SUMMARY The Pryor Mountain Desert of southern Carbon County has one of the most unusual floras in Montana. The arid climate and unusual and varied soils provide numerous desert-like habitats that are otherwise unknown in the state. Furthermore, this region lies at the north end of the Bighorn Basin, a broad trough that may have served as a migration route from the Red Desert of southern Wyoming. As a result, numerous species of desert plants reach the northern limit of their range in the Pryor Mountain Desert. Many of these species occur nowhere else in the state. For these reasons, the Pryor Mountain Desert is important for the conservation of biological diversity in the Northern Rocky Mountains region. The purpose of our study was (1) to determine which of the rare plants may be threatened or endangered in the area, (2) locate and map these elements of diversity, and (3) use this information to delineate special management areas that efficiently protect the biological diversity of the region. We surveyed the 65,000-ha study area for 35 species of vascular plants listed as species of special concern or of limited distribution by the Montana Natural Heritage Program. Efforts were concentrated in areas of high habitat diversity. We mapped locations, estimated population density, and recorded soil and vegetation information for each population observed. We located nearly 900 populations of target species, including six rare species previously unknown from the area and four species previously unknown from Montana. From these data, we determined that 26 of the 41 target species were common in the study area. We mapped the occurrences of the remaining 15 high-priority species and determined that a special management area located in ca. one township in the Gypsum Creek-Crooked Creek area would protect populations of half of these species. Sensitive plant species may be threatened by exotic weed encroachment, livestock and feral horse grazing, off-road vehicle use, and oil and gas development. INTRODUCTION The Pryor Mountain Desert region of southern Carbon County, Montana has one of the most unusual floras in the state (Dorn 1978, Lesica et al. 1984). The arid climate and unusual and varied soils provide desert-like habitats that are otherwise unknown in Montana. Furthermore, this region lies at the north end of the Bighorn Basin, a broad trough that extends south to the Red Desert of southern Wyoming. The Bighorn Basin has undoubtedly been a migrational pathway for desert plants (Dorn 1977). For these reasons, numerous species of desert plants reach the northern limit of their range in the Pryor Mountain Desert (Lichvar et al. 1985). Many of these species occur nowhere else in the state. In addition, at least four species are endemic to limestone-derived substrates in this region. The Montana Natural Heritage Program lists 24 species of special concern occurring in the Pryor Mountain Desert. In addition, there are 11 species of limited distribution found in the area (Lesica et al. 1984, Lesica and Shelly 1991). Much of the desert below 1980 m (6500 ft) is public land administered by the Bureau of Land Management. Many populations of rare plants occur on these public lands. Although the presence of these plant species in the area has been documented, the size and number of populations has never been assessed. It is necessary to determine which species are truly rare and which are locally common in order to afford protection to those species that are most sensitive. The purpose of this study is to survey BLM lands in the Pryor Mountain Desert and document the presence and size of rare plant populations. THE STUDY AREA The Pryor Mountain Desert lies at the north end of the Bighorn Basin in south- central Montana and adjacent Wyoming (Figure 1). It is bordered on the north by the Pryor Mountains, a northwest extension of the Bighorn Mountain Range. The Prj'ors are a large dome-shaped range rising to nearly 2740 m (9000 ft), composed of Paleozoic sedimentary formations, principally Madison limestone. Numerous canyons incised in the limestone occur on the south slope of the range. The east boundary of the Pryor Mountain Desert is formed by the Bighorn River which has formed a spectacular canyon in the sedimentary formations of the Bighorn-Pryor uplift. The slopes of the Bighorn Mountains rise abruptly on the east side of the River. This portion of the river has been impounded, and it and a strip of land 2-6 miles wide on the west side comprise Bighorn Canyon National Recreation Area administered by the U. S. Park Service. The valley of the Clarks Fork of the Yellowstone River forms the west boundary of the Pryor Mountain Desert. Just to the west of the Clarks Fork is the east slope of the Bearlooth Mountains which rise to over 3800 m (12,500 ft). The Pryor Mountain Desert lies in the rain shadow produced by this massive uplift. The southern border of the region is formed by the valley of the Shoshone River in Wyoming. Figure 1. Map of Pr>or Mountain Desert study area. The study area consists of that portion of the Pryor Mountain Desert north of the Wyoming border and below the Douglas fir zone on the south slope of the Pryor Mountains (ca. 1980 m). Lowest elevations are ca. 1220 m (4000 ft) at thesouthwest end of the study area. We did not conduct sur\'eys on Bighorn Canyon N.R.A. or on private lands within the study area. The oldest formation outcropping in the study area is the Madison limestone which forms the south slopes of the Pryor Mountains. On more level terrain south of the mountain slopes, younger formations overlie the Madison limestone. These are Paleozoic and late Mesozoic