City Nature Challenge: Use iNaturalist near you!

Welcome to the 2026 City Nature Challenge. Once again, Texas Nature Trackers (TNT) is proud to help sponsor this statewide community event that encourages everyone to get outside, explore the natural world around them and document local flora and fauna using iNaturalist. Not only is iNaturalist a great tool for self-learning about the natural world, your observations contribute to greater understanding of the state’s plant- and animal-life.

This year’s event kicks off on Friday, April 24 at midnight and runs to midnight Monday, April 27. Then join people until Sunday, May 10 to continue uploading observations you made during the four-day period and help others to identify what they found.

Take a look below to find out if your metropolitan area is participating this year and make plans to join the fun! Even if you don’t live in any of those areas, you can still participate by joining the global challenge at City Nature Challenge 2026 Global Project.
