Importance and distribution in Luxembourg

To date, there is no documentation of the species in Luxembourg.

The American Bullfrog inhabits slow running waters, permanent ponds and ditches with dense vegetation. In Belgium, it is often found in fish ponds. The introduction of the bullfrog outside its native range poses a threat to amphibian populations around the world. The frog negatively affects native amphibians through competition and predation (namely green frog populations). It also preys on many other species, including arthropods, molluscs, fish and birds (eggs and young). Its tadpoles contribute to the species’ negative impact on native biodiversity. Moreover, the bullfrog is frequently reported to be a healthy carrier of the fungus Batrachochytrium dendrobatidis, an emergent infectious disease that is highly virulent, has low host specificity and has been implicated in numerous species extinctions and global amphibian declines. The species is included in the appendix to the recommendation no 77 of the Council of Europe as a species which has proved to be a threat to biological diversity and for which eradication is strongly recommended (Source:
