City Nature Challenge

Photographing nature with phone

April 30 - May 3

The City Nature Challenge (CNC) is the largest citizen science event that uses iNaturalist and will happen April 30-May 3, 2021. This event is particularly unique because of the emphasis placed on documenting urban biodiversity. Now in its sixth year, this global event will have more than 325 cities participating and is organized by the Natural History Museum of Los Angeles and California Academy of Sciences. Among these are 23 Canadian cities including five areas within Alberta (Calgary Metropolitan Region, Edmonton Metropolitan Region, Camrose County, Red Deer/ Lacombe County, and Lethbridge). These areas will compete to see which urban area can make the most observations, document the greatest number of species, and engage the most people. Take photos anywhere within the boundaries and share them to They will automatically be included in your local CNC project! Even if you live outside of these areas, you can still be involved by helping to identify observations shared. Visit to view the Canadian Wildlife Federation’s CNC 2021 Canada project and see how Canadian cities’ biodiversity stacks up to one another.
