Join the Faculty of Environmental Sciences at CZU and become part of the global City Nature Challenge! During this event, we will join forces with people around the world to document urban biodiversity. The goal of the event is to raise awareness of urban nature and support environmental protection through citizen science.This year, you can take part from April 24 to 27, 2026. All you need to do is download the free iNaturalist app to your smartphone and start taking photos of the nature around you.
More information on how to get involved can be found here: https://www.citynaturechallenge.cz/en/about-the-project/
From April 21 to 23, you can also visit our information booth in front of the CZU Rectorate building, where you can learn how to contribute to the understanding and protection of urban nature.
Every observation counts – we look forward to your participation and shared discoveries.
