Valli del Cedra e del Parma

Valli del Cedra e del Parma Regional Natural Park, also known as the Parco dei Cento Laghi (Hundred Lakes Park), protects approximately 1,472 hectares of Apennine landscape along the upper valleys of the Cedra and Parma rivers in the province of Parma. ^[1] Established in 1995 under regional law n.46/1995, the park encompasses a transition zone where the northern Apennine ridge drops toward the Po Plain, featuring diverse forests, mountain meadows, streams, and small lakes. ^[2] The park connects ecologically with the larger Tuscan-Emilian Apennine National Park along the watershed crest, and its boundaries were reconfigured after the national park's establishment in 2001 and again in 2019.

The park's Apennine forests and meadows support diverse fauna typical of the northern Apennines. Wolves have recolonized the area as part of their broader Apennine recovery, while wild boar are abundant. Roe deer inhabit the woodlands, and the rare wild cat has been documented. ^[1] Golden eagles are occasionally observed, while more common raptors include buzzards, goshawks, and sparrowhawks. The streams support native brown trout and crayfish populations. Fire salamanders inhabit the moist forests, and numerous amphibian species breed in mountain pools and streams.

The park spans an elevation range of 400 to 1,650 meters supporting diverse forest types. ^[1] Beech dominates above 1,000 meters, forming pure stands on the upper slopes near the Apennine crest. Mixed forests of turkey oak, sweet chestnut, and hop hornbeam occupy mid-elevations, including ancient chestnut groves. Riparian zones along the Cedra and Parma streams feature willows, alders, and ash. Mountain hay meadows maintained by traditional mowing support rich wildflower communities including orchids, gentians, and various legumes. Rare endemics include the Apennine primrose. The understorey hosts cyclamens, hellebores, and diverse fern communities.

The park is underlain by the complex geology of the northern Apennine fold-and-thrust belt, with sedimentary rocks including sandstones (Macigno formation), marls, and clay-rich units (Argille Scagliose) representing ancient deep-sea sediments scraped from the ocean floor during mountain building. ^[1] Landslides are common on the clay-rich formations, creating a characteristic hummocky terrain. Glacial cirques and moraines on the highest slopes record Pleistocene ice activity. The Cedra and Parma streams have carved narrow valleys through the varied rock types.

The park experiences a transitional climate between Mediterranean and continental influences typical of the northern Apennines. Temperatures at mid-elevations average around 2 degrees Celsius in January and 20 degrees in July. Annual precipitation is relatively high, ranging from 1,200 to 2,000 millimeters, with peaks in autumn and spring. Snow covers the higher elevations from December through March. Summer is the driest season but rarely experiences true drought. Fog from the Po Plain can penetrate the lower valleys in autumn and winter.

The upper Parma and Cedra valleys have been inhabited since prehistoric times, with pastoral communities exploiting the mountain meadows for grazing. Roman roads crossed the Apennine passes connecting the Po Plain with Tuscany. Medieval monasteries and castles controlled strategic points in the valleys. Traditional land use centered on chestnut cultivation, hay meadow management, and livestock grazing created the diverse landscape mosaic. Rural depopulation in the 20th century led to forest expansion on former agricultural land, changing the landscape character.

Valli del Cedra e del Parma Regional Natural Park was established by Emilia-Romagna's regional government in 1995 under regional law n.46/1995, protecting an area already recognized for its landscape and ecological value. ^[1] The park complements the adjacent Tuscan-Emilian Apennine National Park (established 2001) on the watershed crest, and its territory was reconfigured in 2004 and 2019 as boundaries were adjusted around the national park. Management balances ecological conservation with support for the remaining mountain farming communities whose traditional practices contribute to landscape diversity.

Hiking trails connect the park with the Tuscan-Emilian Apennine ridge and its panoramic crest paths. Notable lakes within the park territory include Lago Santo, Lago Ballano, Lago Verde, and Lago Squincio -- the many small lakes that give the park its popular name of Cento Laghi. ^[1] Mountain meadows are spectacular with wildflowers in June. The traditional stone-built villages of the upper valleys preserve architectural heritage and local gastronomy, particularly Parmigiano-Reggiano cheese produced from local dairies. Mushroom foraging in autumn attracts many visitors to the beech and chestnut forests. Cross-country skiing trails operate in winter when snow cover permits.

The park is accessible from Parma (approximately 50 km) via roads leading into the Apennine valleys. The nearest airports are Parma (approximately 55 km) and Bologna (approximately 115 km). Information points in valley towns provide trail maps and local guidance. Accommodation includes agriturismos, mountain refuges, and small hotels in the surrounding villages. The park's connection to the Apennine ridge trail system enables longer multi-day hiking routes into the adjacent national park.

Conservation priorities include supporting continued traditional mountain farming to maintain habitat diversity, managing forest succession on abandoned agricultural land, and protecting stream habitats from water abstraction. Wolf conservation requires coordination with livestock farmers through damage prevention and compensation programs. The park promotes traditional Parmigiano-Reggiano production, which depends on diverse mountain meadow hay, as an economic incentive for maintaining the landscape mosaic. ^[1] Invasive species management targets exotic plants threatening native communities.
