Embark on a fun, real-world adventure that will open your eyes to our beautiful environment and the world of invasive pests. Get outdoors to capture (with photos!) as many insect, weeds and pest animals as you can. You’ll score points for every verified sighting, with extra points if you can identify what you’ve found. And even more points if you find something rare or interesting.

Started in 2016 as a competition between San Francisco and Los Angeles, the City Nature Challenge (CNC) has grown into an international event, motivating people around the world to find and document wildlife in their cities. Run by the Community Science teams at the California Academy of Sciences and the Natural History Museum of Los Angeles County, 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 not only what can be accomplished when we all work toward a common goal, but also which city can gather the most observations of nature, find the most species, and engage the most people in the event.
