This interactive map displays species observations from Hanauma Bay recorded on iNaturalist, a global biodiversity platform that combines community participation with scientific research. iNaturalist allows people to upload photos or audio of plants, animals, and other organisms, each tagged with a date and location. Identifications are confirmed through a mix of expert community input and computer-vision tools, creating a publicly accessible record of biodiversity that scientists, conservationists, and nature enthusiasts can use.

The observations shown here come from visitors, researchers, and local community members who have documented marine and coastal species within Hanauma Bay. Using Esri’s mapping technology, these records, over time, can reveal patterns in species presence, seasonality, and distribution, helping to track changes in this ecologically and culturally important reef ecosystem.
