iNaturalist
iNaturalist is a social network of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe. iNaturalist may be accessed via its website or from its mobile applications. As of February 2021, iNaturalist users had contributed approximately 66 million observations of plants, animals, fungi, and other organisms worldwide, and around 130,000 users were active in the previous 30 days. iNaturalist describes itself as "an online social network of people sharing biodiversity information to help each other learn about nature", with its primary goal being to connect people to nature. Although it is not a science project itself, iNaturalist is a platform for science and conservation efforts, providing valuable open data to research projects, land managers, other organizations, and the public.
