The Wildlife Trusts have bought part of the Duke of Northumberland’s son’s estate in the largest land sale in England for 30 years.

Marketed by its estate agents as “a paradise for those with a penchant for sporting pursuits, from world-class fishing on the illustrious River Coquet to pheasant and grouse shooting”, Rothbury estate has now been bought by the federation of charities, which plans to restore it for nature.

The Wildlife Trusts are buying the land in an unusual two-phase deal: having already bought a “significant” chunk of the 3,850-hectare (9,500-acre) estate, they have been given two years to find the rest of the money, for which they are launching a fundraising appeal. The estate was previously used for intensive sheep farming and shooting.
