Mar Lodge Estate in the heart of the Cairngorms has Caledonian woodlands, subarctic mountains, bogs and moorland, burns and lochs, but when the National Trust for Scotland took it over in 1995 the Caledonian pinewoods were dying, the result of a destructive pattern of land use going back over centuries. Now, more than 25 years on, the landscape is regenerating and coming fully alive again. Andrew Painting, Conservation Officer at the estate since 2016 and author of a recent book, tells the story of a remarkable transformation, of the people quietly working away to help to make it happen and the many wild creatures which have inspired them. And generally, he says, if we help nature to heal, it will give back tenfold in limiting, and indeed even reversing, the impacts of climate change.
