Historical management
Although the Atlantic hazelwoods would historically have been exploited by people, it is thought that the exploitation was limited to seasonal sheltered grazing of livestock and the selective cutting of hazel poles, with

Two discrete communities of lichens grow on Atlantic hazel. Young, smooth-barked hazel stems are colonised by crustose lichens of the Graphidion, including the very rare Graphis alboscripta.][ Old, rough-barked stems are colonised by leafy lichens of the Lobarion; a community that is very rare and declining in Europe.][
Atlantic hazelwood is also the habitat of the rare fungus hazel gloves (''Hypocreopsis rhododendri'').][