sediments, predominantly sandstones and shales. The red sandstones and siltstones interbedded with thin lenses of gypsum of the Chugwater formation are particularly conspicuous (Richards 1955). A geologic history of the area is provided by Knight et al. (1987). Soils in the study area are entisols, mollisols and aridisols (Kratz 1988). In general, soils in the northeast portion of the study area are sandy and often calcareous, while those in the south and west portions have a higher clay content and are often saline. Very sandy soils occur locally where they weather from sandstone outcrops. Productivity of the vegetation is low due to the arid climate. As a result, soil development is minimal and organic matter is low. Shallow soils formed over Chugwater sandstone are particularly barren. Climate of the study area is semi-arid. Bridger, Montana, 16 km (10 miles) north of the west end of the study area at 1100 m (3680 ft), receives an average of 323 mm (12.7 in) annual precipitation, and mean daily temperatures for January and July are -5.8'' C (21.5° F) and 21.4° C (70.5° F), respectively (NOAA 1982). Lovell, Wyoming, 16 km (10 miles) south of the east end of the study area at 1160 m (3800 ft), receives an average of 180 mm (7.1 in) precipitation annually. Daily temperatures averaged -4" C (16.8° F) in January and 22.0" C (71.8° F) in July (Knight et al. 1987). Spring and early summer rainfall accounts for two-thirds of the annual precipitation, the balance coming as snow (Knight et al. 1987). METHODS We conducted our surveys on 20-24 May, 9-13 June, and 23-29 June 1991. In 1990, spring and early summer moisture was average or above average, resulting in a generally good flowering year for most species (Dean Culwell, personal communication). In 1991, there were heavy rains in April, May and June. This above-average precipitation directly following a good year produced an exceptional flowering year for most species. We believe that the.se conditions allowed us to make a good evaluation of the abundance of species of interest. We conducted our surveys by walking through an area, moving between canyon bottoms and ridges as much as possible. The study area is large and could not be surveyed entirely and evenly during the time allotted. Thus, we chose to stratify our surveys, giving preference to areas with high topographic and edaphic diversity (Gillison and Brewer 1985). We concentrated our efforts .south of the Pryor Mountains in the drainage of the Bighorn River (townships 25, 26, 27, 28). This area is highly dissected with many different soil types. The area west of the mountains in the drainage of the Clarks Fork of the Yellowstone River is a series of parallel valleys with sandy clay and silty soils. We surveyed portions of many of these valleys and found them relatively homogeneous. Most areas were visited only once during the study; however, we did return to areas with exceptional diversity. A map showing the locations of our sur\'eys is in Figure 2. We located populations of target species on USGS 7.5' topographic maps and recorded the dominant plant species in the immediate area for each population. We used the "feel" method to determine the textural class of the soil (Brady 1974). We also estimated the density of target species plants in 0.5-hectare plots by assigning them into one of three classes: (1) MOO, (2) 101-1000, and (3) >1000. In this way we obtained estimates of density, soil texture, elevation and vegetation for each population. We recorded only one population of each target species in each quarter-section. RESULTS We searched for and recorded information on 35 species of rare plants that were previously known from the Pryor Mountain Desert area. In addition, we discovered six rare species previously unknown from the area, including four species not previously known from Montana. One species, Eriogonum lagopus, is a candidate for listing as a threatened or endangered species by the U.S. Fish and Wildlife Service. A list of these species is provided in Table 1. A list of all vascular plant species encountered in the study area is in Appendix A. We located populations of all but one of the rare species that had previously been found in the area. Although we examined many specimens of Delphinium in the field, we were unable to locate any populations of D. geyeri. Distribution maps for each species are in Appendix B. Information on location, elevation, vegetation, soil texture and plant density for each population of each species is in Appendix C. The results of our surveys are summarized by species in the following section. The Natural Heritage Program status for each species reflects the most current knowledge, including the results of this survey. The Montana status is taken from Lesica and Shelly (1991) and does not reflect the results of this study. The Montana State Office of the Bureau of Land Management is currently in the process of estabUshing a species of special status program (J. Kwiatkowski, personal communication). Species with special status will be given special management considerations. We believe that species that are widespread in the study area with high densities in some parts of the study area should not be given special status by the Bureau of Land Management. These species generally have a revised Heritage Program status of S3. Only species with a very limited distribution or with predominantly low densities in the study area (SI or S2) should be given special status.

