Invented by citizen science staff at the Natural History Museum of Los Angeles County and California Academy of Sciences. The City Nature Challenge is an international effort for people to find and document plants and wildlife in cities across the globe. It’s a bioblitz-style competition where cities are in a contest against each other to see who can make the most observations of nature, who can find the most species, and who can engage the most people.

Started in 2016 for the first-ever Citizen Science Day, the citizen science teams at NHMLA and CAS dreamed up the City Nature Challenge as a fun way to capitalize on their home cities’ friendly rivalry and hold a citizen science event around urban biodiversity. The first City Nature Challenge was an eight-day competition between Los Angeles and San Francisco, engaging residents and visitors in documenting nature to better understand urban biodiversity. Over 20,000 observations were made by more than 1000 people in a one-week period, cataloging approximately 1600 species in each location, including new records for both areas. During the 2016 CNC, we heard so much excitement and interest from people in other cities that we decided we couldn’t keep to the fun just to ourselves. In 2017 the City Nature Challenge went national, and in 2018, the CNC becamne an international event!

There is nature all around us, even in our cities! Knowing what species are in our city and where they are helps us study and protect them, but the ONLY way to do that is by all of us - scientists, land managers, and the community - working together to find and document the nature in our area. By participating in the City Nature Challenge, not only do you learn more about your local nature, but you can also make your city a better place - for you and other species!

Anyone and everyone can participate! The Omaha-Metro Area is participating and will be using the iNaturalist app, free to download on Apple's App Store and Google Play for Android, to track and record its findings.

To see if a city is participating near you, visit CityNatureChallenge.org.

Anywhere nature can be found. Due to Covid-19, please follow safe distancing guidelines.  For this year we want you to do a community event and document what is in your neighborhood, your backyard, your streetcorner.  Let's really find out what Omaha is all about!

Please note: Pets can be included but must be marked as "Cultivated" in the observations. This will be the case when visiting other attractions and wildlife organizations. Plants and animals that are part of an exhibit are "Cultivated". 

More than 160 cities worldwide will be competing to see who can make the most observations of nature, find the most species and engage the most people.
