Utah globally rare plants

List of vascular plant taxa (total of 273 taxa, 24 federally listed, 1 proposed threatened, 3 candidates)
 
For G-rank explanation, see NatureServe Conservation Status
 
ESA status codes: LE=listed as endangered; LT=listed as threatened; C=Candidate species; PE=Proposed Endangered; PT=Proposed Threated; EM=Emergency listing package submitted; NOR=Notice of review
 
See bottom of this page for a brief discussion of taxa formally federally listed from Utah.
 
Note: the UNPS priority list column is in progress. Also, this list does not yet include all of the taxa included on the 2009 UNPS rare plant list. See the 11/1/09 What's new section for more details and links. The 2009 UNPS Utah rare plant list published 11/01/09 should be taken into account whenever considering project impacts to rare plants and not just the list presented here. See the November 2009 Sego Lily in which the criteria used in developing this list is discussed.

C. virginense has been lumped with C. mohavense in the Flora of North America (vol 19, pg 134), and the distinction between perennial (C. virginense) and biennial (C. mohavense) may not be valid. Even if recognized as C. mohavense it would remain rare in Utah at the periphery of its range here, and since C. mohavense is a globally rare species. 		Virgin thistle Sunflower G2 H

Taxa formerly federally listed in Utah
 
Astragalus perianus: listed as threatened effective 5/27/78, delisted eff. 10/16/89, more information (species was listed prematurely prior to being properly surveyed, the indication that it "recovered" by FWS is not accurate; still considered rare and is therefore contained in the list of globally rare plants above; the first ever plant species to be delisted under the Endangered Species Act and for reasons unrelated to taxonomy, delisting action was initiated by Dr. Duane Atwood then of the USFS)
 
Echinocereus engelmanii var. purpureus: listed as endangered 10/11/79, delisted eff. 12/27/89, more information (no longer considered a valid taxon, however, there remains a purple-spined form of Echinocereus engelmanii that warrants conservation attention)
 
Echinocereus triglochidiatus* var. inermis: listed as endangered eff. 12/7/79, delisted eff. 9/22/93, more information (while no longer considered a valid taxon, this mostly spineless form of what is actually Echinocereus mojavensis* still warrants and receives management attention; *as now understood and unrelated to prior disposition of the "inermis" variety , the species Echinocereus triglochidiatus does not occur in Utah)
 
Erigeron maguirei: listed as endangered effective 10/7/85 (FR 9/5/85), reclassified to threatened effective 7/19/96 (FR 6/19/96), delisted eff. 2/18/11, more information
