bats during hibernation surveys is done under supervision and with permission of licenced bat workers".
