Description
YEW SILVER FIR are particularly rare, occurring only in small and fragmented sub-sites located in areas where the rough terrain spared them from the intensive logging of the past. The Apennine populations of these conifers are probably sub-species differentiated from each other and distinct from the corresponding populations in the Alps. They are threatened by a preponderance of old trees and a low rate of rejuvenation. These ecological constraints are worsened by the effects of livestock, which have succeeded in completely killing off rejuvenation. Additionally, the sylvicultural practice of coppicing – that benefits trees that grow and multiply by sprouting offshoots (suckers) – has had serious consequences for the less competitive spruces and firs.
