2023 City Nature Challenge

Join us in this friendly global effort to safely explore biodiversity from April 28 to May 1, 2023! Please join the project and spread the word to your friends and neighbors. During May 2-7, upload and identify observations. The collective global results will be announced on May 8.

During the four days, just go make observations! They’ll be added automatically (you don’t need to manually add it to the project—in fact, you can’t!).
