a forest which is being created in an area of 200 square miles/520 square kilometres in central England, across Leicestershire, Derbyshire and Staffordshire. The project, which is managed by the National Forest Company, was started in 1990 to encourage planting of more trees so that one third of the area, much of which was used in the past for mining, will be covered by trees. The National Forest links several ancient forests. The aim of the project is to plant around 20 million trees.
