In the Park, the flora of each region is related to several factors such as climate and altitude. Up to 1200m, the vegetation is very dense. It is anticipated that the forests of the park were originally dominated by oak (Quercus). It is still possible to find some areas of original forest, particularly in the Forest of Hostels, Forest Cabril, Mata Mata and the Bered the Ramiscal. These are conservation areas with limited access.

 

The forests can be divided into two distinct types of biotopes: the forest of oak forest of Albariño and Pyrenean oak. The first occurs at low altitudes in hot valleys and sheltered. Here, apart from Albariño oak (Quercus robur), are the butcher's broom (Ruscus lusitanica), the Tree (Arbutus unedo) and azereiro (Prunus lusitanica), among others.

 

The forest of Pyrenean oak occurs in higher altitudes between 1200m and 1400m, the mountain called floor. Here, beyond the Pyrenean oak (Quercus pyrenaica), can be found in the blueberries (Vaccinium myrtillus), holly (Ilex aquifolium), birch (Betula pubescens Celtiberian and Birch), the yew (Taxus baccata) and pine. Above 1400m remaining juniper and low shrubs.

The fauna of the park area is notable for the quantity and diversity of animals worthy of interest that it can be found, having been reported as 226 vertebrate species protected under the Berne Convention, of which 65 belong to the list of threatened species of the Red Book Portugal.

 

The pony is a small horse that runs through the mountains and the park is no stranger to those who visit. Many of them are no longer wild and belong to the villagers, but prowling the mountains. There also remains a wild boar, fox, badger, otter, wildcat (Felis silvestris), the weasel, shrew-of-the-teeth red (Sorex granarius), marten (Martes martes) and squirrel (Sciurus vulgaris ). There are also species that have been disappearing, as the wolf and roe deer, in addition to the ponies.

 

The wolf (Canis lupus), almost extinct throughout the country, there still remains the Peneda-Geres, though with little representation.
