2025 City Nature Challenge
April 25 - April 28
The Houston-Galveston area participating in the 2025 City Nature Challenge includes Austin, Harris, Brazoria, Liberty, Chambers, Montgomery, Fort Bend, Waller, and Galveston counties. Observations for the challenge should be made within this 9-county area.
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.
For more information about City Nature Challenge, contact our TNT staff at tracker@tpwd.Texas.gov.
