Join Texas Parks and Wildlife, Texas Master Naturalists, the Nature Conservancy, the Audubon Society, and many others in a fun challenge to see which city can document the most species during April 24 - 27. 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 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. You can also help with IDs for other people's observations to increase our species count, come to a bioblitz, or even hold your own event!
