City Nature Challenge

Join the City of Austin Parks and Recreation Department, Texas Parks and Wildlife, Texas Master Naturalist, The Nature Conservancy, Travis Audubon, and many others in a fun global challenge to see which city can use iNaturalist to document the most species April 28 through May 1. 

On Saturday, April 29 from 9 a.m. to 12 p.m., Austin Parks and Recreation will host a bioblitz event at Red Bluff Nature Preserve, 5808 Harold Ct. Come take photos and document the local ecosystem! You can also help with IDs for other people's observations to increase our species count.

With the iNaturalist app, simply 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 Austin will count during the four-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. 

The City Nature Challenge is organized by Natural History Museum of Los Angeles County and California Academy of Sciences. For more information about the City Nature Challenge visit
