What happens when you build a piece of nature that has no historical precedent?
Marker Wadden is the most natural artificial place I’ve ever visited. Or is it the other way round? Either way, this bleak archipelago is a beguiling and intriguing place, built with silt from from the lake floor, in a freshwater surrounding where there used to be a marine one. It was fascinating to hear the problems involved in building it — and the problems involved encouraging it to flourish now. Marker Wadden touches on almost every issue in restoration, rewilding and conservation.
