The City Nature Challenge is a friendly competition* among cities across the globe to see which city can find and document the most plants and wildlife over a four-day period.

In 2022, we urge everyone to follow the health directives of your area, including maintaining social distancing of 6 feet between people, wearing your masks while close outside together, and not sharing items like binoculars.  For any observing you want to do in close proximity, please stay safe and consider vaccination status and recent exposure of folks in the group. 

*In these challenging times the focus of the event has shifted from competition to community building.  Let's all get out there and see what we can find!

There is nature all around us—even in our cities. Last year’s challenge saw over 1,270,000 observations made by more than 52,000 people around the globe.  By making wildlife observations, you are contributing data to scientists and your community, which helps the study and protection of local species.  Previous years' participants have documented species in their areas that were completely surprising, species they did not know were there.

Plus, it's true always but especially in the current stressful pandemic, nature is good for you!  Taking a walk in the fresh air, getting some (but not too much!) sun, letting your senses engage with nature, and letting your mind focus on something other than worry are all good for your health.  Exercise is good for you, sunshine gets you necessary vitamin D, using your eyes and ears to focus on a variety of things rather than just your screen is scientifically proven to be good for them, and taking breaks to de-stress is more important than ever.

The overall City Nature Challenge was dreamed up and is coordinated by the Natural History Museum of Los Angeles County and the California Academy of Sciences.  The very first Challenge in 2016 was just between LA and San Francisco.
