iNaturalist is a citizen science platform and mobile app that allows users to record and share observations of wildlife. By taking photos of plants, animals, and fungi, users can upload their findings to the platform, where they can receive help with identification from a community of naturalists and scientists. The app promotes biodiversity by encouraging people to explore their local environments and contribute to scientific research. Observations made on iNaturalist are often used by researchers and conservationists to track species distribution and monitor ecological changes over time.
