Help L.A. win the City Nature Challenge!

In April 2018 the City Nature Challenge went global. Participants from nearly 70 cities around the world competed against L.A. to find out which city has the most nature. This year San Francisco won, but check back next year to help L.A. regain the champion spot.

Check out the global City Nature Challenge website for more on the results, history, and for the educator toolkit and other resources.
