The marsh

n the locality known as Les Olliviers, there is a marshy area. Damp habitats like this constitute rich and diverse ecosystems. Most of them developed naturally. Wetlands have long been regarded as unhealthy and hostile environments. The requirement for urban land led to these areas being dried out. Today, wet areas are recognised for their heritage and functional benefits, as they hold remarkable biodiversity. This new awareness has led to their usage being regulated in order to protect them.
