The biggest peat bog in Europe, in Caithness and Sutherland, has become a UNESCO World Heritage site, putting it on a par with Tanzania's Serengeti and the Eiffel Tower. It's the first such designation for a peatland site, and is expected to have an impact on the local economy, boosting tourism and peatland restoration work. What is so interesting and important about this vast wet desert of undulating brown hills in the UK's far north? Is the new tag helping the region, or as some fear, hindering development? Richard Baynes has been talking to those who live and work in the wild natural world of the Flow Country.
