The on-line version of the Atlas of Utah Plants is a revision of the Atlas of the Vascular Plants of Utah by B. A. Albee, L. M. Shultz, and S. Goodrich, published by the University of Utah Museum of Natural History in 1988. Since the original Atlas was published, many names have changed and new species have been described. The new version includes more than 500 name changes, approximately 8,000 new location records, and more than 400 records not included in the 1988 publication. The new version is a real-time mapping system that displays old and new records on a satellite image of Utah. When you are viewing the distribution map, clicking on a point will allow you to see the source of the information (see explanations below) and the elevation of the specific location.
Development of the digital version started shortly after publication of the hard copy version. Working in the Remote Sensing/Geographic Information System laboratory of Utah State University, technicians spatially referenced 77,000+ locations for 2,438 species mapped in the original Atlas (Ramsey and Shultz 2004). The first on-line version was posted to a web site in 1992.
The current revision includes locations for the 399 rare species that were not mapped in the original atlas, and 20 species described since 1988 (Welsh et al. 2003; IPNI). The new records include more than 6,000 locality records from the Utah Natural Heritage program data files that are mapped at the resolution of township and range (specific locations are maintained by the heritage offices of the Utah Division of Wildlife Resources (DWR) Other records are drawn from GPS-referenced location records from the Utah Valley State College Herbarium (UVSC), various College of Natural Resource projects which provided vouchers to the Intermountain Herbarium (UTC) of Utah State University, and vouchers from the Grand Staircase Escalante Monument (Fertig et al. 2005). The revision also includes locations for species described since 1988. Name changes that result from nomenclatural revisions (Flora of North America 1992 - 2006) involve approximately 16% of the names in the Utah flora (USDA Plants Database). We worked to make the transition to new names as painless as possible. Old names are provided in italics, and you can reach the new name by clicking either on the old, italicized name, or the new name in the list. Common names link to the current nomenclature as well.
In addition to new maps and new records, we have provided species checklists for floristic provinces derived from ecoregions from The Nature Conservancy 2006.

Scores of professionals and well-informed amateurs who have collected throughout Utah since the mid-1850's and prepared voucher specimens for deposit in natural history collections provide the basis for this work. Authors of the original atlas (Albee et al. 1988) spent approximately seven years critically examining and mapping locations for more than 300,000 collections housed in Utah herbaria. The maps show locations for herbarium collections housed at the S. L. Welsh Herbarium of Brigham Young University (BRY), the Garrett Herbarium of University of Utah (UT), and the Intermountain Herbarium of Utah State University (UTC), as well as from a number of National Parks, Forests, and Bureau of Land Management collections [original maps with source codes are archived at UT]. After 1988, Bonnie Banner, Thadeus Tilton, Tom Van Neil, Kent Braddy, Chris Garrard, and of the Remote Sensing Lab of USU, worked to bring these collections into a geo-referenced database and create the digital interface. Doug Ramsey had the vision and technical expertise required to begin the digital project, and the patience to continue. Wanda Lindquist created the links to nomenclatural revisions and species checklists, and designed the original web interface. Chris Garrard designed the current web interface. Any errors (commission or omission) in reporting plant names and distributions must, however, rest with Leila Shultz. New information may be reported directly to her at firstname.lastname@example.org.
Funding for this revision was provided through a grant from the Bureau of Land Management.
