Corno alle Scale Regional Park

Corno alle Scale Regional Park () is a regional park in the Bolognese Apennines, in Emilia-Romagna, northern Italy. It lies entirely within the municipality of Lizzano in Belvedere, in the Metropolitan City of Bologna, and protects part of the high Apennine ridge around Corno alle Scale, the highest summit of the Bolognese Apennines.

The park was established by Emilia-Romagna Regional Law no. 11 of 2 April 1988. The official regional technical sheet gives its area as and its elevation range as above sea level. It is managed by the Ente di gestione per i Parchi e la Biodiversità Emilia Orientale.

The protected area includes beech woods, chestnut groves, bilberry heaths, high-altitude grasslands, sandstone ridges, stream valleys, waterfalls and landforms shaped by former glacial activity. Its natural and cultural significance is linked to the combination of high-Apennine geomorphology, specialised montane habitats, historic woodland use and religious and rural settlements associated with the Dardagna, Silla and Rio Baricello valleys.

Geography

The park occupies the eastern part of the main ridge of the Bolognese Apennines, close to the watershed between Emilia-Romagna and Tuscany. It is centred on the upper valleys of the Dardagna and Silla streams and extends eastwards towards the Rio Baricello sector. To the west it borders the Alto Appennino Modenese Regional Park, also known as the Parco del Frignano.

The highest point is Corno alle Scale, which reaches above sea level according to the regional technical sheet. Other reliefs and landforms associated with the park include Monte La Nuda, Monte Cornaccio, Monte Pizzo, the Monti della Riva, Passo del Cancellino, Passo dei Tre Termini, the Cavone basin, the Balzi dell'Ora and the Dardagna waterfalls.

The name Corno alle Scale refers to the stepped appearance of the mountain. In Italian, scale means "stairs" or "steps", a name commonly linked to the visible sandstone strata of the massif.

Protected status and management

Corno alle Scale Regional Park was established to protect the natural heritage and biodiversity of the area. The regional technical sheet gives particular importance to summit and rocky environments, specialised species that are rare at regional and national level, and extensive forest formations, described as one of the most representative elements of the protected landscape.

The park is also associated with the Natura 2000 site IT4050002 Corno alle Scale, classified as both a Special Area of Conservation and a Special Protection Area. The regional Natura 2000 profile states that the site includes the whole regional park and is almost completely coincident with it.

Natural environment

Much of the park is covered by woodland. Chestnut groves and mixed broadleaved woods occur at lower elevations, while beech woods become dominant from about . Above the upper forest limit, from about , the vegetation opens into bilberry heath and high-altitude grasslands.

The upper part of the park has particular phytogeographical significance. Park sources describe the Corno alle Scale area as an important threshold for species linked to bilberry heath and alpine-type habitats, because farther south the Apennine ridge does not offer comparable altitude and climatic conditions. For this reason several plant species common on higher European mountains and in the Alps reach their southern distribution limit around the Corno alle Scale group.

The rocky cliffs of the park host rare plant species. These include Primula auricula, whose only regional station is recorded on the Balzi dell'Ora, and Geranium argenteum, described by park sources as a relict of Tertiary flora. Other montane and alpine species recorded in the area include Empetrum hermaphroditum, Gentiana nivalis, Lycopodium clavatum and Murbeckiella zanonii.

Fauna recorded in the park includes wolf, roe deer, wild boar, pine marten, snow vole, golden eagle, nightjar, red-backed shrike, woodlark, goshawk, wheatear, rock thrush and ring ouzel. The snow vole is recorded by the regional Natura 2000 profile in isolated high-mountain Apennine stations that represent the southern edge of its distribution range.

Geology and landforms

The park lies within the sedimentary formations of the northern Apennines. Lower areas between Vidiciatico and Lizzano are associated with the Sestola-Vidiciatico Unit, a heterogeneous complex of marly, calcareous and sandstone rocks formed in a deep marine basin between about 75 and 20 million years ago.

The higher ridges of Corno alle Scale are shaped by the Monte Cervarola Sandstones, deposited between about 23 and 17 million years ago in deep-marine environments. These sandstone layers crop out continuously along the main ridge and form the regular stepped profile from which the mountain takes its name.

