City Nature Challenge 2024

Are you curious about your local environment? Do you wish you knew the name of that flower in the sidewalk, the fly on the wall? City Nature Challenge is coming, and every observation of the life around you contributes to this international effort to document it. The opportunities to get involved abound, whether on your own or as part of a local event, including with One Tam! Mark your calendars for our dates below...

...What’s City Nature Challenge? This international celebration of the incredible diversity of life all around us happens in two parts: an observation period and an identification period. All you have to do is take pictures of wild-growing living things you observe and upload them to the iNaturalist app. No experience is needed to participate, and your participation matters – what you observe becomes information that scientists can use. What better way to celebrate Earth Day than to learn about what lives here? Learn more and plan your participation >>
