Trees were worshiped all around ancient Europe in different ways. The Yew tree is often found in churchyards and graveyards in England because pagan religious sites were chosen as ideal locations for churches at the time of conversion. Yews were probably sacred to both the Celts and Anglo-Saxons but in Germanic paganism the Ash and the Oak were more important. The Anglo Saxons had a rune for the Yew tree and another for the Ash. This video looks at the Yew tree rune Ēoh.
In Baltic paganism the English Oak was also very important. The Stelmužės ąžuolas (Stelmuze oak) in Lithuania is about 2000 years old and was sacred to the thunder god Perkunas. The oak tree was associated the equivalent god Thunor / Donnar / Thor by Germanic peoples because it is struck by lightning more frequently than other trees.
All Indo-European peoples recognize that tress are sacred and venerate and protect ancient and sacred trees.
