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 29 - May 2. 

Last year, San Antonio logged almost 15,000 observations!

It is easy to participate by joining an event or making observations on your own using the iNaturalist app. With the iNaturalist app, you 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 San Antonio will count during the four-day challenge. You can participate by exploring life in your backyard or in your local park.

Make your mark in citizen science with this self-led activity. All you have to do is go for a walk in the park & submit images during this Bio-Blitz window! Phil Hardberger Park has tons of wildlife to log!

For anyone interested in science, data, and wildlife tracking. This is an independent, Self-Led Activity
