Wistman's Wood, Devon, England

We’re on Dartmoor in Devon, where the twisted oak branches of Wistman’s Wood shelter some of the rarest plant life found in the United Kingdom. This ancient site is one of Britain’s highest oakwoods and is an example of a temperate rainforest, a rare habitat found along the Atlantic coastline. The mild and damp conditions here make it ideal for a number of scarce lichen, mosses and fungi. The wood is home to Horsehair lichen (Bryoria smithii) found at only two sites in Britain.
