The forest, despite the deforestation, blazes and arsons that have occurred over the centuries, has almost completely preserved its canopy and hosts a peculiar biodiversity. Among the animal species are to mention the roe deer, the badger, the wild cat and many species of birds, like woodpeckers, the eagle owl and sparrows.
The Foresta Umbra is well known by those who love birdwatching or naturalistic photography enthusiasts.
