Theme Trails – The Historical Sonvico Nature Trail
Stage 6: Geological oddities
As we leave this area south of the village centre, characterized by areas of extensive cultivation, we enter the mixed broadleaf woods. The structure of this natural wood consists of four layers of vegetation.
Here we can observe a contact between two kinds of different metamorphic rocks, i.e. rocks that during their forming went through changes due to huge variations in compression and intense heat. The large boulder that appears on the right of the bridge, (of a reddish colour) of untidily compacted paragneiss (Gneiss of Stabbiello), meets hornblende and epidote schist (grey) along the edge of the stream. These metamorphic rocks are very old, going back more than 280 million years (Permian).
In the surrounding wood grow the Sycamore, Wild Lime, Common Ash, Chestnut, and the Locust tree. Behind the emerging rock, grows a Medlar. Due to its humidity and the particular freshness, this is an area rich in ferns. Of special interest among the different species to be found in the dry-wall behind the mill, is the Soft shield-fern. This plant is protected by Federal law and is registered in the "Red List". We also find the Wall rue, the Common Polypody, the Scaly fern, the Male fern, and the Lady fern.
Wild boars regularly visit this area, as can be seen from the many holes in the ground made by these animals when rooting for food: acorns, roots, bulbs, insects, and worms. The wild boars' digging habits are beneficial to the wood's ground. After disappearing from Ticino for more than two centuries the wild boar reappeared in the Malcantone in 1981 and has now repopulated our woods.
