Tourbière De La Morte Femme

Tourbière de la Morte Femme is a protected peatland tucked into the forests west of Gérardmer, in the French Vosges mountains. The name — literally "peat bog of the dead woman" — tends to catch visitors' attention, though the site itself is known first and foremost for its ecological value rather than for any documented story behind the name. It sits within the Gérardmer Ouest state forest, close to other protected patches such as the Faignes de Noir Rupt, and forms one of the more distinctive natural features of this part of the Vosges.

How did this peat bog form?

The bog occupies the basin of a former glacial lake that appeared once the ice filling the valley stretching from today's Lac de Gérardmer toward Le Tholy retreated. That lake gradually disappeared through natural infilling with organic sediment roughly 7,000 years ago, leaving behind the waterlogged, peat-rich environment visible today. This slow process, spanning thousands of years, produced the mosaic of woodland and open, humid ground that now defines the landscape.

Why does this site matter ecologically?

The mix of dense forest and open valley-floor patches makes the landscape stand out clearly from the rest of the Vosges massif. It is one of the few places in the region where mountain pine (a hooked-cone pine variety native to high-altitude sites) grows naturally, adding further scenic and ecological weight to the area. The peatland supports species tied to wetland habitats, including the scarce large copper butterfly, protected under the EU Habitats Directive, and a dragonfly known locally as the northern damselfly. Among the plants typical of peat bogs, visitors can find bog rosemary, round-leaved sundew, and marsh calla — all classic indicator species for this kind of ecosystem.

What is the history of peat extraction here?

During the Second World War and continuing until 1948, peat was extracted here on a significant scale to substitute for coal and gas, both in short supply at the time. Traces of that extraction — old cuttings and reshaped ground — can still be read in the terrain, even though the site has since been under protection for decades and has been gradually returning to a more natural state.

What is the site's current protection status?

Tourbière de la Morte Femme is part of the Natura 2000 network, forming a piece of a wider protected area that includes the Gérardmer Ouest forest. Conservation work here focuses on limiting the drying-out of the peatland, including backfilling old drainage ditches and monitoring the quality of water entering the reserve. The goal is to restore hydrological conditions that allow the peat bog to regenerate naturally and continue supporting the rare species that depend on it.

Frequently asked questions

Can you visit the peat bog on your own? The site lies within a state forest and a designated biological reserve, so it's best to stick to marked trails to avoid damaging the fragile peatland habitat.

Where does the name "Morte Femme" come from? The name has been used locally for a long time, but the available ecological and administrative sources don't explain its origin — they focus instead on the site's environmental importance.

What else is worth seeing nearby? Neighbouring sections of the Gérardmer Ouest forest, including the Faignes de Noir Rupt, form a larger network of protected peatlands and Vosges woodland worth exploring together with this site.
