The protected area is divided into two valleys, submerged by the sea in very ancient geological periods. Today it consists of a hilly territory where wild valleys covered with woodlands follow one after the other. The establishment of the Reserve mainly aims at protecting the paleontological heritage represented by fossils which have been found in some sedimentary strata outcropping along the walls of the valleys. They date back to the Pliocene (5-1.8 million years ago), when the sea covered the whole Po Plain up to the Alpine chain. Valle Andona and Valle Botto Reserve, including now also Valle Grande, also offers the opportunity to carry out interesting naturalistic observations. The hilly slopes which were once mainy cultivated with vineyards are nowadays covered with black locust trees, hornbeams, and British oak woods. The undergrowth is dominated by hazelnut tree, spindle tree, honeysuckle, and traveller's joy. |
