Britain’s youngest national park is edging closer towards planting 100,000 trees by its 15th anniversary next year as it begins its “major nature recovery drive” this winter.

National park countryside and policy manager Nick Heasman said: “Trees provide clean air for us to breathe, enrich our soils, provide a vital habitat for wildlife and, crucially, are amazing carbon capturers.
