It’s not a bog!
I had the pleasure of a guided tour around Cors Erddreiniog which is also known as Cae Gwyn or White Field on account of the marl. This nougat-looking malleable substance is calcium carbonate, deposited by lime-rich springs coursing through the fens.
It’s looking a real mess at the moment as 25,000 tonnes of top soil is being scraped off the top of an area about the size of 8 or 9 football pitches. All part of a much larger project to restore the Anglesey & Llŷn Fens which is a LIFE project with £3.5 million of European funding.
If you’re chatting with members of the project team don’t say that’s a lot to spend on a bog – they’ll soon put you right and point out the difference between a fen and a bog. Bogs fill from the top whilst fens fill from below.
You can hear the story on Country Focus (Radio Wales, 27th November) or see the action in this short film below.
