Le Trévezel molière (peat bog)

Marker 3A peat bog is a thick layer of plant cover that has decayed little or not at all because of accumulated water, acid soils and the cold climate. This wetland has hardly changed for centuries. Once called molières, soulages, sagnes or fanga, these environments were long denigrated and “cleaned up”. Today, they are known to be well worth preserving. Peat bogs are home to a great variety of more or less specific species, such as the sundew, a little carnivorous plant.
