City Nature Challenge Texas
2023 Final Results

Congratulations to all the 2023 City Nature Challenge participating cities and metro areas for another success year of citizen science contribution! More than 6,050 citizen scientists recorded 173,685 observations of 7,647 species (as of June 30, 2023) from El Paso to Houston, Amarillo and Wichita Falls to the Lower Rio Grande Valley. Among those more than 7,000 species were 3,000 observations of 124 Species of Greatest Conservation Need. Below are the results for each metropolitan area as well as a link to each project on iNaturalist.

Take the City Nature Challenge!

Join Texas Parks & Wildlife, Texas Master Naturalists, the Audubon Society, The Nature Conservancy and others in a fun challenge to see which city can document the most species. It is easy to participate by joining an event or making observations on your own using iNaturalist — sign up on iNaturalist.org and download the App for your device: iNaturalist for iOS and iNaturalist for Android.

Once again, this year you can participate in City Nature Challenge even if you don’t live in one of the metro areas. Visit City Nature Challenge 2023 Global Project. Simply click on the link, join the project and you are ready to join the fun.

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.

To find out if your metro area is participating, check the list below and get involved! Not only is this a competition between metropolitan areas across Texas, cities across the world are participating — let's show them what we've got! Be sure to check out the City Nature Challenge Website to see the list of global participants.