It is the dominant species in two plant associations. It occurs with Atriplex gardneri in saline clay soils and with Artemisia tridentata, Chrysothamnus nauseosus and Agropvron spicatum in sandy clay soils. MANAGEMENT RECOMMENDATIONS: Artemi.sia pedatifida has a limited distribution in Montana, but it is abundant within this small range. It should not be given special status on BLM's Miles City District. Artemisia spinescens D.C. Eat. Bud Sagebrush, Spring Sagebrush NATURAL HERITAGE PROGRAM STATUS: None MONTANA STATUS: None GLOBAL DISTRIBUTION: Oregon to Montana, south to California and New Mexico MONTANA DISTRIBUTION: Southern Carbon and Beaverhead counties PRYOR MOUNTAINS DESERT DIS TRIBUTION: Artemisia spinescens is locally common below 1525 m (5000 ft) on the south side of the Pr}'or Mountains. It generally occurs in sandy soil of alluvial plains, usually with A. tridentata. Atriplex gardneri or A, confertifolia. It is abundant only on s(5ils developed from Chugwater sandstone. • MANAGEMENT RECOMMENDATIONS: Tliis species is widespread and fairly common in the study area. It is probably not sensitive to livestock grazing. Artemisia spinescens should not be given special status on the BLM's Miles City District. Astragalus chamaeleiice Gray Cicada Milkvetch, Ground Milkvetch NATURAL HERITAGE PROGRAM STATUS: G5/S3 MONTANA STATUS: Threatened GLOBAL DISTRIBUTION: South-central Montana, south to Utah, Wyoming and Colorado MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: Astragalus chamaeleuce is widespread below 1555 m (5100 ft) south of the Pryor Mountains; however, populations are generally small and sparse (usually fewer than 100 plants). The species occurs in sandy, silty or sandy clay soils principally in plant associations dominated by Artemisia tridentata. although a few populations occur in Utah juniper open woodland. MANAGEMENT RECOMMENDATIONS: Although A, chamaeleuce is uncommon in the Pryor Mountain Desert due to the low density of plants, there is no evidence that it is sensitive to grazing, and it is widespread enough that other management activities could impact only a small proportion of the total population in the study area. It should not be given special status on BLM's Miles City District. Astrngaliis geycri Gray Geyer's Milkvetch NATURAL HERITAGE PROGRAM STATUS: G5/S2 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Southeast Oregon to California, east through southern Idaho to Montana, Wyoming, Utah and Colorado. MONTANA DISTRIBUTION: Daw.son, Garfield and Carbon counties 10 PRYOR MOUNTAINS DESERT DISTRIBUTION: Astragalus geyeri is local and uncommon to abundant below 1525 m (5000 ft) on the south side of the Pryor Mountains. We located seven populations; most were of small or moderate size and occurred in sandy soils of alluvial plains and terraces, usually with Artemisia tridentata. Stipa cdmata and Bouteloua gracilis. MANAGEMENT RECOMMENDATIONS: Astragalus geyeri is uncommon or perhaps even rare in the study area. This species is an annual, so population sizes are expected to fluctuate. It can probably tolerate moderate levels of disturbance but may be threatened by encroachment by exotic annuals such as Halogeton glome rat us or Salsola kali. Astragalus geyeri should be given special status on BLM's Miles City District. Astragalus gnui Parry Gray's Milkvctch NATURAL HERITAGE PROGRAM STATUS: G3-G4/S1 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Western Wyoming and adjacent Carbon County, Montana MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: Astragalus gravi is local and uncommon to common below 1370 m (4500 ft) on the west side of the Pryor Mountains in secondary drainages of the Clarks Fork of the Yellowstone River. We located four populations during our study; three of these were small. The species spreads by rhizomes and occurs in silty or clay soils with Artemisia tridentata, A. pedatifida and Agropyron spicatum. MANAGEMENT RECOMMENDATIONS: Astragalus grayi is rare in the study area and Montana; only two large populations are known. The effects of livestock grazing on this species are unknown. Populations may be threatened by road construction and oihei developments. This species should be given special status on BLM's Miles City District. 11 Astragalus hyalimis Jones Summer Orophaca NATURAL HERITAGE PROGRAM STATUS: G4/S3 MONTANA STATUS: Limited Distribution GLOBAL DISTRIBUTION: South-central Montana and western South Dakota, south to northeast Colorado and western Nebraska MONTANA DISTRIBUTION: Southern Carbon and Big Horn counties PRYOR MOUNTAINS DESERT DISTRIBUTION: Astragalus hyalinus is abundant below 1675 m (5500 ft) south and west of the Pryor Mountains in the drainages of the Bighorn and Clarks Fork of the Yellowstone rivers. We located 52 populations of A, hyalinus, occurring on barren sandy to clay soils in many plant associations including Utah juniper woodlands, sagebrush steppe and cushion plant-grasslands. Most populations were large. MANAGEMENT RECOMMENDATIONS: This species is common throughout much of the study area. Its cushion-plant growth form makes it resistant to livestock grazing. Astragalus hyalinus should not be given special status on BLM's Miles City District. Astragalus oregaiuis Nuttall Wind River Milkvetch NATURAL HERITAGE PROGRAM STATUS: G3-G4/S1 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Western Wyoming and adjacent south-central Montana MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: Astragalus oreganus is locally common, known from only four locations on the south side of the Pryor Mountains. Thi rhizomatous species forms large colonies in sandy soil below 1525 m (5000 ft) and is commonly associated with Artemisia tridentata and Stipa comata. 