City Nature Challenge Presentation: Bringing the world together for biodiversity
Join Malia Cafasso, TerraCorps Community Engagement Coordinator at Audubon Society of Rhode Island and Stormwater Innovation Center, to learn about how to use iNaturalist and how to participate in the City Nature Challenge. The City Nature Challenge (April 24–27), is an annual international event to collaboratively record as many wildlife observations as possible during a four-day challenge. People from all over the world explore nature in their neighborhoods and cities to find and document wildlife. 2026 marks Rhode Island’s 5th year participating, and needs community members like you to help record as many species as we can. iNaturalist, a free smartphone app, allows anyone to photograph and identify plants and animals while contributing to real scientific research. Scientists and conservation organizations use this community-collected data to monitor biodiversity and track environmental change. Come learn how your iNaturalist observations can make a difference in Rhode Island’s City Nature Challenge 2026!
Cost: Free (attendees receive Free Museum Admission on April 23)
