Overview

• Experts say many established species such as raccoon, signal crayfish and Asian tiger mosquito are unlikely to be eradicated in Bavaria.
• Health officials in Erlangen deploy traps to track the Asian tiger mosquito, while beewarned.de coordinates responses to the Asian hornet.
• About 630 sizable stands of allergenic ragweed were reported across Bavaria from 2007 to 2023, with clusters in Upper Bavaria, Middle Franconia and parts of Lower Bavaria.
• The North American signal crayfish displaces native crayfish and carries a lethal fungus, and once established it cannot be removed according to the state environment agency.
• Authorities urge the public not to feed raccoons or geese, to clean aquaria responsibly, and to avoid returning invasive fish bycatch, as globalization and warming drive new arrivals.
