Taxonomic Checklist Data Contributors:
John Kartesz, Biota of North America Program, provided the foundational U.S. vascular plant
checklist, state and county distribution, and the original duration, growth habit, and native
status data used in PLANTS. NRCS is pleased to have significantly
funded BONAP and supported the development of this critical land management
information from 1990 until 2006.
Luc Brouillet (Université de Montréal) and Canadian colleagues generously donated Canadian
vascular plant names with distribution and attributes in 2006. Vascular data—especially native
status and scientific name authorities and orthography—have since been partially revised by
Mark Skinner, former NPDT employee, and will continue to be revised internally and by external specialists for the
foreseeable future.
Robert Egan (U. Nebraska at Omaha) and Theodore Esslinger
(North Dakota State University) provided the North American
lichen checklist, which is periodically published in The
Bryologist.
Lewis Anderson and Molly McMullen of Duke University provided
the original North American moss checklist, and it was updated
by Marshall Crosby of the Missouri Botanical Garden.
Ray Stotler and Barbara Crandall-Stotler of Southern Illinois
University, Carbondale provided the North American liverwort
and hornwort checklists.
Checklist higher taxonomy
was developed by Mark Skinner and Deiter Wilken.
