The species1 known range extends from central Idaho to Jackson Hole, Wyoming, into Montana (Beaverhead and Madison counties) , Utah (Box Elder, Cache, Rich and Sanpete counties) , and northeast Oregon (Hitchcock et al. 1955, Welsh et al. 1987) . During field surveys conducted in 1991, seven new occurrences of C. subniveum were located, and additional subpopulations were added to three previously known locations. In addition, two more locations were entered from Montana Rare Plant Project (herbarium) data. This brings the total number of occurrences of C. subniveum in Montana to twelve; five in Madison County, and seven in Beaverhead County. Populations occur on lands managed by the Bureau of Land Management, Dillon Resource Area; U.S. Forest Service, Beaverhead National Forest; and on private lands. One factor controlling the distribution of Cirsium subniveum in Montana is its association with unstable rock and gravel slides. However, the species does not appear to be tied to a particular geologic parent material. In Montana, C. subniveum populations occur in Pseudotsuga menziesii/Festuca idahoensis and Pseudotsuaa menziesii/Juniperus communis habitat types as described by Pfister et al. (1977) . A number of the populations are in historic mining districts that have seen some renewed attention by geological interests in recent years. Land managers should take these sites into consideration whenever evaluating activities that might effect these populations. Only a portion of the potential habitat of C. subniveum could be surveyed in the time allowed. Further survey work in the Tendoy and Snowcrest ranges, and particularly in the Gravelly Range, may reveal that C. subniveum is more common in this portion of the state. Due to small population sizes and low densities, C. subniveum should remain on the U.S. Forest Service, Region 1 sensitive species list. II. SPECIES INFORMATION A. CLASSIFICATION 1. SCIENTIFIC NAME: Cirsium subniveum Rydb. 2. COMMON NAME: Jackson's Hole thistle. 3. FAMILY: Asteraceae (=Compositae, Sunflower Family) . 4. GENUS: According to Hitchcock et al. (1955), there are perhaps as many as 200 species of Cirsium native to the northern hemisphere, with about 50 native species occurring in North America. The genus Cirsium is most closely allied with the strictly Old World genus Carduus. Dorn (1984) lists 13 species of thistle for Montana, several of which are introduced. 5. SPECIES: Recently, there was some confusion in Montana of Cirsium subniveum with C. neomexicanum var. utahense. In 1988 a collection from French Creek (K. Scow and E. Darfler (s.n.). 1988, MONTU) was identified as C. neomexicanum var. utahense by G. Ownbey. This author made a second collection from the same site (Schassberger (405) . 1990, NY), which better fit the description of C. subniveum, and was identified as such by Dr. Arthur Cronquist (pers. coram. 1991) , New York Botanical Garden. The Scow and Darfler collection was subsequently sent to Brigham Young University, and annotated C. subniveum by Dr. S. L. Welsh. The closeness of these two easily confused taxa was noted by Cronquist who stated "this species differs from the probably closely related C. utahense chiefly in its smaller and apparently much fewer-flowered heads, and more northern and more montane distribution. Further study may show the two to be conspecif ic" (Hitchcock et al. 1955) . Moore and Frankton (1963) suggested that C. pulcherrimum and C. subniveum were perhaps conspecif ic, but were uncertain because of the advanced maturity and insect damage of the type specimen of C. subniveum. Gardner (1974) however, refutes this idea with morphological data from a study of the isotypes at Rocky Mountain herbarium, and karyological and chemical data from field collections. I Nonetheless, the difficulty with the type specimen remains as mentioned by Cronquist, and reiterated by Moore and Frankton (1963) : "The type of C. subniveum is more densely hairy than most of the specimens to which the name is here applied, and it is possible that our plants need another name" (Hitchcock et al. 1955) . Thus, there may be two taxa involved which both currently are called C. subniveum. B. PRESENT LEGAL OR OTHER FORMAL STATUS 1. FEDERAL STATUS a. U.S. FISH AND WILDLIFE SERVICE: No status. b. U.S. FOREST SERVICE: Cirsium subniveum is on the U.S. Forest Service, Region 1 list of sensitive species (U.S. Department of Agriculture 1991) . Objectives and policy of the U.S. Forest Service provide for the management and protection of sensitive species under sections 2670.22 and 2670.32 in the 1984 Forest Service Manual. Under these guidelines, the Forest Service is to (a) "maintain viable populations of all native species of plants" (2670.22), and (b) "avoid or minimize impacts to species whose viability has been identified as a concern" (2670.32.3) . 