Texas Results

The City Nature Challenge is a global, city-scale BioBlitz event that frames an urban biodiversity survey as a friendly competition between cities. Data collection was April 29 to May 2, 2022 and identifications May 3 to 8, 2022.

Texas Numbers

  • 15 Texas projects
  • 93 Texas counties
  • over 148,360 observations
  • over 7,700 species recorded
  • over 6,130 observers
  • over 2,470 identifiers

Restorative Power of Nature United Us
in Challenging Times

Owing to continued challenges with the COVID-19 pandemic, this year’s City Nature Challenge was a collaborative effort rather than a competition. Our Texas metros joined 419 other cities in a worldwide celebration of the resilience of urban nature that logged more than 1.6 million observations of 50,170 plus species made by 67,220 plus people.

Cumulative Impact

56% of all Observations Research Grade
More than half of the observations recorded during the City Nature Challenge in Texas metro areas were Research Grade — observations of wild organisms with photo or sound vouchers of a quality to merit a species-level identification by the majority of identifiers.

Over 2,635 Research Grade Observations of 128 SGCN Species
During the 4 days of the event, participants across all projects recorded over 2,635 observations at Research Grade of 137 Species of Greatest Conservation Need (SGCN). This may provide important insights into how SGCN species are using Texas’ urbanizing landscapes.

Number of Projects Doubles
In 2022, the number of projects increased from 14 to 15 with an additional 15 counties added, bringing the total counties to 93.


The City Nature Challenge is organized by the California Academy of Sciences and the Natural History Museum of Los Angeles County.
