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.