2. STATE: Prior to the 1991 field season, Cirsium subniveum was listed by the Montana Natural Heritage Program as "very rare and local within its range" (global rank G3G4) by the Montana Natural Heritage Program (Achuff 1991) . This species was also listed for the state as "critically imperiled in Montana because of rarity" (SI = 1-5 occurrences) . The current number of known populations within the state is twelve. There will be no change in this species' global rank, but the state rank will be revised to S2 (6-20 occurrences) "imperiled in Montana because of rarity" to reflect the results of the 1991 field surveys. C. DESCRIPTION 1. GENERAL NONTECHNICAL DESCRIPTION: This taprooted perennial member of the thistle genus (Sunflower Family) may grow to a height of 28 inches. The freely-branching, slender stems are covered with > long white hairs, while the leaves are sparse woolly-hairy. Leaf margins are coarsely lobed and like most thistles, spine tipped. Solitary flowering heads occur at the tips of branches, with each head containing 25-50 white to light pink, tubular flowers. Each head is also surrounded by a ring of green bracts (the involucre) tipped by yellow spines. The outer bracts are sharply spine-tipped, while the inner bracts are more lax. Cobwebby hairs connect alternate bracts, and cross over the bract in between to give a lace-like appearance to the involucre (adapted from Schassberger 1991) . 2. TECHNICAL DESCRIPTION: "Perennial from a taproot, 3-7 dm tall, freely branching, the stem crisp- villous to arachnoid-f loccose or rather thinly tomentose, often eventually glabrate; leaves rather thinly f loccose-tomentose beneath, greener and more glabrate above; heads terminating the branches; involucre mostly 17-25 mm high, more or less arachnoid-tomentose, its rather broad bracts contracted into erect or more spreading yellow spines 3-8 mm long, the innermost slender, but innocuous and somewhat twisted; flowers rather pale pink or purplish" (Hitchcock et al. 1955) . 3. LOCAL FIELD CHARACTERS: Cirsium subniveum differs from C. neomexicanum var. utahense in its smaller and apparently less numerous-flowered heads. Also, the bases of the leaves are decurrent in C. subniveum. and it has a more northern and montane distribution (Hitchcock et al. 1955, Welsh et al . 1987) . Cirsium subniveum is distinguished from other species in the genus found in Montana by a number of characters: the presence of long involucral bracts; leaves that are much reduced upward; decurrent wings of lower leaves that are usually longer than those of the uppermost leaves; and involucral bracts that are pubescent with cobwebby hairs that tend to connect alternate bracts, and cross over the bract between (Dorn 1984) . Due to a faulty camera, only a photograph of a head that contains aging flowers and developing achenes is found in Section VI, p. 36. D. GEOGRAPHICAL DISTRIBUTION 1. RANGE: Cirsium subniveum is known from central Idaho to Jackson Hole Wyoming, Montana (Beaverhead and Madison counties) , Utah (Box Elder, Cache, Rich and Sanpete counties) , and northeast Oregon (Hitchcock et al. 1955, Welsh et al. 1987) . 2. CURRENT SITES: In Montana, C. subniveum populations occur in the Tobacco Root Mountains (Stonewall Creek (009), Mill Creek (Oil), (012)) and in the Ruby Range (Laurin Canyon (001) of western Madison County. It is also known from southern Madison County, along the southeast edge of the Gravelly Range (West Fork Madison (004) and Hidden Lake (008)). In adjacent Beaverhead County, this species occurs along the southern flanks of the Gravelly Range (Elk Lake (002, (006), (007)). Finally, two sites are located on the southern flanks of the Pioneer Mountains near Argenta (French Creek (003) , Kelly Reservoir (010)), and one in the Tendoy Mountains (Big Sheep Creek (005)), also in Beaverhead County. The locations of the twelve currently known sites for C. subniveum in Montana are shown in Figure 1, p. 6. The legal descriptions, latitudes and longitudes, elevations, USGS topographic map names, and locations of the occurrences in Montana are found in the Element Occurrence records, pp. 16-27. Exact locations are shown on U.S.G.S. topographic maps pp. 28-35. 3. HISTORICAL SITES: None known. 4. UNVERIFIED/UNDOCUMENTED REPORTS: None. 5.

