Nutrias in Northern Germany - How Dangerous Are These Rodents? - Invasive Coypu Overrun Northern Germany, Forcing Massive Hunter-Led Culls

Coypu, also known as nutria or swamp beavers, are rapidly spreading across northern Germany, posing a significant threat to local ecosystems, infrastructure, and agriculture. Authorities have intensified hunting efforts to control their numbers and mitigate the damage they cause.

Originally from South America, coypu were introduced to Europe for fur farming. Over time, they escaped or were released, establishing wild populations. Now, they thrive in northern Germany, including Hamburg, Bremen, and rural regions like Lower Saxony.

These rodents inhabit waterways, nesting in reeds or digging burrows into riverbanks. They primarily feed on aquatic plants, foraging at dusk and throughout the night. Their constant gnawing and tunneling weaken dikes, drainage channels, and riverbanks, increasing flood risks and damaging water management systems.

The ecological impact is severe. Coypu destroy habitats for native wildlife by overgrazing vegetation and altering ecosystems. In Lower Saxony alone, hunters killed nearly 54,000 of them in the 2024/2025 season to curb their spread.

While no German state has officially introduced nutria meat into trade or restaurants, some hunters in Schleswig-Holstein use the meat informally. They prepare it as stews or burgers, though no formal gastronomic initiatives exist yet.

Hunting remains the primary method to control coypu populations and protect native species. Their rapid reproduction and destructive habits continue to pose risks to infrastructure and local ecosystems. Authorities will likely maintain culling efforts to reduce economic and environmental harm in affected regions.
