In the heart of the Marais Poitevin regional nature park, the second-largest wetland in France, a scientific team led by a CNRS researcher has demonstrated the ability of clay soils to self-organize into geometric patterns. Known as mottureaux, these microreliefs, similar to hummocks, channel rainwater infiltration and promote plant biodiversity in marsh soils.