ASSOCIATED VEGETATION: In Montana, C. subniveum populations occur in Pseudotsuqa menziesii/Festuca idahoensis and Pseudotsuqa menziesii/Juniperus communis habitat types as described by Pfister et al. (1977) . Associated tree and plant species occurring at one or more sites with C. subniveum include: Abies lasiocarpa (subalpine fir) Pinus contorta (lodgepole pine) Populus tremuloides (quaking aspen) Pseudotsuqa menziesii (Douglas fir) Achillea millefolium (common yarrow) Agropyron spicatum (bluebunch wheatgrass) Amelanchier alnifolia (western serviceberry) Antennaria microphylla (rosy pussy-toes) Arabis holboellii (Holboell's rockcress) Arnica lonqifolia (longleaf arnica) Artemisia tridentata (big sagebrush) Artemisia friqida (fringed sagewort) Artemisia michauxiana (Michaux mugwort) Aquileqia f lavescens (yellow columbine) Bromus tectorum (cheatgrass) Chaenactis douglasii (hoary chaenactis) Chrysothamnus nauseosus (common rabbitbrush) Chrysothamnus viscidif lorus (green rabbitbrush) Carex f ilifolia (thread-leaved sedge) Elymus cinereus (basin wildrye) Fragaria vesca (woods strawberry) Hieracium cynoglossoides (houndstongue hawkweed) Juniperus communis (common juniper) Juniperus scopulorum (Rocky Mountain juniper) Mahonia repens (creeping Oregongrape) Penstemon cyaneus (dark-blue penstemon) Penstemon deustus (hot-rock penstemon) Phleum pratense (common timothy) Poa secunda (Sandberg's bluegrass) Polypodium vulqare (western polypody) Rubus idaeus (red raspberry) Rosa woodsii (woods rose) Sambucus cerulea (blue elderberry) Spiraea betulifolia (shiny-leaf spiraea) Stipa viridula (green needlegrass) Tetradymia canescens (gray horse-brush) In Utah, this species occurs in pinyon-juniper communities (Welsh 1987) . 2. TOPOGRAPHY: The Montana populations occur on all aspects, but are more often found on the warmer (east, south, west) aspects. Populations in Montana occur at elevations that range from ca. 6100 (1850 m) to 8500 ft (2550 m) . In Utah, the species occurs near 6300 ft (1890 m) in elevation (Welsh et al. 1987), while in Wyoming it occurs from 6160 ft. (1880 m) to 6850 ft. (2100 m) in elevation (Gardner 1974) . 3. SOIL RELATIONSHIPS: The French Creek population occurs in well drained, gravelly to cobbled soils derived from parent material of Devonian or Cambrian origin (Alt and Hyndman 1980) . The Elk Lake ( (002) , (006) , (007) ) , Hidden Lake (008) and West Fork Madison (004) populations occur on unstable gravel and rock slides derived from Huckleberry Ridge Tuff (Sonderegger et al. 1982) . The Big Sheep Creek (005) population occurs on talus and gravels derived from the Madison group, Mission and Lodgepole limestone formations (Scholten et al. 1955) . This information indicates that the distribution of Cirsium subniveum appears to be related to unstable rock and gravel slides, but it does not appear to be tied to a particular geologic parent material. 4. REGIONAL CLIMATE: Cirsium subniveum occurs in a region of Montana that has a very dry, continental climate. Much of the yearly precipitation falls as rain or wet snow in May and June, with large convective storms providing mid- and late summer moisture. Winters are cold and dry, with precipitation occurring mostly in the form of snow. The following data (Table 1, p. 9) come from long term (1951-1980) climatological stations (U.S. Department of Commerce 1982) . The nearest long term climatological station to C. subniveum populations on the east edge of the Ruby Mountain, and the south edge of the Tobacco Root Mountains is at Virginia City (elev. 5776 ft. (1760 m) ) . The station is approximately 13 miles east and 1025 ft (312 m) lower than the Laurin Canyon (001) population, and approximately 14 miles south and 1000-2000 ft. (300-600 m) lower than the Mill Creek (011, 012) and Stonewall Creek (009) populations. The nearest long term climatological station to the Gravelly Range populations is at Lake View (elev. 6710 ft. (2045 m) . This station is approximately 10 miles southwest, and 10-700 ft (3-200 m) lower than the Elk Lake (002,006,007) and Hidden Lake (008) populations. This station is also ca. 13 miles southwest and 600 ft. (180 m) higher than the West Fork Madison (004) population. Finally, the nearest long term climatological station to the French Creek (003) and Kelly Reservoir (010) C. subniveum populations is at Dillon (elev. 5228 ft. (1595 m) ) . The station is approximately 11 miles southeast, and 1500-1900 ft (450-570 m) lower than these populations. Table 1. Long term climatological data for Virginia City, Lakeview, and Dillon, Montana. weather station station elevation mean annual temperature mean maximum temperature in July mean minimum temperature in January mean annual precipitation Virginia City 5776 ft (1733 m) 42.4°F (5.7°C) 81.3°F (21.7°C) 10.6°F (-11.9°C) 16.26 in (40.5 cm) Lakeview 6710 ft (2010 m) 35.0°F (1.7°C) 76.5°F (24.9°C) 0.5°F (-17.6°C) Dillon 5228 ft (1565 m) 42.6°F (5.9°C) 83.3°F (28.7°C) 9.4°F (-12.7°C) 20.52 in (51.3 cm) 9.53 in (23.8 cm) Due to differences in elevation and geographic position between the Virginia City and Dillon stations and their associated populations, it is likely that the C. subniveum populations receive more precipitation than is listed for the station, F. POPULATION DEMOGRAPHY AND BIOLOGY 1. PHENOLOGY: This species flowers from early July through mid- to late August. Flowering heads may contain mature seeds as early as late July. This late flowering species may be restricted to higher elevation sites where moisture is available later into the summer months. 