iNaturalist is a digital platform and app to help you to contribute to biodiversity science. Every observation can contribute to science, from the rarest butterfly to the most common backyard weed. We share your findings with scientific data repositories like the Global Biodiversity Information Facility to help scientists find and use your data. All you have to do is observe.

iNaturalist is a joint initiative of the California Academy of Sciences and the National Geographic Society.

Install iNaturalist mobile apps so you can always observe, even without cell reception or wifi.
