I . INTRODUCTION

A sensitive plant survey of the Centennial Valley and Mountains was conducted during the summer of 1993. The primary purpose of this investigation was to determine the occurrence, frequency and distribution of the rare plant species considered potentially sensitive by the Bureau of Land Management (BLM) . This inventory of sensitive plants is a management tool for the BLM to revise the draft BLM list of sensitive plants in Montana and to implement a sensitive species program in the Centennial Valley.

The Centennial Valley has among the highest numbers of rare species of all BLM land areas in Montana. Although there had been no extensive systematic survey of BLM lands prior to this study, thirteen of the thirty-six known state species of concern in the Centennial Valley (Table 1) had been documented on BLM- administered lands at the start of this project based on such studies as represented in Dorn (1968) , Lowry (1979) , Lesica (1985), Schassberger (1988) and Heidel (1993).

II. STUDY AREA

The Centennial Mountains form much of the Continental Divide along the border between southwestern Montana and Idaho (Fig 1) . The Centennial Mountains are on of the few ranges in North America that run in an east-west direction. The mountains are bounded on the north by the Centennial Valley and on the south by the Snake River Plains. This area is represented by a wide range of floristic and vegetational diversity including: open sagebrush desert; open, rocky canyons and streambanks ; open, disturbed roadways and trails; dry, open grasslands; seasonally moist, montane coniferous forests; seasonally moist aspen groves; moist stream courses; montane and subalpine meadows and slopes; subalpine and alpine lakes; subalpine and alpine coniferous forests; alpine scree and talus slopes; meadows, grasslands, and windswept ridges; a wide range of wetland habitats including lakes, ponds, wet meadows, marshes, and seepage area; and sand dunes and hills (Lesica, 1984; Lowry, 1979).

The Centennial Valley is a high elevation (6600 feet) intermontane valley centered on the Red Rock River headwaters. The valley is located between 44^' 31' and 44" 40' latitude and 111° 40' and 112° 20' longitude (Figure 1). Centennial Valley is approximately 4 0 miles long and 7 miles wide, bordered on the northeast by the Gravelly Range and the Snowcrest Mountains to the northwest. The Centennial Mountains are oriented approximately in an east-west direction, forming the southside of Centennial Valley for 40 miles from Monida Pass, Montana to the Henry's Fork of the Snake River in Idaho. Mount Jefferson on the east side of the range is the highest point, reaching an elevation of 10,211 feet (MAPS 1990).

* This list represents a compilation of all state species of concern documented within the study area as of 24 March 1993, which were the primary target species for inventory. Those which had been documented on BLM lands prior to this study are marked by an asterisk (*) , and those species which were proposed for BLM status in Montana (sensitive or watch; BLM draft list of March 1993) are bold-faced.

In addition, five more rare species are reported from the area by various sources, with incomplete information: Allium acuminatum from the Centennials area by Lowry (1979), Castilleia gracillima from the Centennials area by Lowry (1979), Kobresia simpliciuscula from Odell Canyon by Lowry (1979), Pteryxia hendersonii (Cymopteris hendersonii) reported from Odell Canyon and Sheep Mountain - herbarium records needed from RM, and Stephanomeria spinosa from Red Rock Pass - source unknown.

The area's land ownership is divided between Bureau of Land Management, Red Rock Lakes National Wildlife Refuge, Beaverhead National Forest, Agricultural Research Service, State of Montana and private.

Throughout this report, "Centennial Valley" will be used to refer to the entire study area, which encompasses the Montana side of the Centennial Mountains, and the lower foothills of the Gravelly and Snowcrest Ranges.

Ownership within the study area is depicted on Figure 1, based on BLM digitized data, as updated by Department of State Lands in post-1982 corrections. The 1990 Southwestern Montana Interagency Map produced by the BLM was used to resolve disparities between the two preceding maps, unless map consultants responsible for these products directed otherwise.

