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 30 - May 3. 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 Dallas/Fort Worth 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!
