Bourget Marshes

The Bourget marsh in Cervières is part of the Rochebrune-Izoard-Vallée de la Cerveyrette Natura 2000 site. A natural area of ecological, faunistic, and floristic interest, this marsh is one of the largest peatland complexes in the Southern Alps.
The Bourget de la Cerveyrette marsh is an exceptional complex of wetland habitats combining various swamps, peat bogs, lakes, and fens.

Three remarkable environments are listed there:
Transitional peat bogs, high-altitude fens on the edges of springs, and arctic-alpine pioneer fens. These are environments of great heritage value, with a very characteristic floristic composition.