Geology

The Centennial Mountains belong to the Laramide orogeny system and are included in the broader category of "Central Rockies" (Eardley 1951) . The mountains are tectonic in origin, arising from the prominent "Centennial Fault"; a fault block of east-west orientation that runs along the northern foot slope of the mountains. The Centennial Mountains to the south of the fault are the uplifted range-block and the Centennial Valley to the north is the down-thrown basin block, resulting in a 3,000 foot fault scarp. The uplift of the Centennial Range began in Lower Cretaceous time, which marked the advent of the Laramide orogeny, and continued to early Eocene time (Honkala 1960) .

The Centennial escarpment was further modified by glaciation during the Pinedale and Bull Lake stages (Taylor and Ashley 1990) . Small terminal moraines at the foot slope of the mountains are common as are small north-south trending glacial valleys and cirques. More recently, the scarp was modified by avalanches and landslides which are evident along the mountain sides.

The rocks comprising the Centennial Mountains are: 1. Precambrian metamorphics; 2. Paleozoic, Mesozoic, and Cenozoic sediments; and 3. Cenozoic volcanics. The watershed to the east which includes the Alaska Basin area and the Tom Creek drainage is comprised almost entirely of Precambrian metamorphosed carbonates (Taylor and Ashley 1990) .

Above the Precambrian metamorphics, at the headwater of Red Rock Creek and Tom Creek, sedimentary rocks prevail. Represented in these high altitude rocks are Cambrian rocks which are progressively overlain by sedimentaries of Devonian Jefferson Limestone or Three Forks Formation; Mississippian Madison Formation Limestone; Permian Phosphor ia Formation' Pennsylvanian Amsden and Quadrant Formation; and in some areas, Tertiary volcanics (Egbert 1960, Mann 1960, Taylor and Ashley 1990) . With the exception of the Phosphor ia Formation which contains cherts, shales, and phosphorite (Cressman and Swanson 1960) , the above strata are primarily composed of limestone, dolomite, and sandstones (Mann 1960) .

The continuity of the Centennial Mountains is disrupted by a north-south trending fault through the Odell Creek drainage. Honkala (1960) theorized that this is a high-angle normal fault. The area west of the fault is composed of Tertiary volcanics. Mount Baldy dominates the area at an elevation of 9889 feet.

The geologic composition of the Centennial Valley floor is Quaternary alluvium which resulted from the erosional breakdown of the surrounding mountains (Taylor and Ashley 1990) .

Climate

The Centennial Region is characterized by long cold winters and short cool summers. The average annual precipitation is 20 inches (1961-1991) .

Average snowfall during the winter months is 150 inches. Snowfall during every month of the year is not uncommon.

The mean annual temperature is 34.9 F. During extreme cold periods, air temperatures commonly drop to the -3 0°F to -4 0°F range. The summer maximum temperature rarely exceeds 90 F.

Although frost occasionally occurs during every month of the year, the average length of the frost-free season is approximately 51 days. This season extends from mid-June to mid- August (MAPS 1990) .

Soils

The soils of the western portion of the Centennial Mountains (east of Odell Creek) consist of rock outcrops and talus slopes at higher elevations and mollisols on the benches and terraces. The soils of the Centennial Mountains west of Odell Creek, north and south of the Red Rock River basin, are inceptisols-alf isols. The parent materials are colluvium, igneous rock, and sedimentary. The Red Rock River drainage contains characteristic mollisols from a cold, wet basin who are derived from the parent material alluvium. The soils surrounding the Lima Reservoir are aridisols-mollisols that are calcareous from the parent materials of alluvium and colluvium (MAPS 1990) .

Soils of the Centennial Valley are in the process of being mapped by the Soil Conservation Service (Gomez personal communication) .

Vegetation

Vegetation of the Centennial Mountains is diverse and varies with elevation, hydrology, substrate and microhabitat . It is predominately coniferous forest dominated by Douglas fir (Pseudotsuqa menziesii) and lodgepole pine fPinus contorta) . The streams and higher cool slopes are characterized by the spruce (Picea enqelmannii) and horsetail (Equisetum arvense) association (DeVelice 1992) . Whitebark pine (Pinus albicaulis) and subalpine fir (Abies lasiocarpa) dominate in the subalpine region with occasional stands of limber pine (Pinus flexilis) (DeVelice 1992) . The lower elevations along the foothills are dominated by big sagebrush (Artemisia tridentata) , three-part sagebrush (A. tripartita) and rabbit brush ( Chrysothamnus nauseosus) . The upper wetlands are dominated by shrubby cinquefoil (Potentilla fruticosa) and Idaho fescue (Festuca idahoensis) . The lower, wetter meadows are dominated by tufted hairgrass (Deschampsia cespitosa) , sedges (Carex spp.) and rushes ( Juncus spp. ) . The swamps and drainages are dominated by willows (Salix spp) . The Centennial Sandhills consist dominated by thickspike wheat grass (Agropyron dasystachyum) , silverleaf

