The 2022 Recap

Every spring, cities from around the world compete in the City Nature Challenge, a four-day nature observation competition, in an effort to help document urban biodiversity. Held April 29 – May 2, the City Nature Challenge 2022 marked the 7th annual international bioblitz with the most impressive global results yet.

Global Results

The global results of the City Nature Challenge 2022 show a record high for participation by nearly 500,000 observations and 15,000 observers. This year, more than 67,000 people participated from 445 different cities, collecting a grand total of 1,694,877 observations. Of those observations, more than 50,000 unique species have been identified, 2,244 of which were rare or endangered species. Visit the official City Nature Challenge website to view the full results.

In partnership with NextGen Policy, Councilman Eric Guerra, Miridae Living Labs, the Insight Garden Program, and NorCal Resist we hosted our first in-person event since 2019 at Oki Park, Sacramento. We also hosted a bioblitz at Peregrine School in Davis, where students uploaded more than 200 observations of wildlife on campus.
