What is a bioblitz?

It's an attempt to catalog all living things in Planet Earth.

The City Nature Challenge is a friendly annual competition to see which area can catalog the most observations, species and participants. Through the awesome efforts of Citizen Scientists such as yourself, San Antonio Metro Area had dominated the competition not only in Texas, or the US but the ENTIRE FREE WORLD. But we cannot do it without your help so ....

PLEASE join us on April 24-27th, 2026 for 1, 2, 3, or all 4 of our local bioblitzes.
