It grows in coniferous and broad leaved forests, in the fields and glades. The fruit is harvested in the summer using a special rake and is eaten fresh and used to make jams and syrups.

Sandstone: sedimentary rock formed about 40 million years ago following great underwater landslides that brought huge quantities of detrital material and deposited it in deep sea. Along the path climbing to "Mount Libro Aperto" there are great layers of sandstone alternating with thinner layers of clay.

Rhododendron (Rhododendron ferrugineum L.) (Protected species): evergreen shrub with bell-shaped flowers with 5 purple-red petals. It grows in clusters on the rocks and bare soils rich in humus. On the northern side of "Mount Libor Aperto", flowering occurs during the first summer months.

Mount Maiori (1562 m): small range between the Abetone mountain pass and the "Foce alle Verginette". From the peak, easy to reach on path CAI no. 00 near the stone fountain, there is an impressive view of the Apennine ridge towards north and northeast, and of the peaks of the district of Abetone towards south.

Alpine Marmot (Marmota marmota): It was recently reintroduced in this area and spread on the rocky slopes between 1000 and 2000 m. It is about the size of a rabbit, with thick brown fur and lives in small colonies in deep underground holes, where it hibernates during winter. It is very active in daytime, feeding on grass, shoots and roots. It often sits still to check the territory and warns other animals of danger with a shrill whistle.
