Luc started his search for as many species as possible in his garden on January 1, 2021. Initially the goal was to find a thousand different species, but he has doubled that. The idea arose during the corona crisis when Luc was bored at home. Now he deals with it almost every day and he has also infected the rest of his family. The search area covers his front yard, his balcony and the lawn in front of his house. The air above the home also counts.
