iNaturalist is an online community of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe. Observations may be added via the website or from a mobile application. The observations provide valuable open data to a variety of scientific research projects, museums, botanic gardens, parks, and other organizations.
iNaturalist.org began in 2008 as a UC Berkeley School of Information Master's final project of Nate Agrin, Jessica Kline, and Ken-ichi Ueda. Nate Agrin and Ken-ichi Ueda continued work on the site with Sean McGregor, a web developer. In 2011, Ueda began collaboration with Scott Loarie, a research fellow at Stanford University and lecturer at UC Berkeley. Ueda and Loarie are the current co-directors of iNaturalist.org. On April 24, 2014 iNaturalist.org merged with the California Academy of Sciences 
As of 7 November 2014[update], the iNaturalist community consisted of more than 37,000 users contributing over 1,000,000 observations of plants, animals, and other organisms worldwide. Users have created and contributed to over 2000 different projects, spanning hundreds of themes. A few project examples include taxa- and location-specific bioblitzes, roadkill observations, animal tracks, and documenting the spread of invasive species.
