Home to some rare Alpine species, the Stelvio National Park has one of the largest concentrations of marmots and golden eagles in the entire region. There are presently 26 pairs of golden eagles in the nature reserve, eight of which inhabit the areas of the national park in South Tyrol. After almost disappearing at the start of the 20th Century, populations of ibex, chamois and red deer are also now on the increase in the Central Alps. A number of creatures have also made this natural reserve their home, including over 20 different bat species.

The bearded vulture, which had been alienated from its ancestral habitat only a few decades ago, has now been reinstated. Such achievements demonstrate how effective scientific research can support and protect the indigenous wildlife in Europe.

The majestic bearded vulture is a prime example of successful nature conservation. Ever since the first clutch of eleven chicks was successfully reintroduced to the Stelvio National Park in 2008, the population has expanded to 27 young adults.

In the reserve, there have also been sightings of shy predators such as lynx, brown bear and even the occasional wolf.
