Triangolo lariano is also the name of a Special Protection Area (593 hectares) protected by European laws, located in the Corni di Canzo (Horns of Canzo). Its protection concerns 84 precious bird species (including the honey buzzard, the peregrine falcon, the rock partridge, the eagle owl, the nightjar, the tawny pipit, the red-backed shrike, and the ortolan bunting) and the habitats, e.g. the natural dry grasslands and scrubland facies on calcareous substrates (Festuco-Brometalia) —- with significant blossoming of orchids—the limestone pavements and the petrifying springs with tufa formation (Cratoneurion), and the calcareous beech forests of Central Europe Cephalanthero-Fagion. Inside is another nature reserve, the Site of Community Importance Sasso Malascarpa (328 hectares), with 52 protected species, among which are the greater horseshoe bat, various kinds of backed shrike, and the rare white-clawed crayfish. A peculiar habitat of the reserve consists in the stone springs with travertine formation. The alternation of woods, meadows-pastures, and rock formations in the mountains of Canzo, makes the landscape particularly popular for tourism.
