Fauna

The vertebrates living in the National Park are typical of Alpine areas.

Conditions for life in these areas are extremely harsh and only a few species are able to survive, using the scarce resources available over the whole year. Sudden and significant changes in temperature, strong winds, rarefied air (with less oxygen available), long winters with very low temperatures, significant snowfall with snow cover lasting for several months and low availability of food are just some of the challenges which animals must deal with to live in such an environment.

Here, we find opportunistic species, from across the ecological spectrum, with an outstanding capacity for adaptation, species which can cope with the scarcity of food in winter using different strategies, such as migration, and more delicate species (very specifically adapted to certain ecological conditions) which have evolved to their environments with the sort of restrictive properties listed above, which therefore are adapted to the low temperatures and lingering snow cover.
