Other short-grass prairies?
After the forest, which is a farmed and worked space, foresters clear areas such as here, where other plant communities establish themselves: peat bogs, meadows, track verges. On the return leg, two large grasses will attract your attention: great yellow gentian with its yellow flowers and a more recent arrival, rosebay willowherb (fireweed), whose fruit “explode” into cottony masses at the end of the summer, when ripe.
From 1964 onwards, large reforestation programmes were undertaken by companies using machines. The linear and regular layout of these plantations makes them easy to distinguish from older ones.
The prairie's botanical rivals
Below you, vast areas have been planted with pines and other conifers. The interest and regional and European rarity of short-grass prairies mean that they must be clearly demarcated from the forest. In fact, natural seeding of pines, carried onto the prairie by the south wind, has created a new forest. This plant dynamic, which is entirely logical at the altitude, gives the forest the upper hand over the prairie. The European Union is currently helping local participants to fell these new trees so as to protect the prairie. On your return leg, you will see other indigenous tree species which could encroach on the prairie in the same way (beech, birch).
An endangered landscape
This vast expanse of short-grass prairie, an area of historical and natural heritage, is endangered today. The surface area of this relic has been much reduced over the past few decades. While the summits are made stable by the prairie, the mountain side presents evidence of erosion (denuded rocks) that is the result of foresters’ attempts at reforestation. On the ledge, pines are starting to establish themselves at the expense of the prairie. These zones have become fragile and need better management of all the territory’s elements. Shepherds will have to guide their flocks carefully here, so as to avoid making erosion worse but also to eliminate pine seedlings.
Vertebrates benefit from the plants or from small prey, especially hares or the common lizards with its thick tail, which is coveted by the reptile-eating short-toed snake eagle. Among the birds of prey, you may spot the characteristic silhouette of a Montagu’s harrier or hen harrier, with their low contour-hugging flight. Among the many passerines, you may spot the Northern wheatear, a summer guest, sitting on a stone, or more rarely a grey partridge. If you listen, you may well hear larks singing.
Low-growing plants and shrubs
A large amount of sunshine encourages many low-growing grasses from other botanical families to appear among the fescue and nard. They are almost all perennial. They form a veritable tangle of plants. Among the pretty alpine flowers are the spring pasque flower and the blue dwarf spring gentian in summer. Other, smaller plants are perfectly capable of “making holes” in a short-grass prairie that is less intensely grazed than before. Grass networks that lose in density develop weak points that shrubs exploit to grow at the very heart of the prairie: blueberries, which are here associated with lingonberries (cowberries) and calluna, a type of heather.
Small grassland creatures
Each spring, a demographic explosion of fauna prepares itself to burst forth in the summer. Earlier in the year, the thousands of small creatures to be seen here have not yet finished their metamorphoses, and the various species are difficult to recognise as larvae. Subalpine short-grass prairies attract a specific mountain fauna that is getting rarer everywhere else in Europe, such as the Stauroderus scalaris cricket, which tirelessly enlivens the pastures with its summer concerts. Crickets only eat plant matter whereas grasshoppers, such as the wart-biter, tend to be carnivorous. Many butterflies visit the flowers.
Subalpine short-grass prairie
Like garden or sports pitches, short-grass prairies are shaped by mankind. Grazing and controlled burns are the tools for their maintenance here. The main plants are nard and fescue, perennial grasses related to wheat. If you cut (graze) one of their stalks, five more will soon form; if you trample them, they multiply and become very dense. This kind of “torture” creates a thick plant cover that stabilises the sparse dark soil, which is derived from erosion of the ever-present granite. Here, then, are some clues for the appropriate management of this environment, which becomes weakened if neglected.
Starting at “Col de Finiels” make for “Bas du Col Plat”, then “Col Plat”, “Font de Sènebébios”, “Le Cougnet”. Walk downhill to “Pont de la Colinie”. Then walk to “Sommet de Finiels” via “Travers de l’Homme”, “Abri forestier de Mallevrière”, “Valat de la Mouline”, “Route forestière des Crêtes”. At “Sommet de Finiels” return to “Col de Finiels” via “Col de la Draille” x2, then “Sous le Col de Finiels”, “Col de Finiels”.
