The Manche department in Normandy, France, is a land of breathtaking landscapes, where rugged coastlines, lush wetlands, and serene forests create a haven for biodiversity. Among its most treasured gems are the Sensitive Natural Areas (Espaces Naturels Sensibles, or ENS), protected zones that safeguard fragile ecosystems while allowing visitors to connect with nature.
If you’re curious about these remarkable places—their history, ecological importance, and the efforts to preserve them—this guide will take you on an inspiring journey through Manche’s wild heart.
What Are Sensitive Natural Areas (ENS)?
Established to protect regions of exceptional ecological value, Sensitive Natural Areas (ENS) are designated by local authorities to conserve biodiversity, restore habitats, and promote sustainable public access. These areas may include:
- Coastal dunes (like the Hague Peninsula)
- Wetlands and marshes (such as the Marais du Cotentin et du Bessin)
- Forests and heathlands (like the Landes de Lessay)
- Peat bogs and rare floral reserves
The Manche department has prioritized the preservation of these sites, recognizing their role in maintaining ecological balance and offering sanctuary to endangered species.
A Glimpse into the History of ENS in Manche
The protection of Manche’s natural heritage is a story of vision, conservation, and community effort.
Early Recognition of Natural Wealth
Long before modern conservation laws, the unique landscapes of Manche were appreciated for their beauty and resources. The marshlands of Cotentin, for example, were shaped by centuries of human interaction—used for grazing, peat extraction, and flood control.
The Birth of ENS in France
The concept of Sensitive Natural Areas emerged in the 1970s and 1980s, as France recognized the need to protect its most vulnerable ecosystems. Local departments were given the power to acquire and manage these lands, ensuring their preservation for future generations.
Manche’s Commitment to Nature
In the 1990s and 2000s, the Manche department intensified its efforts:
- Purchasing critical habitats to prevent urban sprawl
- Restoring degraded ecosystems (such as dunes and wetlands)
- Creating educational programs to raise awareness
Today, over 50 ENS sites are protected across Manche, each with its own story of resilience and renewal.
Exploring Manche’s Most Remarkable ENS Sites
1. The Dunes of Hatainville
📍 Near Barneville-Carteret

- Protected since the 1990s to combat erosion and habitat loss.
2. The Marais du Cotentin et du Bessin
📍 Across the Cotentin Peninsula
- A UNESCO Biosphere Reserve, this vast wetland shelters migratory birds, otters, and unique flora.
- Once threatened by drainage for agriculture, now a model of sustainable conservation.
3. The Landes de Lessay
📍 Near Lessay
- One of the largest heathlands in France, with purple moor grass and wild orchids.
- Managed through traditional grazing to maintain biodiversity.
4. The Val de Saire Wetlands
📍 Northeast of Cherbourg
- A mosaic of ponds, reed beds, and meadows, vital for amphibians and birds.
- A success story of ecological restoration after years of neglect.
Why Protecting These Areas Matters
The ENS of Manche are more than just beautiful landscapes—they are lifelines for biodiversity and climate resilience.
- Wildlife Sanctuaries: They provide refuge for endangered species like the European otter, marsh harrier, and natterjack toad.
- Carbon Sinks: Peat bogs and wetlands store vast amounts of CO₂, helping fight climate change.
- Natural Barriers: Dunes and marshes protect inland areas from storms and flooding.
- Cultural Heritage: Many sites hold traces of ancient human settlements, linking nature and history.
