City Nature Challenge

The City Nature Challenge (CNC) is an annual event where Coquitlam competes with communities around the world to gather the most observations about nature, find the most species and engage the most people using iNaturalist, a project of National Geographic and the California Academy of Sciences.

2023 Tri-City Nature Challenge  

We joined Port Coquitlam and Port Moody for our second year and hosting guided walks, hatchery visits, children’s activities and more.  

Across the three cities there were 15 events when residents can document plants, animals and other organisms on the iNaturalist app. Thank you to everyone who participated! 

  • Total observations: 1,434
  • Total species observed:  363


Please check out this 1-hour webinar with Canadian Wildlife Federation's, James Pagé,  explaining this annual global event. 

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. 
  • Observations may include descriptions, uploaded photos, or photo or audio recordings through the app. Photos should be clear and full-frame.