Selective erosion has produced ledges, recesses and stepped forms along the slopes. The Balzi dell'Ora are among the clearest examples of this morphology, where sandstone layers are separated by thinner and more erodible levels. The Dardagna waterfalls and the ravine known as Orrido di Tana Malía are linked to the same geological structure, where resistant sandstone layers control the formation of drops, ravines and erosional steps along the upper watercourses.

The Cavone basin, between Corno alle Scale and Monte La Nuda, preserves the most significant glacial landform in the park. Regional sources describe it as a cirque shaped by Würmian glaciers, with steep sides, a gently sloping floor and a weak morainic counter-slope. During the maximum Würmian glacial expansion, about 50,000 years ago, a glacier tongue descended the Dardagna valley as far as the Madonna dell'Acero area, where traces of morainic deposits are still recorded.

The Dardagna waterfalls are one of the most recognizable natural features of the park. They consist of a sequence of drops and pools along the upper Dardagna stream, where the watercourse cuts through alternating sandstone and more erodible layers. From the edge of the highest waterfall to the terminal pool, the stream overcomes a total difference in height of more than .

The park also preserves evidence of Apennine folding. Regional sources describe characteristic overturned anticlines in the sandstone formations, including a well-exposed fold on the left side of the Dardagna valley, visible from the Dardagna waterfalls and from the road to Madonna dell'Acero.

History and cultural landscape

The Corno alle Scale area has historically formed part of a mountain landscape of forests, pastures, passes, religious sites and small settlements. Park sources record prehistoric seasonal presence in the mountains, medieval routes and rural structures linked with traditional Apennine activities.

During the Middle Ages the territory was linked to the Exarchate of Ravenna, the Abbey of Nonantola and later the Comune of Bologna, which used towers and small defensive castles to control the mountain area. The ridge also had historical border significance. After the 1763 settlement between the Este authorities and the Papal States, boundary stones were placed along the ridges; the former Passo della Calanca became known as Passo dei Tre Termini because it marked the meeting point of the Papal States, the Grand Duchy of Tuscany and the Este possessions.

The cultural landscape of the park is closely linked to the historical use and protection of woodland. Between 1293 and 1333 the Senate of Bologna commissioned a canal intended to divert water from the Dardagna towards the Silla and the Reno, in order to support the transport of timber towards Bologna. Park sources identify the name of Poggiolforato as the most tangible surviving evidence of this former work.

In 1495 the Sedici Riformatori of the Senate of Bologna sent a letter to the Massaro del Belvedere requesting that the local woods be maintained and conserved. According to the park authority, the document, preserved in the Archivio di Stato di Bologna, is considered among the earliest Italian records concerning the conservation of woodland.

Religious sites form part of the cultural landscape of the park. The sanctuary of Madonna dell'Acero, near the Dardagna valley, is a sixteenth-century religious site historically located along the route to the high pastures and the Strofinatoio area. Park sources describe it as a place of devotion for shepherds, woodcutters and pilgrims from neighbouring valleys, with numerous ex-votos preserved inside the church.

The eastern sector around Monteacuto delle Alpi and the Rio Baricello valley preserves another aspect of the park's cultural landscape. Park sources record stone-built hamlets, woodland, the sanctuary of Madonna del Faggio, an old mill and chestnut-drying buildings in this part of the protected area.

The area was also affected by the Second World War. On 27 September 1944, German forces killed about thirty civilians at Cà Berna, between Vidiciatico and Madonna dell'Acero, during one of the wartime massacres recorded in the upper Reno valley.

Access and recreation

The park is crossed by marked hiking routes connected with the main Apennine ridge, the Dardagna valley, the Cavone basin, Monte La Nuda and Corno alle Scale. The Alta Via dei Parchi, a long-distance route through the Apennines of Emilia-Romagna, Tuscany and Marche, is linked with the ridge system around Corno alle Scale.

A ski area operates on the slopes of the Corno alle Scale massif, within the municipality of Lizzano in Belvedere. The area is associated with Italian alpine skier Alberto Tomba, who learned to ski there; two runs are named after him.
