Texas City Nature Challenge
April 26 to 29, 2019

Take the City Nature Challenge!

Join Texas Parks & Wildlife, Texas Master Naturalists, the Audubon Society, 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.


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.


Not only is this a competition between eight metro areas in Texas, cities across the world are participating — let's show them what we got! Find local partners and events on the City Nature Challenge 2019 Texas Events webpage, and check out the City Nature Challenge Website to see all cities participating across the globe.


For questions or more information, or if you'd like to become a local partner, contact our Texas Nature Tracker biologists at tracker@tpwd.texas.gov. To learn more about Texas Master Naturalists, see the Texas Master Naturalist website.
