City Nature Challenge Bioblitz & Blacklight Event
Sat, April 26, 2025
Join Jane Weeden, City Nature Challenge Bexar County Coordinator, and her volunteer team on a stroll in the canyon followed by an insect blacklighting event.
The program will begin with a short overview on identifying and documenting species using the iNaturalist app. The group will then head onto the Discovery Trail to identify as many species as possible. Afterwards, blacklight stations will be available for you to observe and photograph insects!
The City Nature Challenge is an international competition to see which city can document the most species of living things from April 25-28. The San Antonio effort includes the Texas Master Naturalists, San Antonio Natural Areas, Phil Hardberger Park Conservancy, TPWD and many others. It's easy to participate by joining an event or making observations on your own using iNaturalist! To find out more about CNC 2025 and how to download iNaturalist visit: CNC-SA.org.
