Lakes and tarns formed after the Ice Age, river courses and moors, extensive forests, fields and meadows characterise the Uckermark. In the north-east of Brandenburg, 80 kilometres from Berlin and in the immediate vicinity of Mecklenburg-Western Pomerania and Poland, the Uckermark is Germany's largest district, covering more than 3,000 square kilometres. The Uckermark is home to a particularly large number of rare animal and plant species.