2. POPULATION SIZE AND CONDITION: Population sizes are small ranging from ca. 10 to 210 individuals. The area covered by populations ranges from ca. 1 10 to 60 acres. The total number of plants observed in Montana is ca. 816, distributed across on 140 acres. Although the populations appeared healthy, plant density is not high. Visits to the French Creek population in 1990 and 1991 revealed that one subpopulation present in 1990, was not present in 1991. It is possible that seedlings were overlooked at this site, or that weed control activities may have eliminated this subpopulation. Observations should be made in 1992 to confirm the absence of this subpopulation . 3. REPRODUCTIVE BIOLOGY a. TYPE OF REPRODUCTION: This tap-rooted perennial reproduces by way of seed. Chromosome counts revealed 2N = 34-36 for C. subniveum (Welsh et al. 1987) . b. POLLINATION BIOLOGY: Bees were observed pollinating Cirsium subniveum plants (pers. obs.), but other insects may also serve as pollinators. c. SEED DISPERSAL AND BIOLOGY: The wings on the seeds of species in the genus Cirsium aid in dispersal by wind. Dispersal usually occurs in late summer and early fall. POPULATION ECOLOGY 1. BIOLOGICAL INTERACTIONS a. COMPETITION: Cirsium subniveum occurs in habitats where competition is limited by harsh site conditions (loose gravelly scree) . The restriction of this species to these locations may be due to a lack of competitive ability. b. HERBIVORY: Native plants in the genus Cirsium support a variety of herbivorous fauna including weevils, and several species of moths (Turner et al. 1987a, 1987b) . In addition, young rosettes are grazed by sheep and cattle, but spines usually offer some protection to adult plants. In either case fecundity is likely to be lowered. 11 H.

THREATS TO CURRENTLY KNOWN POPULATIONS: 1. GRAZING: Young rosettes of species in the genus Cirsium are palatable to grazers, but adult flowering plants are often not preferred. Due to unpalatability, many introduced species of Cirsium are increasers with heavy grazing, but the effect on this native species is not known. 12 2. MINING: The French Creek (003), Mill Creek (Oil, 012) , and Stonewall Creek (009) populations occur in historic mining districts. Recently, these areas have received some renewed attention by geological interests. These populations should be considered in any proposed project activities that might affect these areas. 3. WEED CONTROL ACTIVITIES: Weed control activities could pose a problem especially to the roadside populations at Elk Lake (002), French Creek (003), Stonewall Creek (009), and Mill Creek (011, 012). Forest Service weed control managers should be made aware of population locations. B. MANAGEMENT PRACTICES AND RESPONSE: A weevil (Rhinocyllus conicus) introduced as a biological control for Carduus species (introduced Eurasian species) , has a high infestation rate in populations of the endemic thistle Cirsium longistvlum in the Little Belt Mountains of north-central Montana. The introduced weevil is lowering the fecundity of C. longistylum populations at an unknown rate. This same weevil is also known to infect a number of other thistles in California, including C. brevistylum, also a species of concern in Montana (Turner 1987b) . The possibility of infestation occurring with other native thistles including C. subniveum should be taken into account when considering the introduction of biological controls. C. RECOMMENDATIONS FOR MAINTAINING VIABLE POPULATIONS: It is recommended that managers be made aware of the C. subniveum populations with respect to any weed control activities. Also, this species should be considered when evaluating the impacts of proposed mining activities. D. RECOMMENDATIONS FOR FURTHER ASSESSMENT: Only a portion of the potential habitat of C. subniveum could be surveyed in the time allowed. Further survey work in the Tendoy and Snowcrest ranges, and particularly in the Gravelly Range, may reveal that C. subniveum is more common in this portion of the state. Due to small population sizes and low densities, C. subniveum should remain on the U.S. Forest Service Region 1 sensitive species list for the Beaverhead National Forest. 13 IV.
