Our Federal Partners
Natural Resources Conservation
Service (NRCS)
The National Plant Data Center sponsors
the PLANTS database. Its staff serve as stewards for much of
the data found in PLANTS and related applications. The Information Technology Center leads development for NRCS
plant-related computer applications. The ITC coordinates work
on plant-related software at the USDA, National
Information Technology Center, Agency Applications
Services Division. Other NRCS partners include the Ecological Sciences
Division and the NRCS National Technical Support Centers.
Environmental Protection Agency
(EPA)
EPA is a primary
partner in the development of the Integrated Taxonomic Information System.
Integrated Taxonomic Information
System (ITIS)
The Integrated Taxonomic Information
System is a collaboration of US, Canadian, and Mexican
agencies, other organizations, and taxonomic specialists
to produce an on-line authoritative list of biological names
for the biota of North America. PLANTS contributes the US
lichens and vascular and non-vascular plants to ITIS.
Smithsonian
Institution, National Museum of Natural History (NMNH)
The National Plant Data Center and the NMNH Botany
Department cooperate to add images to PLANTS, and to
develop a Pacific Basin vascular plant checklist. The NMNH
is a partner in the Integrated Taxonomic Information System.
US Army Corps of Engineers
The Construction Engineering Research
Laboratory, Champaign, Illinois, has been the primary
funding partner for the development of the VegSpec software
tool and the supporting plant data that are developed by
the National Plant Data Center.
USDA, Agricultural Research
Service (ARS)
The USDA ARS Systematic
Botany and Mycology Laboratory and the Germplasm Resources Information System work with the National
Plant Data Center on the verification of the nomenclature
and taxonomy of plant species external to the U.S. ARS is
also a partner on the Integrated Taxonomic Information
System. The Bee
Biology and Systematics Laboratory provided pollinator/host
plant data.
USDA, Animal and Plant Health
Inspection Service
The Plant Protection and Quarantine office
in Riverdale, Maryland has supported the PLANTS database since
1989. PLANTS information is used to identify plant materials
in interstate commerce and at customs ports. The NRCS National
Plant Data Center collaborated with the Center for Plant Health Science & Technology, Plant
Epidemiology & Risk Analysis Laboratory to improve
the capability of the PLANTS Web site for handling invasive
plant information via the development of the Distribution
Update module.
USDA, Farm Services Agency (FSA)
The FSA provided
support for the development of PLANTS Version 3.0.
USDA, Forest Service
The NRCS and Forest
Service cooperate to provide natural resource information
to their respective agencies. PLANTS is now integrated into
the Forest Service Natural Resources Information System (NRIS).
USDA, Rural Development
Rural Development provided
support for the development of PLANTS.
USDI, Bureau of Land
Management (BLM)
The BLM provided support for
the maintenance of the PLANTS vascular plant checklist.
USDI, Fish and Wildlife
Service, National Wetland Inventory (NWI)
The National Plant Data Center and the NWI, Branch of Habitat
Assessment have worked together for years. The NWI Wetland
Plant Indicator Status list is integrated into PLANTS and based
upon PLANTS taxonomy. We have also cooperated with the Fish
and Wildlife Service and others to develop an automated polyclave
key for the identification of wetland species.
USDI, Geological Survey (USGS)
The National Plant Data Center is working with the USGS
Biological Resources Division on a number of items, including
the Integrated Taxonomic Information
System.
USDC, National Oceanic and
Atmospheric Administration (NOAA)
NOAA, particularly the National
Marine Fisheries Service and the National Oceanic Data Center,
is a major partner in the development of the Integrated
Taxonomic Information System.
Our Data Development and
International Partners
Lichens
Robert Egan (U. Nebraska at Omaha) and Theodore Esslinger
(North Dakota State University) assembled the lichen checklist in PLANTS, which is based upon the North
American lichen checklist published periodically in the Bryologist.
The checklist will be revised to include Hawai’ian lichens
in cooperation with George Staples and his staff at the Bishop
Museum in Honolulu. Roger Rosentreter of the Bureau of
Land Management provided some of our lichen common names from
an unpublished manuscript. Future updates of the lichen
list are planned.
Liverwort and Hornworts
Ray Stotler and Barbara Crandall-Stotler of Southern Illinois
University developed these checklists, which cover continental
North America north of Mexico. The hornwort nomenclature is
current and complete, the liverwort data less so. We expect
a comprehensive and fully synonymized liverwort checklist to
be available when Volume 29 of the Flora
of North America is published. Hawai’ian hepatics,
as assembled by the Bishop Museum, Honululu, will be included in the future.
Mosses
The mosses are scheduled for update when the Flora
of North America Volumes 27 and 28 are published. Volume
27 is due out in 2006. Marshall Crosby of the Missouri
Botanical Garden updated our current moss checklist
in association with botanists working on bryophytes for
the Flora
of North America. Lewis Anderson and Molly McMullen
of Duke University developed the original list from a checklist
published in The Bryologist. The mosses now in PLANTS
occur in continental North America north of Mexico. We
expect to incorporate Hawai’ian mosses through collaboration
with the Bishop
Museum.
Vascular Plants
The Biota of North America Program (BONAP),
under the direction of Dr. John Kartesz, has provided vascular
plant data since the inception of PLANTS.
BONAP’s botanical checklist, in development for more
than two decades, is based upon 1) compilation of botanical
literature; 2) assessment of the vascular plant collection
available at the University of North Carolina at Chapel Hill
and other institutions; 3) specialists' review; and 4) field
data collected over the past 25 years. BONAP has worked with
over 600 botanists to develop the North American vascular plant
checklist.
Individual Contributors
to PLANTS
PLANTS data are derived from many sources, none more significant
than the hundreds of experts who have cooperated with BONAP to
develop the vascular plant checklist. However, the list that
follows is not restricted to those who have contributed directly
to BONAP, nor is it exhaustive. If we have inadvertently omitted
your name, please
tell us and we will be pleased to acknowledge your contribution.
