The Marshes and Peat lands 
Whether tufaceous, peaty, acid or alkaline, marshes are very abundant in the region.
The marshes, like all the other wetlands in the region, are natural areas which it is important to preserve. They form a very rich reserve of biodiversity and play a crucial role in the water cycle and the quality of our drinking water.
The Germont-Buzancy marsh (Ardennes)
This 350-ha marsh is the largest alkaline bog in Champagne-Ardenne. Plants degrade very slowly and accumulate in the soil. The bog is rich in plant species, including 30 which are rare or endangered in the region such as the Marsh Sow-thistle (a giant herbaceous species which can grow to 3 metres).
The marshes of Saint-Gond (Marne)
This vast wetland covers about 18 km and 2,000 ha, around the River Petit Morin. Many small natural habitats rub shoulders here (marshes, wet and dry meadows, peat land, woods...). This diversity is home to 127 species of nesting birds and rare species of carnivores such as the pine marten and the wild cat.
The Ramerupt pond (Petit Mesnil – Aube)
The Ramerupt pond, of about thirty hectares, is one of the few still to exist in the south-west of wetland Champagne. Its reed beds make it a paradise for many species of birds.
The Grands Prés Marsh (Saucourt-sur-Rognon – Haute-Marne)
Located in the bed of the River Rognon, this 5 ha marsh consists of meadows, meanders of the river, a reed bed and a wetland. It is a major site for the reproduction of amphibians and is home to a remarkable fauna. A trail has recently been set up on duck boards for visitors to explore the site.
