Project Noah is a citizen-science platform and nature documentation community that enables users to record, share, and identify wildlife observations from around the world. Through its mobile apps and website, participants upload geotagged photos of plants, animals, and fungi, contributing to a global biodiversity database used by educators, naturalists, and researchers. Project Noah also hosts “missions”—community challenges focused on particular species, habitats, or conservation goals—encouraging engagement and environmental awareness. By blending social networking with field observation and ecological data collection, Project Noah fosters a collaborative approach to biodiversity monitoring and nature exploration.
