City Nature Challenge 2019-04-24T17:53:16-05:00

Be part of an international effort to document wildlife across the globe, and discover the natural diversity in Delaware.

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.

The challenge is in two parts. From April 26-29, take photos of wild plants and animals and upload to iNaturalist, then from April 30-May 5, uploads will be reviewed and identified.

While the City Nature Challenge primarily focuses on cities, observations from anywhere in Delaware are welcome. Knowing what species are in our area and where they are helps scientists study and protect them. By participating in the City Nature Challenge, you’ll learn more about local nature, and make our area a better place—for you and other species!

We’re using iNaturalist to collect observations. Here’s how to get involved!
