Invasive species impact on German ecosystems

Overview

Invasive species are causing significant ecological disruption across various regions in Germany. Initially, the spread of the North American bullfrog was identified as a major threat to biodiversity, particularly in Baden-Württemberg and Rhineland-Palatinate. These large amphibians compete with native water frogs for territory and consume a wide range of prey, including insects, small mammals, and other amphibians.

Further ecological concerns have emerged in Erfurt and Thuringia regarding other non-native species. The release of pet goldfish into natural waters has led to the decline of native species like the Prussian carp, as goldfish consume smaller fish and amphibian eggs. Officials have noted that goldfish can interbreed with native populations, leading to calls for stricter trade bans. Additionally, the blueband goby and invasive crayfish are impacting local ecosystems; the latter specifically threatens native populations by spreading crayfish plague.
