2025 Texas City Nature Challenge
Welcome to the 2025 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 25 at midnight and runs to midnight Monday, April 28. Then join people until Sunday, May 4 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: www.inaturalist.org/projects/city-nature-challenge-2025-global-project.
For more information about City Nature Challenge, contact our TNT staff at tracker@tpwd.Texas.gov.
With the iNaturalist App, you just take a picture of a plant or animal and the community will help identify what species it is.
Any observation made during the four days of the event in the greater metropolitan area of each city will count towards the challenge.
You can participate by exploring the life in your backyard, in your local park or on a field trip with your local naturalist group.
If you're new to iNaturalist, learn more with the iNaturalist Getting Started Guide.
