MTB 2 - a carpet of green

Before 1861, the house at the Col de la Serreyrède was inhabited by two families of farmers. They owned some livestock and had a vegetable garden, whose terraces you can still see above the La Caumette track. From 1861 on, the farm was inhabited by a forest ranger. It was only bought by the state body Eaux et Forêts in 1883, to be turned into a forester's house. It became one of Georges Fabre's headquarters during the reforestation of the Aigoual massif. The Cévennes National Park, tourism office and Terres d'Aigoual growers have now joined forces to revive La Serreyrède with the help of the Communauté de Communes Causses Aigoual Cévennes – Terres solidaires.

The Cévennes National Park rents out part of the building to the association, enabling local farmers to sell their products directly to the public. The association brings together farmers who wish to promote what they produce and share their know-how. They also enjoy sharing their vision of farming- high quality produce and products,

- human-sized farms,

- mutual aid.

Around 1850, before reforestation began, the inhabitants of the Cevennes were using local wood resources on a massive scale for heating and in industry, especially spinning-mills. Gradually, only a few beech copses remained, which were cut every 25 to 40 years. Grazing by tens of thousands of sheep further reduced the herbaceous plant cover. Much weakened, the plant cover was then also subjected to heavy precipitation, the so-called Cevenol episodes. It is against this backdrop that the lengthy work of the foresters began. To reduce risks and establish a lasting forest cover, the first technique was to make use of what was already present by converting the disused copses into mature plantations.

This peat bog was a site for experiments and research by Charles Flahault. Flahault, who studied the geographical distribution of species, was interested in what was then known as acclimatisation (adaptiaton to local environmental conditions). He attempted to introduce 200 plants from 40 non-indigenous species to Le Trévezel peat bog, echoing the way tree species were introduced into arboretums. The peat bog's history and the way it works are described in detail on the panel (in French only).

In the 19th century, Mont Aigoual was almost totally bare of trees. Intensive use of the forest and the pressure of transhumant grazing together with the harsh local climate caused devastating floods. The rich vegetation of the grazing grounds was replaced by heather pastures and many gullies. In the valleys huddling at the foot of Mont Aigoual, terrible floods pushing tons of stones downstream carried off roads and pastureland. In response, a reforestation programme was launched in the second half of the 19th century, which created the forest you see today. Nowadays, the forested Aigoual massif protects the valleys while at the same time providing a space for economic production, biodiversity and leisure.

This tree population consists of trees of very different diameters, ages and heights. Species are mixed: mainly pine, but also beech, rowan and whitebeam. This is an irregular mature forest, a forestry dynamic that is interesting for several reasons: it creates permanent forest cover; resistance to soil erosion; better resilience against storms or parasite attacks; regular production, etc. In the small clearing to the left of the path, the sunlight now penetrating to the forest floor has made natural regeneration of beech and fir possible, ensuring the renewal of the forest.

Another method of creating a durable forest cover is to plant or sow. This work is carried out either on bare soil or among existing tree stands. The Aigoual reforestation programme was a gigantic effort, requiring 900,000 days of work, the planting of 60 million conifers and 7 million deciduous trees, and sowing of 38 tonnes of seeds. Spruces and pines, which can be planted in full sunlight and grow quite quickly, were widely used. Under the forest canopy, preference was given to firs.
