BONAP maintains relatively complete phytogeographic and related botanical databases for all free-living vascular plants found in North America (north of Mexico). For over four decades, we have worked collaboratively with many federal and state government agencies, private groups and individuals 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 all of our integrated county-level maps for the North American ferns and allies, conifers and flowering plants. BONAP plans to provide periodic updates of these maps at regular intervals. Please see our TDC page for additional data.
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.