12 MANAGEMENT RECOMMENDATIONS: Although known populations are large, A, F oreganus is rare in the study area and Montana. Effects of livestock grazing are unknown. This species should receive special status on BLM's Miles City District. Camissonia andina (Nuttall) Raven Obscure Evening-primrose NATURAL HERITAGE PROGRAM STATUS: G4/S2 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Southern British Columbia to Alberta, south to California. Nevada and Wyoming MONTANA DISTRIBUTION: Carbon and Missoula counties PRYOR MOUNTAINS DESERT DISTRIBUTION: Camissonia andina is local and rare to common from 1220 to 1890 m (4000 to 6200 ft) on the south side of the Pr>'or Mountains and in the foothills. Six populations of C andina were located in the study area, and only two of these were large. It occurs in sandy soil and is usually associated with shrubs such as Artemisia tridentata and Cercocarpus ledifolius. One population occurred in Douglas fir-Utah juniper woodland. MANAGEMENT RECOMMENDATIONS: Camissonia andina is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. This species is uncommon in the study area; the majority of known populations were small. It should receive special status on BLM's Miles City District. Camissonia minor (\. Nelson) Raven Small-Howered Evening-primrose NATURAL HERITAGE PROGRAM STATUS: G4/S2 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Eastern Washington to eastern Montana, south to California, Nevada and Colorado MONTANA DISTRIBUTION: Carbon and Rosebud counties 13 PRYOR MOUNTAINS DESERT DISTRIBUTION: Camissonia minor is locally common below 1585 m (5200 ft) on the south side of the Pryor Mountains. It generally occurs in moderate-size populations in sandy soil of juniper woodlands or plant associations dominated by Artemisia tridentata. MANAGEMENT RECOMMENDATIONS: Camissonia andina is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. This species is common in the study area; we located 17 populations. This species should not be given special status on BLM's Miles City District. Camissonia parvula (Nuttall) Raven Small Evening-primrose NATURAL HERITAGE PROGRAM STATUS: G5/S1 MONTANA STATUS: None GLOBAL DISTRIBUTION: Eastern Washington to south-central Montana, south to California, Nevada and Colorado MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: Two small populations of Camissonia parvula were located at the southern foot of the Pryor Mountains between 1585 and 1675 m (5200 and 5500 ft). It occurs in sandy soil weathered from calcareous sandstone and is associated with ecotonal areas between juniper woodland and sagebrush steppe. MANAGEMENT RECOMMENDATIONS: Camissonia parvula is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. This species was first discovered in Montana during the course of this study. It is rare in the study area and should be given special status on BLM's Miles City District. 14 Camissonia scapoidea (T. & G.) Raven Naked-stemmed E\'ening-primrose NATURAL HERITAGE PROGRAM STATUS: G5/S3 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Eastern Oregon to south-central Montana, south to California, Arizona and New Mexico MONTANA DISTRIBUTION: Carbon, Choteau and Fergus counties PRYOR MOUNTAINS DESERT DISTRIBUTION: Cainissonia scapoidea is abundant below 1525 m (5000 ft) on the south and west sides of the Pryor Mountains in drainages of the Bighorn and Clarks Fork of the Yellowstone rivers. It occurs in sandy to clay soils in many plant associations, including juniper woodlands and shrublands dominated by Artemisia tridentata, Chrvsothamnus nauseosus and Atriplex gardneri. MANAGEMENT RECOMMENDATIONS: Camissonia scapoidea is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. This species is very common throughout the study area; more than 35 populations were located during the course of this study. It should not be given special status on BLM's Miles City District. Castilleia anmistiroiia (Nuttall) G. Don Narrow-lc;ived Paintbrush NATURAL HERITAGE PROGRAM Si ATUS: G5/S3 MONTANA STATUS: Limited Distribution GLOBAL DISTRIBUTION: Southeast Oregon lo southern Montana, south to Nevada. Utah and Wyoming MONTANA DISTRIBUTION: Beaverhead and Carbon counties PRYOR MOUNTAINS DESERT DISTKIBU TION: Castilleia antiustifolia is common and widespread through(nit the foothills and desert areas below 1830 m (6000 ft) both south and west of the Pryor Mountains. Sinall to large populations occur on sandy or sandy clay soils in juniper woodlands or. more ol'len, in plant associations dominated b\ Artemisia tridentata or A. arbuscula. 15 COMMENTS: Castilleja angiistifolia is closely related to C chromosa: the two taxa are separated on the color of the inflorescence (Welsh et al. 1987), and the latter is sometimes treated as a variety of the former (Dorn 1988, Holmgren 1984). Both taxa are reported for Montana. Stanley Welsh identified all of our collections as C angiistifolia. MANAGEMENT RECOMMENDATIONS: Nearly 30 populations of C angustifolia were located during this study. The species is common throughout most of the area and should not be given special status on BLM's Miles City District. Cleomc lutea Hook. Yellow Bee-plant NATURAL HERITAGE PROGRAM STATUS: G5/S1 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Eastern Washington to southern Montana, south to California, New Mexico and Nebraska MONTANA DISTRIBUTION: Southern Big Horn and Carbon counties PRYOR MOUNTAINS DESERT DISTRIBUTION: Cleome lutea is rare on the south side of the Pryor Mountains below 1525 m (5000 ft). It has also been collected on the northeast side of the mountains outside of our study area. The one small population located during our study occurred on sandy soil in juniper woodland. MANAGEMENT RECOMMENDATIONS: Cleome lutea is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. This