Schlagwort-Archive: old growth forests

***Sclerophora peronella***.This species of only a few millimeters in size is extremely rare in Europe and can only be found in larger protected areas (e.g. National Park Bavarian Forest) or in old, near-natural managed forests with a long continuity of ecological processes. It grows in bark scissures of decaying broadleaved trees (beech, sycamore maple). This lichen is threatened globally and in Germany close to becoming extinct (red listed species). Photo ©L.
