City Nature Challenge

This spring, Chandler Parks & Recreation invites you to get outside and discover what’s living in your backyard, park, or nearby natural area while also helping the scientific community. Held from April 29 to May 2, City Nature Challenge is a four-day, global bio blitz, where cities from around the world compete to see who can make the most observations of nature, find the most species, and engage the most people.

Chandler is one of four organizations hosting the Greater Phoenix Area City Nature Challenge encouraging the community to look at nature, take photos, and put them in the iNaturalist app to document all they can find.


April 29 - May 2     Observation Days

Download the iNaturalist app onto your smartphone. Once you download the app, you can use it right away, year-round. But you’re encouraged to save most of your observations for the April 29 – May 2 City Nature Challenge to help Chandler rise in the ranks!

  • Tip: You can take a photo or video on your phone and upload it to the iNaturalist app later or even use recently taken photos.
  • Find any wild thing. It can be any wild plant, animal, fungi, or any other evidence of life (fur, tracks, shells, scat, etc.) found in Chandler – including your own backyard.
  • Tip: If you have outdoor space at home, take a closer look. Is there moss growing in the cracks of your patio? Are there moths that visit your outdoor lamp at night? These all count in the City Nature Challenge!
  • Tip: Participate during your walk or run in the park. If you’re outside getting some exercise, keep an eye out for flora and fauna along the way.
  • Tip: Be sure to tag. Use the hashtag #ChandlerNatureChallenge on social media to share how you’re participating in this year’s event.
  • Take pictures or videos of what you find using the iNaturalist app.
  • Learn more as your observations get identified. All you have to do is snap a photo – a professional will help you identify your observation through the app!

Chandler Nature Center will be hosting two open house days in April – which coincidently is Citizen Science Monthfor the community to learn more about citizen science, how to participate in the Challenge, and connect the iNaturalist app to their personal device.