species is often a roadside weed in the center of its range. However, it appears to be ver)' rare in the study area and should be given special status on BLM's Miles City District. Crvptanthn can a (A. Nelson) Payson Wooly Cr)ptantha NATURAL HERITAGE PROGRAM STATUS: G5/S3 MONTANA STATUS: Limited Distribution 16 GLOBAL DISTRIBUTION: Southern Montana and adjacent South Dakota, south to Nebraska and Colorado MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: Cryptantha cana is widespread and abundant below 1585 m (5200 ft) on the south side of the Pr)'or Mountains. It occurs in large populations in shallow sandy soils, mainly in plant associations dominated by cushion plants, Agropyron spicatum, Gutierrezia sarothrae and Ceratoides lanata. MANAGEMENT RECOMMENDATIONS: Cryptantha cana is very common in the study area. It is probably not sensitive to livestock grazing due to its cushion growth form. This species should not be given special status on BLM's Miles City District. Cryptantha flnvocuinta (A. Nelson) Payson Pale Yellow Cryptantha NATURAL HERITAGE PROGRAM STATUS: G5/S3 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: South-central Montana south to California and New Mexico MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: Cryptantha flavoculata is common between 1370 and 1830 m (4500 and 6000 ft) in the foothills on the south side of the Pryor Mountains. We located 19 populations, many of which were large. It is usually found in sandy calcareous soils in juniper woodlands. MANAGEMENT RECOMMENDATIONS: Cryptantha flavoculata is common in the study area. It is probably not sensitive to livestock grazing due to its bristly vesture. This species should not be given special status on BLM's Miles City District. 17 Crvptantha scoparia A. Nelson Desert Cryptantha NATURAL HERITAGE PROGRAM STATUS: G5/S1 MONTANA STATUS: None GLOBAL DISTRIBUTION: Eastern Washington to south-central Montana, south to Nevada, Utah and Wyoming MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: We discovered only one population of Crvptantha scoparia in the study area. This was the first collection of this species from Montana. It occurs in sandy soil at ca. 1370 m (4500 ft) on the south side the Pryor Mountains. The dominant species at this site were Artemisia tridentata and Agropvron spicatum. MANAGEMENT RECOMMENDATIONS: Crvptantha scoparia is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. This species is rare in the study area and in Montana, and should be given special status on BLM's Miles City District. Delphinium andcrsonii Gray Anderson's Larkspur NATURAL HERITAGE PROGRAM STATUS: G5/S1 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Eastern Oregon to south-central Montana, south to California, Nevada and Utah MONTANA DISTRIBUTION: Beaverhead, Carbon and Jefferson counties PRYOR MOUNTAINS DESERT DISTRIBUTION: We located only two small populations of D. andersonii on the west side of the Pryor Mountains in the Bridger Creek and Jack Creek drainages. It is found in sparsely vegetated, sandy, probably calcareous, soils at 1250-1310 m (4100-4300 ft). It is associated with communities dominated by Pinus flexilis, Juniperus spp. and Agropyron spicatum. 18 COMMENTS: Delphinium andersonii is very similar in appearance to the more common D^ bicolor; however, the former has glabrous herbage with upper petals that are white with blue tips, while the latter is puberulent with blue veins on the upper petals. The habitat of D. andersonii is often more xeric and barren. MANAGEMENT RECOMMENDATIONS: Delphinium andersonii appears to be rare in Montana and the Pryor Mountain Desert. Populations are small with scattered individuals. Members of this genus are poisonous to livestock and usually do not decline under livestock grazing. Since the plant is so similar to the more common D. bicolor. we may have failed to note all populations encountered. Further survey work is needed to determine the plant's distribution with certainty. Until such surveys have been completed, D. andersonii should be given special status on BLM's Miles City District. Delphinium geycri Greene Geyer's Larkspur NATURAL HERITAGE PROGRAM STATUS: G5/S1 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Southern Montana south to Nebraska, Colorado and Utah MONTANA DISTRIBUTION: Beaverhead and Carbon counties PRYOR MOUNTAINS DESERT DISTRIBUTION: We were unable to locate any populations of Delphinium geyeri in the study area. There is one collection from along the Bighorn River just south of the confluence with Dry Head Creek. Only 12 plants were observed in 1967 when the collection was made. MANAGEMENT RECOMMENDATIONS: Delphinium geveri appears to be rare in the study area and Montana. It should be given special status on BLM's Miles City District. Erigeron allocotus Hiakc Bighorn Fleabane NATURAL HERITAGE PROGRAM STATUS: G3/S3 MONTANA STATUS: Watch List 19 GLOBAL DISTRIBUTION: North-central Wyoming and adjacent south-central Montana MONTANA DISTRIBUTION: Southern Big Horn and Carbon counties PRYOR MOUNTAINS DESERT DISTRIBUTION: Erigeron allocotus is widespread and uncommon to abundant between 1525 and 2315 m (5000 and 7600 ft) on the south slopes of the Pryor Mountains. We located 17 populations in shallow limestone-derived soil in juniper woodland and plant associations dominated by Cercocarpus ledifolius. Artemisia arbuscula and Phlox spp. MANAGEMENT RECOMMENDATIONS: Erigeron allocotus is common on limestone at mid-elevations in the Pryor Mountains. Many of the sites where it is found are not subject to livestock grazing. This species should not be given special status on BLM's Miles City District. Eriogonnni X laoopiis Rydberg