The City Nature Challenge
Which city on Earth has the most nature and the most engaged residents? The City Nature Challenge—an international community science effort to discover and document plants and wildlife in cities across the globe—aims to find out!
Explore Your World
The City Nature Challenge encourages people to discover and document the biodiversity of our urban spaces. What began in 2016 as a friendly challenge between Los Angeles and San Francisco has now grown to an international event!
There are still many ways to look for nature in your home or backyard. Discover the plants that are growing on their own and the insects and pollinators that live in and around our homes and yards. You never know what you might find!
How to Find Insects
Insects are probably some of the easiest organisms to find in and around our homes, since they’re abundant and incredibly diverse! But where should you look to find them? What can you use to catch them?
These sites provide some guidance on how to find and temporarily hold insects. Be sure to release them after you've posted your observation on iNaturalist!
Moth Lighting
Setting up a light and a sheet to attract moths is a simple and easy way to bring more nature into your backyard. Photographing moths on the sheet is easy, and you’ll definitely attract other flying insects as well!
Science Friday has a great set of instructions for observing moths, and the California Center for Natural History has instructions for building your own moth light to attract a wider variety of moths.
Get Involved
It’s easy to get involved using the iNaturalist app (free on the App Store and Google Play). Just take a picture of a plant or animal and upload it to the app. Any observations made in the Baltimore or Washington, DC metro challenge areas will count during the four-day challenge.
