Using the iNaturalist App

iNaturalist is an initiative of National Geographic and the California Academy of Sciences, iNaturalist is a network of citizens, naturalists and biologists who map and share observations about biodiversity around the globe. 

The app is free and open to everyone. Members can browse nearby posts, upload their own images and audio recordings, and receive feedback and information from the iNaturalist community. 

To have your observations counted for the Tri-Cities in this year’s City Nature Challenge:

  • Go to iNaturalist or download the free iNaturalist app from the App Store or Google Play and create an account.
  • Under Projects, search for and join “City Nature Challenge 2022: Tri-Cities, British Columbia”.
  • From Apr. 29 to May 2, click Observe on the app or Add Observations on the website to add observations of any wild living or dead organism you see in the Tri-Cities – including plants, animal, birds, fungi, etc. – or evidence of them, such as shells, feathers or scat. 
  • Observations may include descriptions, uploaded photos, or photo or audio recordings through the app. Photos should be clear and full-frame.
