  Fauna

  The Eurasian pygmy owl

  The call of this small, nocturnal bird of prey can be heard in the spring, and also in the autumn when it can utter some peculiar sounds. Active during daytime hours and at dusk, the pygmy owl is a predator of passerine birds and small forest rodents. But when they spot it, passerines will come together in large numbers to mob it, so as to prevent any attempted surprise attack. It is restricted to mountain forests where it seeks out trees with woodpecker cavities in which it builds its nest.

  Pass

  The Col de la Pousterle

  A pousterle (in the local high-alpine Occitan language) is a small gate, a postern. It comes from the Latin posterula which means back door. This place name is sometimes given to a pass, which could be described as a gateway between two valleys! The glaciers carved out this gateway through which an arm stretched between the glacier occupying the Fournel valley and the glacier flowing down the Vallouise valley.

  Flora

  The larch

  The symbol of the Southern Alps, this softwood tree loses its leaves in winter, and is swathed with gold and lights up the mountains in autumn. The larch forests are maintained by the grazing of flocks. Without them, other trees like the fir or other pine trees could grow, creating a different kind of forest. A pioneer species, the larch establishes freely in light conditions. Its solid rot-proof wood has always been used in the construction of houses.

  Fauna

  Forest-dwelling bats

  Bats don't just live in caves! In summer, some forest-dwelling species shelter in old hollow trees or woodpecker holes during the day. Sometimes, the females also form little colonies here, where their young will be born (one bat pup per female). In this forest, which is still young with very few old trees, artificial roosts have been installed to help the bats and to facilitate their study.

  Panorama

  Tournoux

  The Tournoux plateau is a small paradise with its cool meadows, its occasional renovated chalets made from stone and larch wood and its view over the Tête d'Aval, an imposing limestone peak forming part of the Montbrison massif. Whether on a mountain bike, on foot or on cross-country skis in the winter, this spot is always an invitation to stop for a break!

  Fauna

  The common raven

  A hollow "caw" makes you lift up your head (careful not to trip!). A pair of common ravens is nesting near here (they pair for life), on a cliff face. Although bigger than its cousins the carrion crow and the rook, it can be identified by its rather lozenge-shaped tail. It almost became extinct due to persecution Yet it's an omnivore and, more particularly, a scavenger which plays an important role by cleaning up disease-prone carcasses.

  Panorama

  The Fournel valley

  This is the southern side of the Col de la Pousterle and its view over the very long Fournel valley, known for its mines, ice waterfalls, blue thistles, its canyon and other treasures. Lower down is L'Argentière-la-Bessée. At the highest point, right in the distance, is the Champsaur!

  Vernacular heritage

  Le Laus

  A number of old alpine pasture chalets or hamlets, often renovated, are dotted across the Puy-Saint-Vincent resort. These are the Chalets du Laus. Le Laus is a place name designating a lake. In fact, just after the chalets, although not a lake, there is a flat, marshy area which is no doubt a small filled-in lake. So no point in bringing your pedalo!

  Reading the landscape

  The Vallouise valley is a tributary valley on the right-hand bank of the Durance. It is made up of three municipalities: Vallouise-Pelvoux, Les Vigneaux and, looking down from the heights, Puy-Saint-Vincent. This 25 km-long valley is dominated by numerous peaks, ranging in altitude from 980 metres, at the confluence of the Durance, to the peak of the Barre des Écrins at 4,102 metres (the highest point in the Les Écrins massif) and covers 18,541 hectares. Lying at the centre of the crystalline massif, the Vallouise valley is the gateway to the Parc National des Écrins and boasts exceptional and varied landscapes and a diverse wealth of fauna and flora.
