City Nature Challenge 2025

City Nature Challenge - Rochester NY

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 compete 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.


Part One: Take Photos!

Get ready to explore and document the wild side of Rochester! From April 25th to April 28th, we’re calling on nature lovers, photographers, and citizen scientists of all ages to participate in the City Nature Challenge by taking photos of wild plants, animals, and fungi in our area.

Whether you’re in a park, your backyard, or along the Genesee River, every observation counts! Simply snap a photo of any wild species you find and upload it to the iNaturalist app to help contribute valuable data for conservation efforts.

 

Part Two: Identify What You Found!

The adventure continues! From April 29 to May 5, help identify the wild plants, animals, and fungi documented during Part 1 of the City Nature Challenge. Your photos have been uploaded—now it’s time to see what we’ve found!

Visit the Seneca Park Zoo Project Page on iNaturalist to compare observations, help with species identification, and contribute to this exciting community science effort. Whether you’re a nature enthusiast or just curious about local wildlife, every ID helps refine our understanding of Rochester’s biodiversity.

Join two Naturalists for our CNC BioBlitz!

The goal of these Bioblitz’s is to document the variety of plant, animal, and fungal species that exist in and around the City of Rochester. We will hike through these parks and stop to document the organisms we find on the iNaturalist APP. Throughout the hike we will give you opportunities to go out and explore areas on your own to see what you are able find.
