Chatsworth Estate in Derbyshire will receive a new wood later this year.
The Woodland Trust, Chatsworth Estate and the Forest Commission are working together to plant the wood which has been organised to mark Her Majesty's 60 years on the throne.
The 'Diamond Wood' will be 62 acres in size, that's equivalent to nearly 42 football pitches.
The Forestry Commission will grant £155,000 to pay for the project that will see 40,000 trees and shrubs planted in moorland in the Chatsworth Estate.
The Duke and Duchess of Devonshire will plant the first trees in November with local school children.
