The peat bog

This fragile environment is quite exceptional. Formed as a result of vegetation that has badly decomposed due to a lack of oxygen, this water-logged soil offers a unique habitat to the species living here. Such species are well adapted to this environment and most could not survive elsewhere. The Lac-des-Rouges-Truites peat bog is home to many species. Examples are rare species such as sphagnum obtusum: a sphagnum, peat moss, which only exists in France in a peat bog in the Cantal and here; and the round-mouthed whorl snail, a very small snail that was once believe to be extinct in France, before being found only here in 2014.