Rabbit Buckwheat NATURAL HERITAGE PROGRAM S TATUS: G3/S3 MONTANA STATUS: Limited Distribution GLOBAL DISTRIBUTION: South-central Montana and adjacent Wyoming MONTANA DISTRIBUTION: Southern Carbon County and reported from Park and Yellowstone counties. PRYOR MOUNTAINS DESERT DISTRIBUTION: Eriogonum lagopus is abundant between 1220 and 1675 m (4000 and 5500 ft) on the south and west sides of the Pryor Mountains. Large populations occur in barren sandy to clay soils in a number of plant associations, including juniper woodland, sagebrush steppe and, most commonly, cushion plant communities dominated by Agrc^pyron spicatum, Ceratoides lanata and Phlox spp. COMMENTS: Eriogonum lagopus is thought to be a fertile hybrid between E, brevicaule and E, paucitlorum (James Reveal, personal communication). Other authorities treat such hybrids as varieties of E, brevicaule (Welsh et al. 1987). Robert Dorn calls this plant E, brevicaule var. canum (Stokes) Dorn (Dorn 1988). Eriogonum lagopus is a candiiiate for listing as a threatened or endangered species under the Federal Endangered Species Act (USDl-FWS 1990). 20 MANAGEMENT RECOMMENDATIONS: Wc located 40 populations of R lagopus in the study area. The species has a wide ecological amplitude and occurs in a variety of open habitats. It should not be given special status on BLM lands in the Miles City District. Eriogoniim snlsiiuinnsum (Nuttall) Hook. Smooth Buckwheat NATURAL HERITAGE PROGRAM STATUS: G5/S1 MONTANA STATUS: None GLOBAL DISTRIBUTION: South-central Montana south to Nevada, Arizona and New Mexico MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: We located only one population of Eriogonum salsuginosum during the course of our study. This was the first collection of the species from Montana. It occurs in bentonitic soil at ca. 1430 m (4700 ft) on the south side of the Pryor Mountains. Associated species include M(^nolepis nuttalliana and Musineon divaricatum. COMMENTS: Some authorities consider the correct name for this species to be Stenogonum salsuginosum Nuttall. MANAGEMENT RECOMMENDATIONS: Eriogonum salsuginosum is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. There is a good deal of bcntonite mining in the immediate area; thus, strip mining may be a threat to the only known population of this species. Eriogonum salsuginosum is rare in the study area and Montana and should be gi\'en special status on BLM's Miles City District. Gilia inconspiciia (Sm.) Sw. Shy Gilia NATURAL HERITAGE PROGRAM S TATUS: G5/S3 MONTANA STATUS: Sensitive 21 GLOBAL DISTRIBUTION: Central Washington to south-central Montana, south to California and New Mexico MONTANA DISTRIBUTION: Beaverhead and Carbon counties PRYOR MOUNTAINS DESERT DISTRIBUTION: Cilia inconspicua is locally common below 1675 m (5500 ft) on the south and west sides of the Pryor Mountains in the drainages of the Bighorn and Clarks Fork of the Yellowstone rivers. We located 23, mainly moderate to large populations in sandy soils of juniper woodlands and associations dominated by Artemisia tridentata. COMMENTS: Montana plants are var. tweedyi (Rydb.) Cronq. Other authors have considered the correct name to be G. tweedyi Rydb. or G. sinuata Dougl. MANAGEMENT RECOMMENDATIONS: Cilia inconspicua is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. The species is common in the study area and should not be given special status on BLM's Miles City District. Giiia leptomeria Gray Great Basin Cilia, Sand Gilia NATURAL HERITAGE PROGRAM STATUS: G5/S2 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Central Washington to south-central Montana, south to California and New Mexico MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: Gijia leptomeria is locally common below 1675 m (5500 ft) on the south and west sides of the Pryor Mountains. Most populations are moderate to large and occur in sandy soil in Utah juniper woodlands and associations dominated by Artemisia tridentata. MANAGEMENT RECOMMENDATIONS: Gilia leptomeria is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. We located 12 populations of G^ leptomeria. The plant is common and widespread enough in the study area that it should not be given special status on BLM's Miles City District. Gravia spinosa (Hook.) Moq. Spiny Hcipsage NATURAL HERITAGE PROGRAM STATUS: G5/S2 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Central Washington to south-central Montana, south to California, Arizona and New Mexico MONTANA DISTRIBUTION: Beaverhead, Big Horn, Carbon and Park counties PRYOR MOUNTAINS DESERT DISTRIBUTION: Gravia spinosa is local and uncommon below 1525 m (5000 ft) on the south side of the Prj'or Mountains. Small populations occur in sandy soil in plant associations dominated by Artemisia tridentata. Stipa comata and Agropvron spicatum. MANAGEMENT RECOMMENDATIONS: We located only nine populations of a spinosa in the study area, and the majority of these were small. The species is highly palatable to livestock (Welsh et al. 1987) and may decrease with heavy grazing pressure. Gravia spinosa should receive special status on BLM's Miles City District.

