Ashdown Forest

Caroline Leafe, 70, was walking along a deer track in Ashdown Forest with her husband, Kenneth, when the pair were hit by a silver birch tree.

Friends and family are staging a 70-mile walk in Sussex in memory of conservationist James Adler who died suddenly last year.

35 ponies, split into three herds, are being used to graze Ashdown Forest and improve the habitat for rare plants and wildlife.
