The Langazel moors

Why take advantage?

This is the oldest known peat bog in western Brittany. Useful in the fight against the extinction of certain species, this wetland requires a great deal of attention. The Langazel wetland is located in the communes of Trémaouézan, Ploudaniel and Plouédern, and is one of the main sources of the Aber-Wrac'h stream, which supplies 36 communes with drinking water. In a rural environment with a strong agricultural vocation, wet meadows, wet moors, low marshes, willow groves and other woods mark a break in the landscape. This is certainly one of the last large inland wetlands in the Finistère region of Léon. Wet meadows: These are areas of exceptional diversity, despite the poor mineral content of the soil. They are home to a multitude of grasses and rushes, as well as remarkable species such as Marsh Lousewort. Acidic peat bog and low marsh groupings: These are home to many heritage species, including Rossolis, Sphaignes, Rhynchospore and Linaigrette. They are found in certain former peat extraction pits and on peaty or silty substrates. Heath: Mainly composed of heather, gorse and grasses. It is home to rare and protected species (such as certain insectivorous plants). Once mown, this environment is now colonized by pine trees if left untended. The process of peat formation began 11700 years ago, and since then vegetation has gradually colonized the original water bodies. Peat is a vegetable soil made up of plant debris which, due to the lack of oxygen, cannot decompose. Once dried, it becomes combustible. In Langazel, this resource was exploited for many years to heat homes and factories in Brest and Landerneau. Even today, as you stroll around the site, you can still make out the old peat extraction pits.
The Langazel hiking trail (8 km, 3 to 3 hours, starts in front of the school) takes in the different landscapes, moors, wet meadows and peat bogs. Within this circuit, a 30-minute interpretation trail explains the evolution and formation of moors and peat bogs.
