Participatory citizen science is an increasingly popular tool which provides non-formal education and learning activities. iNaturalist—a free open-access—participatory citizen science platform provides a place to engage the public in natural resource programming. Here, we explore practical applications for integrating iNaturalist into extension programming. We highlight two approaches: (1) self-guided programming, where participants independently engage in biodiversity documentation and professionals contribute identifications, and (2) facilitated programming, which involves extension professional led structured events and projects. We discuss the unique advantages of using iNaturalist in these contexts and offer recommendations for quantitatively measuring and reporting its impact in extension programs.
