Cities around the world are working together to share their observations of nature as part of the City Nature Challenge. Participants take photos and upload them to iNaturalist.lu. This helps to expand the databases on Luxembourg’s flora and fauna!

In Luxembourg, the CNC is coordinated by the National Museum of Natural History. A number of events will be organised in Luxembourg by various organisations, including CELL!
