Marais de Pravet - Espace Naturel Sensible
Located at an altitude of 1,080 meters, this marsh nestled in the hollow of the Tréminis cirque is a refreshing oasis, shaped by mountain streams and forestry activities.
It is home to a mosaic of diverse habitats teeming with biodiversity!
This marsh is unique in that it lies along the line of mountain passes connecting the Northern Alps to the Southern Alps, right in the heart of a climatic transition zone. As a result, plants with Mediterranean affinities, such as the Montpellier thistle, and others that thrive in colder conditions, such as the beautiful marsh marigold, coexist within a small area.
