Addendum
Since this paper was written in the summer of 2009, 31 new vascular plant taxa have been collected or reported for
Cedar Breaks National Monument, increasing the flora to 385 species and varieties (Fertig et al. 2012). Among the
more uncommon or noteworthy additions to the monument's flora are Botrychium lunaria (sparse in Utah and the first
species of Ophioglossaceae for Cedar Breaks), Cirsium clavatum var. clavatum (a regional endemic, first collected in
1982 and located in a search of specimens at the Brigham Young University herbarium), and Penstemon caespitosus
var. suffruticosus (a local endemic of southern Utah).
In recent years, local political leaders in Iron County, Utah, have proposed changing Cedar Breaks from a national
monument to a national park and having the park annex the Ashdown Gorge Wilderness on its western boundary. I
conducted a floristic survey of the Ashdown Gorge Wilderness in the summer of 2009 (Fertig 2009g) and documented
308 vascular plant taxa. Of these species 247 were previously known from Cedar Breaks National Monument,
while 61 were new species for the local area. If the Ashdown Gorge Wilderness Area were added to Cedar
Breaks National Monument the total flora would increase to 426 taxa (Fertig 2009g).
