The Oder Delta is an important river catchment in the borderlands of Poland and Germany. Here, intricate waterways meander through hay meadows, alluvial forest, marshlands and lagoon, before heading out to the Baltic Sea. This landscape feels rich in life, but it could still be so much more. Pollution events have killed off huge quantities of fish and many of the waterways have been manipulated for milling, agriculture, hydro schemes and transport. Rewilding work is now focused on returning the rivers to a more natural state, and with it, the diverse bounty of life that rely on them.