Moderate to large populations are found in sandy soil of plant associations dominated by Artemisia tridentata and Atriplex gardneri. COMMENTS: Some authorities consider the correct name for this species to be Gilia pumila Nuttall. MANAGEMENT RECOMMENDATIONS: This species is an annual; thus, population sizes may very greatly among years and may respond positively to moderate levels of disturbance. We located 30 populations of I. pumila in the study area. The species is common over large areas and should not be given special status on BLM's Miles City District. Leptodactvlon caespitosum Nuttall Tufted Leptodactylon, Tufted Prickly Phlox NATURAL HERITAGE PROGRA.M STATUS: G3-G4/S2 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: South-central Montana, south to Nebraska, Colorado, Utah and Nevada 24 MONTANA DISTRIBUTION: Southern Carbcin County PRYOR MOUNTAINS DESERT DISTRIBUTION: Leptodactvlon caespitosum is local below 1525 m (5000 ft) on the south side of the Pryor Mountains. The species appears to be confined to outcroppings of Chugwater sandstone, generally with north or east exposures. Small to sometimes large populations occur in sparsely vegetated communities, often dominated by Chrysothamnus nauseosus and Phlox muscoides. COMMENTS: Welsh et al. (1987) state that L, caespitosum has a disjunct distribution due to its occurrence in peculiar soils. MANAGEMENT RECOMMENDATIONS: We located 11 populations of L caespitosum in the study area, but seven of these had less than 100 plants, and only two populations had more than 1000 plants. Populations are confined to an unusual although locally common substrate over an area smaller in size than a single township. These are the only populations known in Montana. Leptodactvlon caespitosum should be given special status on BLM's Miles City District.

MANAGEMENT RECOMMENDATIONS: Streptanthella longirostris is an annual; thus, population sizes may very greatly among years and may respond positively to 30 moderate levels of disturbance. We located 16 populations during our study. Although I many of these were small, the species occurs in two very widespread community types. This species should not be given special status on BLM's Miles City District. TownsencUa incann Nuttall Hoary Townsendia NATURAL HERITAGE PROGRAM STATUS: G5/S3 MONTANA STATUS; Sensitive GLOBAL DISTRIBUTION: South-central Montana to Nevada, south to Arizona and New Mexico MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DISTRIBUTION: Townsendia in can a is common below 1375 m (5500 ft) on the south side of the Pryor Mountains. It occurs in sandy soil of juniper woodlands but mainly associations dominated by Artemisia tridentata. Stipa comata and Bouteloua gracilis. MANAGEMENT RECOMMENDATIONS: We obsei^ed 21 populations of T. incana in the study area, and most populations were of small to moderate size. Although plants are often sparsely distributed in populations, the species is widespread in the study area, occurring in two of the most common plant associations. The plant's low cushion-like growth form curtails damage from grazing. It should not be given special status on BLM's Miles City District. Townsendia spathuhita Nuttall Sword Townsendia, Spoon-leaved Townsendia NATURAL HERITAGE PROGRAM STATUS: G4/S3 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: Southern Montana and central Wyoming MONTANA DISTRIBUTION: Beaverhead, Broadwater and Carbon counties 31 PRYOR MOUNTAINS DESERT DISTRIBUTION: Townsendia spathulata is common between 1220 and 2440 m (4000 and 8000 ft) in the Pryor Mountains and adjacent plains on the south side. The species is widespread in shallow, sandy, especially limestone- derived soils in mountain mahogany woodlands and cushion plant grasslands dominated by Agropyron spicatum, Ceratoides lanatus and Phlox spp. MANAGEMENT RECOMMENDATIONS: Plants are sparsely distributed within populations but the species is very widespread in the study area. We recorded 28 populations. The plant's low cushion-like growth form curtails damage from grazing. Townsendia spathulata should not be given special status on BLM's Miles City District. Wyethia scabra Hook. Rough Mule's-ears NATURAL HERITAGE PROGRAM STATUS: G5/S3 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: South-centr;il Montana south to Colorado, Utah and Arizona MONTANA DISTRIBUTION: Southern Carbon and Big Horn counties PRYOR MOUNTAINS DESERT DISTRIBUTION: Wyethia scabra is sparsely distributed but widespread below 1585 m (5200 ft) on the south side of the Pr>'or Mountains. It occurs in barren, sandy, usually shallow soil in sparsely-vegetated juniper woodlands and cushion plant grasslands dominated by Gutierrezia sarothrae, Chrysothamnus nauseosus and Phlox spp. MANAGEMENT RECOMMENDATIONS: We located 21 populations of W. scabra in the study area. Most populations were small due to the sparse distribution of the plants across the landscape. However, the species is widespread, and the scabrous, resinous foliage is probably not very susceptible to grazing. Wyethia scabra should not be given special status on BLM's Miles City District. 32 Xylorhiza glabriuscnln Nuttall SmcKMh Wootly-aster NATURAL HERITAGE PROGRAM SI ATUS: G5/S3 MONTANA STATUS: Sensitive GLOBAL DISTRIBUTION: South-central Moniana and western South Dakota, south to Colorado and Utah MONTANA DISTRIBUTION: Southern Carbon County PRYOR MOUNTAINS DESERT DIS TRIBUTION: Xvlorhiza glahriuscula is common below 1525 m (5000 ft) on the south and svest side of the Pr\'or Mountains. It occurs in clay or sandy clay soils in plant associations dominated by Artemisia pedatifida. A, tridentata and Chrvs(nhamnus nauseosus. MANAGEMENT RECOMMENDATIONS: We located 26 populations of X, glahriuscula in the study area, and most ol these were large. This species can usually be found where soils are appropriate. It is common in the study area and should not be given special status on BLM's Miles City District. DISCUSSION Managcnu-nt Considerations Populations of rare plants in the Pryor Mountain Desert are threatened by (I) encroachment of exotic species, (2) livestock and feral horse grazing, (3) off-road vehicle use, and (4) oil and gas development. Halogeton gk^meratus is an Asian species that was introduced into arid western North America in 1934. It has since spread throughout much of the arid and semi-arid lands in the western U.S. It is poisonous lo livestock and outcompetes many native species by increasing the salinity of the soil (Sauer 1988). This plant has become locally common in the Pryor Mountain Desert resiion and may be able to displace native plants, especially annuals. Livestock grazing throughout most of the study area appeared to be light to moderate due to the lack of water developmenis. However, severe effects of overgrazing were apparent in areas near water, such as Gyp Springs and Bear Canyon. In these areas, populations of rare plants may be llireatened with extirpation by trampling and perhaps by increased erosion resulting from desiiuction of the fragile vegetation. 