City Nature Challenge is a global event where cities collaborate to observe and document wildlife in their areas. Started in 2016, this annual four-day bioblitz, organized by the California Academy of Sciences and the Natural History Museum of Los Angeles County, has now grown into an international phenomenon. Participants from around the world come together to take pictures of wild plants and animals from April 26 to April 29, 2024, and then identify their findings from April 30 to May 5, 2024.
The results will be announced on May 6, 2024. By participating, you contribute to scientific research on biodiversity and support coexistence with nature. Join this unique initiative to explore and appreciate the natural world in your own city.
If you missed the sign-ups for 2024, prepare to organize your city for the 2025 City Nature Challenge next September
