The continual compilation and periodic updating has funneled attention on the de facto rarest vascular plant species in Wyoming. The 2018 list profiles the nature of species’ rarity in bullets (range context, number of occurrences, abundance, recent trends and intrinsic vulnerability) that are expanded in species accounts.
All scientific names follow taxonomic conventions of the Rocky Mountain Herbarium (Nelson 2018). Almost all common names follow the PLANTS database. Users are referred to the table that follows for a merged list of both species of concern and of potential concern that has links to State Species Accounts. The purpose of these accounts is to highlight status information and include maps, illustrations, and photos of both the species and its habitat. We are in the process of expanding state species accounts. This is the most complete information for many species unless they have been addressed in research reports - see references at the end of the species accounts. To access WYNDD reports for species in question, go to the Reports and Publications page. The list below also reflects updates to ranks and status that may not be reflected in the pdf document.
The 2018 list contains over 12% of the state flora and represents an evolution in our understanding. The first Wyoming plant species of concern list was prepared in 1982, based in large part on the information compiled in Dorn (1977). Since that time, over 700 vascular plant species are or have been tracked as species of concern in Wyoming, reflecting discoveries in the state as represented by floristic surveys of the Rocky Mountain Herbarium, species-specific surveys, taxonomic research, and other changes reflected in revisions to the state flora (Dorn 1977, 1988, 1992, 2001) and in updates to the species of concern lists by Robert Lichvar, Hollis Marriott, Walter Fertig, and the current author. The work of maintaining the lists places a premium on collecting and sharing information. New information and questions are always welcome.

All scientific names follow treatment in Dorn (2001). Users are referred to the table that follows for a merged list of both species of concern and of potential concern that has links to State Species Accounts. The purpose of these abstracts is to highlight status information and include maps, illustrations, and photos of both the species and its habitat. We are in the process of populating and entering species abstracts for all species of concern. This is the most complete information for many species unless they have been addressed in research reports as cited in the list of references at the end of the species abstracts. To access WYNDD reports for species in question, go to the Reports and Publications page. The list below also reflects updates to ranks and status that may not be reflected in the pdf document.