33 Damage due to feral horses was observed west of the mouth of Big Coulee. Steep slopes and banks had been severely terraced and destabilized. Both livestock and feral horse grazing increases the likelihood of exotic weed encroachment. At the present time there is relatively little off-road vehicle use in th'e Pryor Mountain Desert area. However, the topography and sparseness of the vegetation is suitable for this sort of recreation. If off-road vehicle use increases substantially, it could damage some populations of rare plants by disrupting plants, compacting soil, and increasing erosion. Bentonite claims have been made on public lands in the Pryor Mountain Desert area and some strip mining has occurred in just south of the border in Wyoming. Oil and gas development has occurred south and west of Warren. Drilling and the associated road-building and development could destroy populations of rare plants. Sensitive plant surxeys should be conducted in association with any proposed developments. Protecting Biological Diversity Species that are at risk due to their rarity or other aspects of their biology should be given high priority for protection (Jenkins 1981). Based on the results of our study, vascular plants of special concern and limited distribution in Montana occurring in the study area can be divided into two groups: (1) high priority - species that are rare in the study area and in Montana (15 species) and (2) low priority - species of limited distribution in Montana that are common in the study area (26 species). Our knowledge of the distribution of these species, especially high priority species, in the Pryor Mountain Desert can be used to identify areas that are critical for protecting the biological diversity of this northern outlier of intermountain desert vegetation. Although low-priority species ha\e little chance of becoming extirpated in the Pryor Mountain Desert region and should not he given special protection status, they can provide information on the occurrence of the unusual desert-like habitats in which they occur. Of the 26 low-priority species, Astragalus chamaeleuce. Camissonia minor, Cryptantha cana, Cryptantha flavoculata. Hrigeron allocotus, Streptanthella longirostris, Townsendia incana, Wvethia scabra are confined to the area on the south side of the Pryor Mountains in the Drainage of the Bighorn River (T9S R28E, 27E, 26E, 25E), while none are confined to the areas north and west of Warren in the drainage of the Clarks Fork of the Yellowstone. These results suggest that the area directly south of the Pryors contains important habitats not found in the rest of the study area. This effect may be due to greater topographic relief as well as the presence of calcareous sandstone and Chugwater sandstone not present elsewhere. One criterion for selecting a reserw is density of rare or endangered species (Margules and Usher 1981). We used tlu- geographic information system (GIS) to overlay the distribution maps of the 15 hiuh-priority species (Figure 3). The Gypsum Creek-Crooked Creek area (T9S R27E, \\h R2SB) stands out as having the highest concentration of high-priority species populations. Eight of the 15 high-priority species, Astragalus geyeri, Astragalus oreganus. Camissonia andina. Cleome lutea, Grayia spinosa. Leptodactylon caespitosum, Malacothrix torreyi and Mentzelia pumila, have known populations in this area. The Gypsum Creek-Crooked Creek area is 1250-1580 m (4100- 5200 ft) in elevation and contains soils derived from calcareous sandstone, Chugwater sandstone and limestone. Terrain varies from highly dissected foothills with deep canyons to broad alluvial valleys. The appreciable habitat diversity and the large number of populations of both high- and low-priority species make the Gypsum Creek-Crooked Creek area the best choice for a single reserve in the Pryor Mountain Desert. The seven high-priority species not represented in tiiis area occur in widely separated sites throughout the study area (Figure 3) and cannot be protected practically in large reserves. In addition to the many species o\' rare plants found in the Prj'or Mountain Desert, we believe that many of the plant communities are rare in Montana, and some may be globally unique. Data from our floristic study provide a basis for delineating special management areas for protecting the biological diversity of the area. However, we believe that classification and mapping of plant communities should also be completed in order to take into account elements of diversity other than plant species. Using GIS, maps locating rare plant communities could be overlain on the existing rare plant maps to better delineate the boundaries of special management areas. This integrated approach will provide an information base that allows managers to protect biological diversity on multiple-use lands. 35 LITERA'FURi: CITED Brady, N. C. 1974.
