This summer the British Lichen Society sponsored a Summer Student project in collaboration with the Royal Horticultural Society. This has produced designs for lichen interpretation boards for the RHS garden in Devon: Rosemoor.
The boards are linked by a trail that can be accessed by downloading a pdf map or through the IZI.travel app. The app provides audio directions around the trail and additional information for many of the stops.
The trail should be ready for its first explorers this winter. Do look out for it if you visit Rosemoor near Torrington next year.
