City Nature Challenge Texas

Austin vs. Houston vs. DFW

April 14-18, 2017

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 the iNaturalist app.

With the iNaturalist app, you just take a picture of a plant or animal, and the community will help identify which species it is.
Any observation in the greater metropolitan area of each city will count during the five day 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 Dallas/Fort Worth, Austin, and Houston, cities across the nation are participating, let’s show them what we got!

Check out the national City Nature Challenge Website to see all cities participating across the country.
