More informationGeorge McGavin investigates the dramatic life of the oak tree - a species that makes extraordinary transformations as it meets the challenges of the four seasons.
In autumn, George goes underground, digging below a tree to see how its roots extract precious resource form the soil. He sees why the oak's super-strong wood made it the perfect material for building some of the most famous ships in naval history, including Nelson's flagship, HMS Victory.
