Peene

Peene. The Peene is a river in the German state of Mecklenburg-Vorpommern, often referred to as "Germany's Amazon" due to its extensive, pristine lowland wetlands. It flows for approximately 136.5 kilometers from its source near Gnoien to its mouth into the Peenestrom, a strait connecting to the Baltic Sea. The river's catchment area forms the central part of the larger Peene Valley region, a landscape of significant ecological importance within Central Europe.

Geography and course

The Peene originates from a confluence of drainage ditches in the Mecklenburg Lake District plains southwest of Gnoien. Its initial course runs westward before turning north near Demmin, where it is joined by the Tollense and Trebel rivers, forming a unified flow often called the "Three Rivers City." From Demmin, the Peene flows predominantly eastward through a wide, glacial urstromtal valley, passing towns such as Loitz, Jarmen, and Gützkow. The final segment of the river widens considerably into a brackish estuary before merging with the Kleine Peene and Swine to form the Peenestrom, which separates the island of Usedom from the mainland. This entire lowland region, characterized by fens, floodplain forests, and oxbow lakes, lies within the West Pomeranian Lagoon Area National Park.

History

The Peene Valley has been a significant cultural and political borderland since early medieval times, marking the western frontier of the Slavic settlement area later known as Pomerania. During the Middle Ages, control over the river was contested between the Duchy of Mecklenburg and the Duchy of Pomerania, with fortifications established at Demmin and Loitz. The Treaty of Kremmen in 1236 cemented Pomeranian control over the region. In the 17th century, the river gained strategic military importance during the Thirty Years' War and the Scanian War, with notable actions like the Crossing of the Peene by Brandenburg forces. The Congress of Vienna in 1815 assigned the entire Peene region to the Kingdom of Prussia. In the 20th century, the area saw limited action during World War II before becoming part of the German Democratic Republic, after which its ecological value began to be formally recognized and protected.

Economy and navigation

Historically, the Peene was an important transport route for goods like timber, grain, and peat, connecting the agricultural hinterland to ports on the Baltic Sea. Towns such as Anklam and Demmin developed as trading hubs. While commercial shipping has greatly declined, the river is now a major destination for water tourism, including canoeing, yachting, and river cruises on historic vessels like the MS *Königin Luise*. The federal waterway, managed by the Wasserstraßen- und Schifffahrtsamt Ostsee, is maintained for recreational and small craft use up to Demmin. The region's economy also benefits from sustainable practices such as fishing, particularly for pike and zander, and low-intensity agriculture that supports the preservation of the cultural landscape.

Ecology and environment

The Peene Valley is one of the largest contiguous fen landscapes in Central Europe and a cornerstone of the European Green Belt. Its extensive floodplains, reed beds, and alder forests provide a critical habitat for numerous rare species, including the European otter, European beaver, white-tailed eagle, and black stork. The river's hydrology is largely natural, with minimal canalization, allowing for seasonal flooding that maintains the wetland ecosystem. A large portion of the valley is protected under the Natura 2000 network and as part of the Peene Valley Nature Park. Major conservation projects, often involving organizations like the Michael Succow Foundation, focus on rewetting former drained areas to preserve biodiversity and function as a significant carbon sink.

Tributaries and hydrology

The most significant tributaries are the Tollense and the Trebel, which converge with the Peene at Demmin. Other important left-bank tributaries include the Südpeene and the Kleine Peene, while the right bank receives the Krienker Bach and the Schwinge. The river's flow is characterized by a very low gradient, averaging only about 10 centimeters per kilometer, which contributes to its slow, meandering nature and the formation of extensive backwaters. The hydrological regime is influenced by the Baltic Sea, with water levels in the lower estuary affected by wind setup and seasonal variations in the Peenestrom. The entire catchment area drains into the Szczecin Lagoon before reaching the open Baltic Sea.
