How to Participate

Getting involved is easy—and fun!

1. Download the iNaturalist app
It’s free and works on both smartphones and the web. iNaturalist helps suggest species IDs and connects you with a community of experts. Get the app free for Apple and Android. You can also use iNaturalist on your desktop computer.

2. Head outside
Explore your neighborhood, a local park, a trail or even your own backyard. If it’s wild and you didn’t plant or place it there, it counts.

3. Snap a photo (or record a sound)
Upload your observations during the City Nature Challenge event window and watch as the community helps identify what you found.

You can participate on your own or join one of the New Hampshire–based City Nature Challenge projects listed above!

Why It Matters

Every observation—whether it’s a rare orchid or a stubborn sidewalk dandelion—adds to a growing body of open-access data used by researchers, land managers and conservationists worldwide. Together, these observations help us better understand biodiversity and how people and nature can thrive together.

Plus, it’s a great excuse to slow down, look closer and reconnect with the nature right outside your door!
