Start : Vallouise - the Casse

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.

Vallouise Pelvoux is a municipality within the Parc National des Écrins. Renovated in 2014, the Park Centre ("Maison du Parc") houses the offices of the local Park staff and has a spacious visitor reception area. It offers a permanent interactive exhibition inviting discovery of the territory and its heritage features, a temporary exhibition space on the upper floor and an audiovisual room (screenings and talks). It is currently in the process of applying for the "Tourisme et Handicap" tourism and disability label. Admission is free and so, too, are most of the activities in offer.

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.

So what is the identity of this sun bird? It's the royal, or golden, eagle of course. Although it is telling the time here, in the surrounding natural landscape it hunts marmots. But what becomes of it in winter when the marmots hibernate deep in their burrows? It's a lean time. It has to make do with a hare or ptarmigan, and in particular the carcasses of chamois which have not survived the winter or have been killed in an avalanche.  

Even in winter, the ash can be recognised from its large black leaf buds. The leaves are compound. A pioneer species that grows easily, the ash has long been used by man for everyday needs: its foliage was used to feed cattle and its hard, flexible wood was used to make a variety of objects such as tool handles. Its French name frêne often appears in local place names too: Freissinières (frêne noir - black ash), Le Freney etc. Evidence of its historical importance to human communities.. 

Some strange creatures are moving jerkily over the surface of the water: Gerrises, insects related to bedbugs. Like a true insect, they have six legs and they «skate» across the water using their intermediate and hind legs which are covered in hairs to make them water-resistant. They are carnivorous and anything on the water surface, dead or alive, is good to eat! They catch their prey with the forelegs, sucking up the juices with their strong proboscis!

With its strident calls, this little acrobat gets itself noticed. With a blue-grey back and a black stripe over its eyes, it works its way down the tree trunks upside down in search of insects. It nests in old woodpecker nests but if the diameter of the entrance is too large it reduces it with mud, to protect its young from predators. Hence its French name torchepot (a reference to edging the rim of a vessel). 

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.
