Here, the peripheries of peat bogs are still grazed on. These wet meadows, which are characterised by the presence of a large amount of water in the soil, are also very rich for biodiversity. Some flowers, such as the bird’s-eye primrose, particularly flourish here.
These are also areas of transition between the rest of the valley and the peat bog, and between the lake and the river. They filter water through the soil, eliminating nitrate, which limits the pollution of groundwater. Their presence is therefore vital to properly maintain a peat bog.
