Thank You!

We wanted to take this opportunity to thank our city organizers, participants and identifiers who have made the 2021 City Nature Challenge a success in Canada. The City Nature Challenge was a great springtime event for people to connect to nature and contribute to scientific research at the same time.

By continuing to upload observations to iNaturalist.ca all year long, you continue to provide invaluable information to track Canada's biodiversity and influence conservation in Canada. The City Nature Challenge would not be possible without the support of people like you!
