The Mount Etna, recently designated as a UNESCO World Heritage Site, is Europe’s biggest and most active volcano. It features beautiful landscapes, important and unique ecosystems, various lava streams, and adventitious crater hills, like the Mt. Egitto, on the west side of the Etna and about 1600 m above sea level. The Mt. Egitto is covered by an old forest, dominated by 56 impressive big oak trees (Quercus pubescens), which are more than 500 years old. But half of the population was in imminent danger of becoming overshadowed by fairly recently planted pine trees. Those damaging pine trees urgently needed to be cut down in order to save the majestic veteran oak trees and the biodiversity of the oak dominated wood.
