On Tuesday 7th August 2018 from 18:30 to 20:00, in the frame of its Science Tuesdays series, the National Museum of Natural History organised a scientific walk through the Grund district. Dr Christian Ries, curator of the Department of Ecology, gave explanations about a dozen invasive alien species to the 20 people in attendance. In its edition of 9th August 2018, the Luxembourg Newspaper Journal published a small article about the event.
