Importance and distribution in Luxembourg
Myocastor coypus was first documented in Luxembourg in February 1954 near the Alzette river in Hunsdorf, Municipality of Lorentzweiler (Heuertz 1957: 50). Currently, it is only observed sporadically in Luxembourg. Because of its occurrence in the bordering regions of France (Chiers, Moselle) and Germany (Saar), it is likely that the species will populate national watercourses within the near future (Becker-Krüll & Schaefer 2013).
On 19th September 2017, a forester captured a coypu in Osweiler (commune of Rosport, eastern Luxembourg) and put it to sleep. This detection of an IAS of Union concern (Anonymous 2016) has been notified by the Luxembourg authorities on 26 September 2017 and an Eradication Measure Set has been submitted as well on 26 September 2017, pursuant to Article 17(1) of R. 1143/2014 (Anonymous 2014).
Overgrazing by coypus can cause local extinctions of aquatic plants, the destruction of reedbeds and of fish nursery areas. Due to its burrowing activity, the species degrades river banks and affects river flow. Rare marshbirds are affected by nest destruction, egg predation or habitat destruction. The coypu could also act as a reservoir of different pathologies and causes damages to agriculture. Coypus are 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.
