2010 BONAP North American Plant Atlas

North American Plant Atlas


                                      Map Color Key:


  Species present in state   and native


Species present and not rare Species extinct Species native, but adventive in state  Species waif


  Species present in state   and exotic

Species present and    rare


    Species noxious  (includes noxious-weed seeds) Species eradicated  

Species not present in state Species extirpated (historic) Species exotic and present Questionable Presence (cross-hatched)  

In some cases, individual species maps will have multiple colors regarding nativity [e.g., Chenopodium album, dark olive green (native), orange (native historic), teal (adventive), and also dark navy blue (exotic)]. This map suggests that in various U.S. states, at least one infraspecific taxon of the species complex is native, another is exotic, a third is adventive and the fourth rare. Once published, the Floristic Synthesis will show state-level nativity and rarity for each infraspecific taxon, however, for this website, we have provided only full species-level maps.
