The Park is situated on the river terraces of the river Taro and of the stream Baganza, which date back to the Pleistocene. From a geological point of view, it is made of autochthonous soils of continental origin. The plateau is crossed by several watercourses, and the landscape is characterized by mixed broadleaved tree woods and, above all in the most external bends, by the sowable lands of the plain and by meadows. The main feature of the Park is the presence of mountain species (usually growing in the beech woods). In the upper plain strip Park's territory is without a doubt the richest area in vegetable species in general, and in species belonging to the protected spontaneous flora.
