Areas in Dominante Humid (ZDH) in the territories of Alsace, the Regional Natural Park of the Vosges du Nord (PNRVN) and the Regional Natural Park of Ballons des Vosges (PNRBV)

Wet-dominated mappings correspond to alert mapping; they define areas with a high probability of wetlands where the wet character under the Water Act cannot be 100 % certified. These are areas identified as particularly rich a priori in wetlands, therefore requiring special vigilance in this regard in relation to the rest of the territory (which, of course, may also contain wetlands but at a lower density).
