Texas City Nature Challenge
2025 Results
Congratulations to all the 2025 City Nature Challenge participating cities and metro areas for another success year of citizen science contribution! More than 9,709 citizen scientists recorded 345,000 observations of 9,709 species (as of August 1, 2025) from El Paso to Houston, Amarillo and Wichita Falls to the Lower Rio Grande Valley. Among those more than 9,000 species were 2,262 observations of 122 Species of Greatest Conservation Need. Below are the results for each metropolitan area as well as a link to each project on iNaturalist.
Thank you to all the metro areas and participants for helping to document biodiversity in our state. Also, thank you to Craig Hensley (retired TPWD TNT biologist) and Seth Faught (TNT intern) for helping make the 2025 City Nature Challenge happen.
Interested in participating next year either individually or to help organize an event in your community? First, put the dates of Friday, April 24 to Monday, April 27, 2026 for next year's event. Next, you can register on the City Nauture Challenge website. Organizer meetings will begin December 2025.
Please contact TNT staff at Tracker@tpwd.Texas.gov for information about our efforts across Texas and for help getting your city involved in 2026. We hope to see you and your city as a participant in 2026.
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.
