About the event
Join Connecticut River Conservancy and partners throughout the watershed for the 2026 City Nature Challenge from April 24 to April 27! Take note of observations on land, in the sky, and in our waters. Start in your backyard or head to your favorite local preserve. We will look, listen, and document our watershed's abundant and unique biodiversity together.
Participate by following these steps:
Make an iNaturalist account.
Join one of the watershed projects listed below that is closest to you.
During April 24-27, 2026, head outside to make observations in iNaturalist. Take photos of plants, animals, and fungi anywhere in the listed project areas. Consider joining one of the guided City Nature Challenge walks led by CRC or our partner organizations and learn more about your watershed with community.
Upload your observations at home or in the field, and they'll automatically be added to a project.
