An easy circuit departing from Prénovel which provides access to the adapted Nanchez peat bog, an exceptional natural site waiting to be discovered on foot along the boardwalk.

In the Prénovel forest, surrounded by greenery and flowery clearings, is the open combe of Nanchez. This combe is dominated by agricultural activities and features wetlands and peat bogs along the winding Nanchez river.

Know-how

Wood and peat

Whilst the forest has always been exploited in the region, fluctuations in the economic and social situation throughout history have shaped the landscape, alternating between thick forests and vast cultivated expanses. 
As from the 17th century and up until the 20th century, an increase in forest exploitation (with wood serving as fuel for economic activities such as blacksmiths) led peasants to use peat as fuel for their domestic use.

History & Heritage

The crown of the low walls

The capping on the low dry-stone walls, or crown, maintains and stabilises the sides (visible parts) of the wall. Without it, the stones, and particularly those at the top, would end up falling. Here, you can observe a technique in which large and relatively flat stones, called lauzes, are laid vertically and often stabilised by spacers in between.

Wood-turning workshops

More than a place of work or a rudimentary shelter for craftsmen, for those who occupied it, the workshop is a setting that is both intimate and public.
Between the tools used, on the worktops where sawdust is pushed away with the palm of a hand, is where craftsmen build their know-how, by the light shed by the large dusty windows.

Natural environments

The Nanchez peat bog

Peat bogs are characterised by a surface that is constantly water-logged, where peat forms and accumulates: it is a type of bedding made-up of dead vegetation which has badly decomposed due to the absence of oxygen. Life conditions are demanding in these environments and this means that the species that live here must adapt to the omnipresence of water, to a relatively cold climate and to the chemical composition of the soil.

History & Heritage

The evolution of life and buildings

The rural house was first the one belonging to the farmer and livestock breed, where men and animals lived together. As from the 18th century, cheese specialisation and the pooling of milk in cooperative structures - “fruitières” - brought farmers out of a self-subsistence economy. In terms of buildings, the farm became bigger: a storey is added to include bedrooms, a second stable is sometimes built to accommodate more animals.

Recommandations

The Nanchez peat bog must be visited on foot.

For an MTB outing, wear a helmet and bring enough water.

Paths are shared with pedestrians and horse riders, who have priority, therefore, please adapt and control your speed.

To use MTB paths, do not hesitate to get down from your bike.

This trail passes through pastures and forest paths. To respect the owners and farmers granting you passage, and for the security of livestock and wild fauna, we ask that you remain on the waymarked paths and close gates behind you where there are no MTB paths.

Wild flowers are beautiful, they may be rare and protected and often wilt quickly. Do not pick them! They will delight the next admirers.

In case of forest works (felling, skidding, etc.), for your safety, know when to stop and turn around.
