Helen Mark visits the National Forest as its marks 25 years since it started to create huge areas of woodland.

The entire area covers 200 square miles across the boundary of the East and West Midlands over the three counties of Derbyshire, Staffordshire and Leicestershire. Helen explores how this regeneration through nature has impacted upon the lives of the people in the area.

She begins by planting our very own 'Open Country' oak tree.
