The CalFlora Project is designed as a comprehensive database of plant distribution information for the State of California. CalFlora contains information for over 7,500 ferns, conifers, and flowering plants known to be native or naturalized in California. The photos found in this website are also available through CalPhoto on the UC Berkeley Digital Library, that contains nearly 50,000 images of plants, animals, fossils, people, and landscapes. It provides access to scientific data to identify and monitor issues in plant conservation and biodiversity as well as for use in land use decisions. It also provides access to educational information at many levels. The site consists of three primary components: a species database, an occurrence database, and a nomenclature database. It also provides an elaborate but easy-to-use search engine for California vegetation. Maps are built on the basis of information in the databases. Complementing these searchable databases is access to the CalPhotos library of plant images. Numerous organizations and volunteers support this Project.
