It has been found in the Tushar Mountains in Piute County (Taye 4014, 23 July 1988, BRY). Threats to this taxon may be primarily from the grazing-related impacts of cattle and naturalized mountain goats. Goats were introduced by the State of Utah for trophy hunters. Climate change is also a threat. Droughts and rapid snowmelt due to wind-blown sediments are melting snowpack earlier than normal in our region. This is the primary reason for the scoring of the threats to this species to a "1". It is not known if these threats are consistent in the remainder of its range in Utah. Trends are scored as "unknown" due to uncertainty of the magnitude of the impacts of disturbance on extant populations and the lack of population-level surveys.

This taxon was reported for Utah in FNA "Crepis bakeri is generally recognized by the low stature, dense rosettes of pinnately lobed leaves with coarsely dentate lobes, tomentose stems and leaves, stipitate-glandular hairs distally on stems, relatively large involucres, and densely flowered heads. It is considered closely related to C. occidentalis." No vouchers are cited in FNA for Utah nor is any information noted about the notable disjunction in ssp. cusickii. It may be that the author has mistaken a depauperate C. occidentalis specimen for C. bakeri. This taxon has not been included in revisions to A Utah Flora and there is no obvious taxon that Welsh recognizes within which it would fit nomenclaturally.

This taxon's primary range is in Colorado and Wyoming. Habitat Specificity scored as "0" since the habitat does not seem unusual according to FNA ("Dry, rocky soil in open areas"). The one voucher from Utah was collected "sandy clay derived from Moenkopi Formation", but this species does not seem to be a edaphically restricted species. It is apparently not restricted to this habitat type in other parts of its range according to the description in FNA.

These two species are also found across the Nevada state line in White Pine and Nye Counties in similar habitats. Sphaeromeria capitata is not. Although there is a remote chance this is a highly unusual, low elevation Pleistocene remnant population of S. capitata, or Welsh has misidentified this specimen and it is one of the saline valley-spring mound species of Sphaerromeria found in Nevada, of which there are a couple that grow sympatric with Swertia gypsicola and Ivesia kingii, most notably Sphaeromeria potentilloides var. nitrophila.

The species is not cited for Utah in FNA 19: 211. 2006." There is a possibility that this record is a waif. Relocation of this plant at the collection locality is necessary for the determination if there is a self-sustaining population of this species in Utah. As a result, number of individuals is scored as "unknown" Threats are unknown but it is likely minimal since the collection site was within a national park.

Sensu FNA, "Fimbristylis castanea, commonly placed in synonymy of F. spadicea..., a widespread salt marsh perennial of tropical America, is distinguishable by its relatively shorter spikelets, usually lower habit, and by its proportionately shorter involucral bracts. Fimbristylis spadicea is hardy with us only as a greenhouse plant." Apparently, F. spadicea is a misapplied to plants in Utah.

I found no Trifolium specimen at NY from the "Jack Creek" locality, other than the ones from Nevada. Apparently, the specimen Welsh observed at NY has either been re-identified as another taxon, annotated as being from another state, or a combination of both. His proposal that this specimen may be from Nevada has merit. T. cyathiferum is found in eastern NV only in the Independence Range of Elko County. It has been collected several times along Jack Creek. Therefore, it is likely that the specimen was collected in Elko Co., Nevada. The specimen as it stands is now effectively undocumented. As a result of these data, Number of Individuals and Number of Populations is changed from "1" to "unknown".

Further population-level research may show that this taxon is more locally common and should be scored a "0". However since it has only been collected 5 times in the same relative vicinity, it is reasonable to assume this plant is not common in Daggett County and rescoring this taxon as a "1" is warranted. Habitat Specificity rescored a "1" due to its status as a riparian species according to A Utah Flora ("Wet sedge meadow"). It was not documented by the original list why this species scored as "0" when all other riparian species were scored as "1". Threats to this taxon include disturbance from the grazing-related impacts of cattle and naturalized mountain goats. Goats were introduced by the State of Utah for trophy hunters.

It is a species that is mostly in the northeastern U.S. with scattered disjunct populations across the Midwest and Western U.S. Habitat Specificity scored as "1" due to its status as a riparian species according to FNA ("Wet ground in ditches, lake and stream margins, and a variety of other habitats, often a calciphile"). This species has more than 25 populations in Utah (assuming the determination of the SEINet records are mostly correct) and likely is common locally.

