The children magazine Panewippchen, edited for the members of the Panda-Club of the Luxembourg National Museum of Natural History, has published an interview with Dr Christian Ries, curator of the Department of Ecology:
The last page of the article suggests the young readers to participate to a citizen science survey concerning the recent spread into the wild of the cherry laurel (PrunuslaurocerasusL.), a common garden plant in Luxembourg, mostly planted to build hedges. Fruits can be dispersed over long distances by birds.
Interested children are asked to look into the forests in their neighbourhood, the evergreen cherry laurel being very easy to spot in winter time, when trees and shrubs rejected their leaves.
The children are asked to send the following basic information to :
How many cherry laurel individuals have been spotted?
Where were they spotted (using GPS of portable devices)
This molecular toolbox will encompass several techniques of detection comprising (1) a simple amplification method easily performed in a laboratory with few elements, (2) a digital droplet amplification (ddPCR) which is a more elaborated lab method that can allow for a higher detection sensitivity and a possible quantification of DNA that could be related through the proxy of biomass and abundance to the size of the populations detected and (3) an isotherm amplification method (iPCR) i.e. a simple, cost effective approach which will allow for a field detection usable by non-trained agents.
The results will enable the development of a predictive species distribution model for the target species and to infer their impact on freshwater communities through the comparison with previous sampling campaigns. This set of methods has the high potential to efficiently contribute to early detection and routine monitoring of the invasive crayfish species in Luxembourg, thus allowing for a timely and efficient decision-making and appropriate management.

In Flanders, Canada goose are causing social, economic and ecological impacts. The population is managed using a combination of methods which requires an adaptive management approach involving multiple actors and stakeholders and monitoring of the population. The lecture will also address the Egyptian goose.

On 19th September 2017, a forester captured a Nutria (Myocastor coypus) 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).
The species was first documented in Luxembourg in 1957 at the Alzette river next to Hunsdorf (Municipality ofLorentzweiler). 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).
