Recently joined @NABU for a walk through Berlin's Wuhletal, which is currently being renaturalized. Beavers and otters - once gone - are back and thriving. Incredible animals and brilliant builders! It's also fascinating to see how the moor frogs and moorhens immediately feel better here as soon as the beavers dam up the water with their structures. A rising water level would also be relevant to climate protection as a sink for peat.