Threats to this taxon include riparian habitat modification and disturbance from the grazing-related impacts of cattle and naturalized mountain goats. Goats were introduced by the State of Utah for trophy hunters. Climate change is also a threat.

The closest populations of this taxon to Utah are in Clark County, Nevada. The report from Iron County, Utah may be correctly identified, but the Utah County report is much farther disjunct from the range of the species and should be re-examined. This taxon may also be present in Washington County. Habitat Specificity rescored a "1" due to its status as a riparian species according to FNA ("Eutrophic, quiet waters in temperate regions with mild winters"). Number of Individuals scored as "unknown" since population sizes are not known for this small plant in Utah. This plant has been found in still, eutrophic outflows of springs in the Mojave Desert region, habitats that are becoming significantly degraded by development, ATV-recreational disturbance, and grazing impacts. Species of small, water-dependent herbs are generally overlooked by botanists. Despite this, the habitat for this species is very limited. The situation is complicated by man-made water features. Many of the eutrophic water bodies in the range of this species are not natural, mostly stock ponds and residential reservoirs. It is possible that the populations of this taxon in Utah are not native. It is a high priority to check to see if these populations still exist.

Utah populations are now considered to be C. rivularis. The hisutulous plants with red pomes from the canyons along the Wasatch are now considred this taxon, not C. columbiana. Habitat Specificity scored as a "0" since it does not seem to be a riparian species according to A Utah Flora (" Indigenous on dry gravelly slopes in the mountain brush"). Threats scored as "1" since riparian habitat modification and disturbance related to residential-highway development and grazing-related impacts are impacting canyons in northern Utah. Trends are scored as "unknown" due to uncertainty of the magnitude of the impacts of disturbance on extant populations and the lack of population-level surveys. | Alexander | Aug 2015 | x | ||||||||||||||||||||||||||||||||||||||||||||||||

It is no longer considered a variety of P. diversifolia (which is also now recognized as P. glaucophylla now that the types of P. diversofolia have been determined as a hybrid; even if you recognize var. madsenii as a seperate variety, it has been orphaned without a new combination in the legitimate new names P. glaucophylla or P. plattensis). In A Utah flora, var. madsenii is known only from the type specimen. Including those types, P. planttensis is known from 6 collections at BRY. It has been found in Box Elder, Garfield, Kane, Sevier, and Wayne Counties in Utah. This taxon's primary range is in the Rocky Mountains, Great Plains, and Canada. Habitat Specificity scored as "1" since this taxon appears to be an montane riparian species according to FNA ("Moist meadows, streamsides, reservoir margins"). Disturbance related to wetland development, ATV recreation, and grazing activities may be a threat to this species, however it is scored as "unknown" due to uncertainty. Trends are scored as "unknown" due to uncertainty of the magnitude and types of disturbance on extant populations and the lack of population-level surveys.

Only 5 specimens at BRY have been collected. It has been found only in the Uinta Mountains in Daggett County in Utah. This taxon's primary range is in the northern Rocky Mountains and Canada. Habitat Specificity scored as "1" since it is subalpine meadow and bog species according to A Utah Flora ("Wet meadows with sedges, calamagrostis, and sphagnum"). Threats to this taxon include grazing-related impacts from cattle, sheep, and naturalized mountain goats. Goats were introduced by the State of Utah for trophy hunters. Climate change is also a threat. Droughts and rapid snowmelt due to wind-blown sediments are melting snowpack earlier than normal in our region. These are the primary reasons for the upgrade of the threats to this species to a "1". Trends are scored as "unknown" due to uncertainty of the magnitude of the impacts of disturbance on extant populations and the lack of population-level surveys.

Numerous riparian species have not been relocated in this area for over 40 years. These are the primary reasons for the upgrade of the threats to this species to a "1". Trends are scored as "1". It is downward. [2018 - taxon is believed to be exptirpated and if treated as a variety/species, extinct, perhaps the first documented extinction of a globally rare species with a distribution in Utah. The lake's water level was changed starting with a dam in 1935 and the level rose over time changing the water depth and temperature and then combined with introduced species via boating and other human-caused impacts.] | Alexander/Frates | 12/1/2014/Oct 2018 | x | ||||||||||||||||||||||||||||||||||||||||||||||
