The yews represent the 42 dioceses of the Church of England.
We Love Yew is part of the Magna Carta 800th anniversary celebrations and aims to encourage communities to discover their local heritage. The Magna Carta was sealed under the yew at Ankerwycke. The new campaign also aims to support the management and protection of our ancient and veteran yews.
Salisbury Cathedral owns the finest preserved of the four surviving 1215 Magna Carta documents.
David Shreeve, director of the Conservation Foundation, said: "Yews make very few demands, but do need a little bit of TLC from time to time. They can be older than the church where they are near, but often have very little official protection. They are already visited by large numbers of enthusiasts, but we hope this new project will encourage people to learn about their local yew and its place in the history of where they live and ensure they continue to grow for hundreds - possibly thousands more years."
The Conservation Foundation is offering yews for communities to plant.
