It is far from imagining that here, in the 18th century and until the first half of the 20th century, human activity, linked to peat extraction, was in full swing. And yet these bodies of water bear witness to this exploitation in the past. The arrival of coal put an end to this activity and nature has now reclaimed its rights. Without human intervention, these plains would naturally fill up and make way for a reed bed and then for a peat basin.
