Nutria Population Surge Threatens Germany's Flood Defenses and Biodiversity

Nutrias, non-native rodents from South America, pose significant threats to flood protection and biodiversity in Germany. Their tunneling behavior compromises the stability of riverbanks and dikes, raising concerns among environmental authorities.

The German Hunting Association has reported a doubling of nutria populations since 2015, prompting calls for control measures. These animals not only endanger flood defenses but also disrupt the habitats of native species through their feeding habits.

The Federal Agency for Nature Conservation advocates for the cessation of intentional feeding to curb their spread. In regions like Niedersachsen and Sachsen-Anhalt, nutrias have become particularly prevalent, with over half of hunting areas reporting their presence.

Addressing this issue is crucial for maintaining ecological balance and protecting flood defenses.
