Other mammals in the Park
Better and less well-known species
The Park's biodiversity is well reflected in the mammals too: in addition to the six species of ungulates and twenty species of bats, in the protected area there are about thirty other species of terrestrial mammals, from the better to the less well-known. Let's see some of them.
The fox (Vulpes vulpes) is the commonest predatory carnivore and, thanks to its adaptability, is present in every environment. Their activity is mostly crepuscular or nocturnal, but it is possible to see them roaming in broad daylight on high altitude prairies hunting marmots and small rodents or looking for pheasant's eggs.
A typical alpine species is the mountain hare (Lepus timidus), a beautiful rodent that frequents the subalpine prairies and the rhododendron and bilberry patches. The mountain hare changes it coat from ochre-grey in summer to white in winter, always remaining extremely well camouflaged. The squirrel (Sciurus vulgaris) and the dormouse (Glis glis) are, on the other hand, two small rodents that are quite easy to observe in the woods at the bottom of the valley.
The Park is also home to five species of insectivores usually grouped together with mice, but in reality they are quite distinct from them: they are the so-called shrews. Some species frequent the woods and meadows (such as the Sorex araneus), others the humid or aquatic environments (Neomys sp.). These animals are extremely elusive and difficult to study, the only reports often concern specimens found dead along the paths, a fairly frequent event after a heavy storm. Particularly rare is the alpine shrew (Sorex alpinus), present in Piedmont and Aosta Valley and only in very few other places.
