BONAP's North American Plant Atlas (NAPA)
(US County-Level Species Maps: List by Genus)

The Biota of North America Program (BONAP) maintains relatively complete phytogeographic and related botanical databases for all free-living vascular plants in North America (north of Mexico). For over four decades, BONAP has worked collaboratively with many federal and state government agencies, private groups and individual specialists across the continent to produce and edit our databases. Therefore, we feel that our county-level database has matured sufficiently to allow us to post, for the first time, all of our integrated county-level maps of the North American ferns and allies, conifers and flowering plants in one place. Although these maps must still be considered DRAFT releases, inasmuch as in 2009 alone, nearly 952,000 new county-level records were added, we wanted to provide members of the North American plant community an opportunity to view and critique all 21,500 species-level maps. BONAP plans to provide updates of these maps at regular intervals subsequent to this January 2010 initial release.

North American plant genera, e.g., Bolbitis, that occur within our study area, but restricted to insular islands of the Gulf of Mexico and the Caribbean, such as Navassa, Puerto Rico, U.S. Virgin Islands, are not mapped.
