8 points of interest

  • Fauna

    The black woodpecker

    Sporting a black cap, the black woodpecker is the biggest of the woodpecker family. Wary and solitary, it is difficult to spot, but its strident calls give its presence away. It feeds mainly on ants and insects living in dead trees, which it extracts by hammering into the wood. It hollows out a nest hole in trees. Once the young have left the nest, it may be taken over by owls or forest-dwelling bats.  

  • Flora

    The violet bird's-nest orchid

    In the pine forest undergrowth stands a large, completely purple orchid. It has no leaves, just a few whitish scales on the stem. Lacking chlorophyll (the green plant pigment which plays a role in photosynthesis, the process that allows the production of organic matter), it lives as a parasite on tree roots.

  • Flora

    The Scots pine

    A long trunk that is reddish-brown towards the top, sparse foliage, grey-green needles grouped in pairs... It has to be the Scots pine. Happy in poor soil, this softwood tree can withstand below-zero temperatures as well as summer droughts, and so it is very common in intra-alpine valleys with a continental climate, like the Vallouise.

  • Vernacular heritage

    The hamlet of Parcher

    The hamlet of Grand Parcher stands on the alluvial cone formed by the Grand Parcher mountain stream, and on either side of it. It is made up of several old houses and the seventeenth-century chapel of Saint-André. It has two sun dials painted onto its walls. One of them bears the saying HORA INCERTA CUNTIS, ULTIMA MULTIS (This hour is uncertain for all, it is the last hour for many). Food for thought!
  • Water

    Thne Gyronde

    No, we're not in south-west France where the Gironde flows! The Gyronde (spelt with a «y»!) is the river that flows between Vallouise and L'Argentière-La Bessée, where it flows into the Durance. It originates from the Gyr and Onde mountain streams which merge in Vallouise.

  • Fauna

    The long-tailed tit

    Some birds are causing a stir in a tree, constantly coming and going and uttering little calls. They are round and black and pinkish beige in colour with a long tails, hence their name, the long-tailed tit. They are resident birds and always live in small groups. They inhabit forests, undergrowth and even gardens. They weave a ball-shaped nest out of lichen, moss and dry grass.

  • Flora

    Wood cranesbill

    The path is edged with large clumps of a plant with purple flowers, the wood cranesbill. The leaves are palmate and divided into 5 to 7 incised and indented lobes, This common plant grows in meadows and cool woods. The «geraniums» we see on balconies are in fact pelargoniums, distant cousins originally from South Africa and cultivated for ornamental purposes.

  • Fauna

    The Alpine copse snail

    On the damp banks of the stream, hidden in the grass, is a snail with a beautiful golden brown shell speckled with brown, decorated with a dark spiral stripe. It has a black body. The alpine copse snail is relatively rare and, as its name suggests, it is found in the Alps. It is a sub-species of the ordinary copse snail, which is present across Europe.
