Join the 2025 City Nature Challenge!
Coming up April 25th – May 5th, 2025
Started in 2016 as a competition between Los Angeles and San Francisco, the City Nature Challenge (CNC) has grown into an international event, motivating people around the world to find and document wildlife in their own cities.
Run by the Community Science teams at the California Academy of Sciences and the Natural History Museum of Los Angeles County (NHM), the CNC is an annual four-day global bioblitz at the end of April, where cities are in a collaboration-meets-friendly-competition to see what can be accomplished when we all work toward a common goal.
Tri-Valley Conservancy is leading Livermore in participating in the 2025 Challenge, and we would love to have you be a part of it!
How can you participate? Attend an Upcoming “Observation Outing” to help document the wildlife in our parks and open spaces!
