Cfr. note¹ over the above image.
Picea abies is spontaneous in IT only in the alps and in 2 locations of northern appennines (Passo del Cerreto and Alta Valle del Sestaione) where its southern limit of distribution dates back to LGP. Campolino Natural Reserve, 2 km from the botanical garden, hosts a native P. abies woodland. Fossil pollen found in the peat bog of Greppo lake dates back to 21-10 kya. At that time many northern spp pushed southwards; when climate changed again, many of them became extinct in the newly colonized territories, remaining only in limited areas in relictual conditions.
