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 28 to May 1, 2023 and identifications May 2 to 7, 2023.

Texas Numbers

  • 15 Texas projects
  • 93 Texas counties
  • over 173,685 observations
  • over 7,647 species recorded
  • over 6,050 observers
  • over 3,123 identifiers

The Global Experience

Our Texas metros joined 486 other cities in a worldwide celebration of the resilience of urban nature that logged more than 1.8 million observations of 58,543. plus species made by 69,730 plus people.

Cumulative Impact

64% 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./p>

Over 3,697 Research Grade Observations of 177 SGCN Species
During the 4 days of the event, participants across all projects recorded over 3,697 observations at Research Grade of 177 Species of Greatest Conservation Need (SGCN). This may provide important insights into how SGCN species are using Texas' urbanizing landscapes.

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