The City Nature Challenge is Now Live!  Invented by community science staff, Lila Higgins at the Natural History Museum of Los Angeles County (NHM) and Alison Young and Rebecca Johnson at the California Academy of Sciences (CAS), 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 friendly contest with 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 all got started  Started in 2016 for the first-ever Citizen Science Day, the community science teams at NHM and California Academy of Sciences dreamed up the City Nature Challenge as a fun way to capitalize on their home cities’ friendly rivalry and hold an 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.     In its first year, over 20,000 observations were made by more than 1,000 people in a one-week period, cataloging approximately 1,600 species in each location, including new records for both areas. During the 2016 CNC, there was so much excitement and interest from people in other cities that the organizers knew they couldn’t keep the fun just to themselves. In 2017 the City Nature Challenge went national, and in 2018, the CNC became an international event!     City Nature Challenge Leadership     Lila Higgins (they/them)  Co-Senior Manager, Community Science and City Nature Challenge co-founder Natural History Museums of Los Angeles County  Lila, who joined the Natural History Museum of Los Angeles County in 2008, is an informal educator with almost two decades of experience in museum education and community science programming.

About

The City Nature Challenge is a collaboration-meets-friendly-competition to see what can be accomplished when we all work toward a common goal of observing nature in urban settings. The big three results, highlighted here, are for the total number of observations, species, and people who participated, all around the world. Below, you will find the contributions of each city to these total numbers.   Loading...

Live Results

The City Nature Challenge is Now Live!  To view in Spanish, click .      Why participate?  There is nature all around us! 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!   Taking Part is Easy   It can be any WILD plant, animal, fungi, slime mold, or any other evidence of life found in your city. Take a picture or record the sound of what you find. Be sure to note the location of the critter or plant. Share your observations through iNaturalist or your city’s chosen platform. If it’s planted or taken care of by people it is not WILD. Mark it captive/cultivated!

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!

Taking Part is Easy

Welcome to the City Nature Challenge Education Toolkit! &nbsp;We are currently updating our resources. In the meantime, we hope you will find these past activities for both formal and informal education settings useful. &nbsp;While many of the activities are meant for groups, many can be adapted for use at home as well.
