Thanks above all to the environmental diversity of this mountainous - alpine belt and the scarce human presence in the territory, the Friuli Dolomiti Alps Natural Park offers an exceptionally rich heritage of fauna.

The Park features stable populations of chamois, roe deer, marmots, wood grouses, black grouses, deer, and an already established and steadily growing herd of steenboks.

The Park's degree of freedom from contamination and wilderness is illustrated by the density of population of the golden eagle, and one nesting pair in each valley has been estimated.
