Peneda-Gerês National Park Fauna
Although some of the species are now extinct, such as the brown bear and the mountain goat, the National Park still presents a very varied fauna, with important species like the wolf, the roe deer, the wild boar, the fox, the wild ferret and the otter.

Of special importance among the bird species are the endangered royal eagle, the kite, the woodland screech owl and the titmouse. Among the reptiles the most important are the rarely found Seoane viper and the horned viper, as well as the water snake, the water lizard and the green lizard. Amphibians of special note are the rare Lusitanian salamander, the tritons, the Iberian frog and the midwife toad.

Peneda-Gerês National Park Flora
The typical vegetation of the region is oak. It is almost always the black oak that predominates, coexisting with an impressive diversity of ferns, mosses, lichen, mushrooms and other plants such as the endangered holly.

There are woods where the Gerês lily can be found, but the plants are mostly heather, genista, gorse, broom, gramineous plants and juniper. This latter, like the woodland pine, the yew, the white birch and the rare Gerês fern, is a true relic of glacial flora.

The varied climatic influences occasionally result in unexpected flora, with examples being the cork oak and the British oak. In the higher zones you can find areas that are always flooded, where the carnivorous plants, most particularly the "Orvalhinha", are a constant feature.
