For the first time ever, the entire Greater Vancouver area is joining the City Nature Challenge! You can contribute to community/citizen science during this global biodiversity challenge no matter where you are, from downtown Vancouver, to paddling the Pitt-Addington Marsh, to exploring the beaches of White Rock! Observations collected during this period are used for monitoring biodiversity and ecological research.

From April 29th – May 2nd, simply use iNaturalist to make observations anywhere around the region, and they’ll be added to this project!

All you need to do is:
• Download iNaturalist (links below)
• Make an observation of a wild animal, plant or fungus from April 29th – May 2nd.

Observations can be uploaded directly through your phone, or uploaded on your computer through May 8th.
• Follow the project on iNaturalist (links below) to see the results roll in!

On this page, you will find links to the iNaturalist project, as well as links to download the app. Below that you can view our quick start guide with resources on iNaturalist, identifying species and citizen science in general. Below that you will see our calendar of events, and at the bottom links to the other City Nature Challenge projects around BC!

Reynolds will teach you how to use iNaturalist, explain iNaturalist’s role in conservation, and answer your questions.


Join one of our volunteer naturalists on a free guided walk as they help you discover the unique ecology of each park and make observations on iNaturalist, to submit to the City Nature Challenge.

  • A device with the iNaturalist app already downloaded. Observations can be uploaded immediately using data, or uploaded later using a WiFi connection.
