Contribute to Science with the Tri-City Nature Challenge

COQUITLAM, BC, Apr. 12, 2023 The cities of Coquitlam, Port Coquitlam and Port Moody are hosting guided walks, hatchery visits, children’s activities and more for their second year of participation in the City Nature Challenge.

The celebration features 15 events primarily from Apr. 28 to May 1 when residents can document plants, animals and other organisms on the iNaturalist app.

A Tri-City Collaboration

The City Nature Challenge is a friendly global competition that encourages people to find and document wildlife in their cities. The three cities will compete with communities across Canada and around the world to gather the most observations about nature, find the most species and engage the most people from Apr. 28 to May 1 through iNaturalist. All Tri-City residents are encouraged to participate and help contribute even more observations than we did in 2022:

  • 129 people, across 3 municipalities, provided a total of 2,790 observations
  • 2nd highest observer total in participating BC municipalities
  • 3rd highest number of observations in participating BC municipalities

Tri-City Nature Challenge Events

All events are free and open to Tri-City residents, but some activities require pre-registration. Signing up for the iNaturalist app is not required to participate in the events but is required to share your observations and take part in the competition.

Using iNaturalist

An initiative of the National Geographic Society and the California Academy of Sciences, iNaturalist is a network of amateur and professional naturalists who map and share observations about biodiversity around the globe.

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

  • Go to or download the free iNaturalist app from the App Store or Google Play and create an account.
  • From Apr. 28 to May 1, head out in to nature to find wildlife in the Tri-Cities, including plants, animal, birds, fungi, etc. – or evidence of them, such as shells, feathers or scat
  • How to record your observations: Hit Observe on the app or Add Observations on the website to add or upload your photos, audio recordings or descriptions. Photos should be clear and full-frame.

Visit the City Nature Challenge FAQ webpage at for detailed instructions and tips for making eligible observations.

Observe and Protect our Wildlife

  • Be safe and give animals their space – sometimes a memory is better than a picture, give bears, cougars and coyotes at least 100m of space and leave the area quickly and calmly.
  • Walk on designated trails and stay on the trail to protect wildlife habitat.
  • Do not touch or pick up live animals or plants. Use your eyes and ears, and your phone, to make observations of species in their natural habitat.
  • Leave No Trace: take care to leave no litter and not to damage the habitats you are enjoying. Even fruit peels and cores can cause damage to sensitive places or put animals at risk.
