City Nature Challenge

City Nature Challenge has finished for 2023. Check back for 2024!

What is the City Nature Challenge (CNC)?

City Nature Challenge is an annual friendly competition between cities all over the world to find and record the greatest variety of wild living things over an extended weekend.  The first-ever Citizen Science Day took place in 2016 between the Natural History Museum of Los Angeles County and California Academy of Sciences. Together, they dreamed up the CNC as a fun way to capitalize on their home cities’ friendly rivalry and hold an event around urban biodiversity. 
 

Why Participate? 

There is nature all around us, even in our cities! Knowing what species inhabit our metro area and where they are helps scientists study and protect them.
 

How Can You Participate?

Join Omaha's Henry Doorly Zoo and Aquarium staff and volunteers as we unite forces across the metro. This is our chance to get to know the plants, animals and fungi that live in our backyards, neighborhoods, and parks and consider how our lives affect the ecology around us.
There are four ways to participate:
  1. Promote the Challenge - Advertise and spread word about the challenge to your school, club, work, or church. 
  2. Make Observations - Get Outside! Make observations over a four-day weekend and upload your photographs to our project on iNaturalist. 
  3. Host an Event - Have a Green Space or picnic spot? Organize a walk or meditation during during the CNC and encourage co-workers, neighbors, or classmates to get outside and participate in making observations. Omaha's Henry Doorly Zoo & Aquarium hosts events, as well as our partners, on our website so that the general public can find open events in their area. 
  4. Identify Species - Unable to participate in CNC2023 or busy over the weekend? Help us identify species the following week.Host an identification party or go to our project on iNaturalist with friends and verify species using your knowledge, guidebooks, or websites. Wildlife experts, enthusiasts, and nature lovers are welcome!

Frequently Asked Questions

What is the City Nature Challenge?

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.

How it got started?

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!

Why participate in the City Nature Challenge?

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!

Who can participate in the challenge?

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.

Where can I spot wildlife in the Omaha-Metro?

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". 

What other cities are participating?

More than 450 cities worldwide will be competing to see who can make the most observations of nature, find the most species and engage the most people.
