Abstract: In 2005–2006, the National Park Service’s Northern Colorado Plateau Network received funding to develop a revised checklist of the vascular plant ﬂora of Canyonlands National Park. This entailed a thorough review of existing literature, reexamination of specimens from the Canyonlands National Park herbarium and other state and national museum collections, and additional ﬁeld work to corroborate unveriﬁed species reports or locate new species. Based on this study, 594 vascular plant taxa have been conﬁrmed or reliably reported as occurring in the park (534 are known from validated herbarium specimens and 60 from unvouchered literature reports). Another 100 species formerly considered part of the park ﬂora have now been shown to be falsely reported. The current ﬂora of Canyonlands National Park represents 16.5% of the known ﬂora of Utah, and 35.1% of the ﬂora of the Colorado Plateau ecoregion within Utah. At least 45 of these species are either listed as sensitive by various agencies or considered species of concern by the state natural heritage program. Introduced plants make up 11.4% of the park ﬂora (68 species), of which only seven species are considered noxious weeds by the State of Utah. Further surveys in Canyonlands National Park are likely to ﬁnd additional new species (at least 161 are known from similar habitats outside the park boundary), especially among late-ﬂowering, weedy, or wetland taxa. This checklist includes updates made in 2011 and 2012.
