This year the popular Citizen Science Campaign City Nature Challenge will again take place – from April 30th to May 3rd, 2021. Cities and urban regions can register for the international biodiversity event and compete against each other in order to observe and document as many species of animals, plants or fungi as possible.

Last year, more than 800,000 wild species were reported in over 240 cities around the world. Austria participated for the first time in 2020 with the regions Vienna, Graz and Krems/Wachau.
It is very pleasing that significantly more Austrian regions have registered this year:

Everybody can participate!

Species can be reported during the 4 days in the regions specified above. Simply install the iNaturalist app and create a free account, take a photo of the animal or plant – upload it and add the determination as far as possible. It is important that the species found are correctly identified – many experts take part in this and will add the correct species name of the depicted organisms. All experts are invited to participate in the determination process!