phacelia (Phacelia hastata) , big sagebrush (Artemisia tridentata) , threetip sagebrush, (Artemisia tripartita) , Idaho fescue (Festuca idahoensis) (DeVelice 1992) .

Flora

A recent floristic inventory of the Centennial Mountains on BLM lands documented 3 62 taxa (including species, subspecies, and varieties) representing 190 genera in 43 families (Lowry 1979) , or approximately 15% of the flora of Montana (Shelley 1986) . Dorn (1968), in a more complete floristic study of the Red Rock Lakes National Wildlife Refuge and adjacent Centennial Mountains, listed 487 species in 243 genera and 65 families, or approximately 21% of Montana's flora (Shelley 1986) . Areas of such high floristic and geographic diversity often harbor numerous rare or unique species (Shelley 1986) . There are no taxa known to be strictly endemic to the Centennial Region, however a number of taxa occur there which are either regional endemics or which occur on the edge of their range (Shelley 1986) .

III. METHODS

The Centennial Valley and Mountains was surveyed on May 26- 31, June 18-3 0, July 1-28, and August 3-2 0 for state plant species of concern which have been documented from the Centennial Valley (Table 1) . The search routes for each of the target species were concentrated on BLM tracts with potential habitat, as determined from review of existing records in the Biological Conservation Database of the Montana Natural Heritage Program (MTHP) . I reviewed specimens of target species at the Montana State University (MSU) herbarium prior to the field season and outlined potential new sites evaluating soil and aerial maps of the study area. I conducted my surveys by hiking through each target area, inspecting typical habitat as well as unusual edaphic or topographic features. "Plant Species of Special Concern" survey forms were filled out upon location of a target plant (Appendix B) . Topographical maps were then marked with the population and photographs of the individual species and their habitat were taken.

Identification of collections was made following Dorn (1984) and Hitchcock and Cronquist (1973). More difficult determinations were made by using specimens in the MSU Herbarium for reference and consulting with Dr. J. Rumely. Voucher specimens are deposited at MSU Herbarium.

VI . RESULTS

The results from the sensitive plant species inventory yielded data that confirmed that the Centennial Valley is a highly diverse area. The data within Table 2 and presented in Figure 2 are a compilation of the rare flora that have been documented in Centennial Valley. The species information that follows represents detailed data gathered from BLM-administered land on the following plant species: Astragalus ceramicus var. apus. Carex vallicola. Cryptantha fendleri. Eriogonum ovalif olium var. nevadense. Ipomopsis congesta ssp. crebif olia . Penstemon whippleanus, Senecio debilis. Sphaeralcea munroana and Thelypodium sagittatum ssp sagittatum. In addition, Draba globosa was collected by a cooperating researcher, and sensitive plant survey forms were submitted by the author and a cooperating researcher on four additional state species of special concern after this report was conveyed in final form to the Montana Natural Heritage Program. The four additional species include Astragalus argophyllus var. argophyllus. Astragalus lentinginosus var. salinus. Astragalus terminalis and a new species addition to the state flora, Stellaria iamesiana. The results represent new information on fourteen species, with detailed treatment for the first nine.

In addition, there were previous documentations of the following plant species on BLM-administered land: Balsamorhiza macrophylla, Carex parryana ssp. idahoa, Elvmus flavescens. Gentiana aquatica. Oenothera pallida var. idahoensis and Thalictrum alpinum; for a total of twenty rare taxa documented on BLM lands. All new or revisited records and pre-existing records are depicted in Figure 2, pocket map.

Of the 39 Centennial Valley rare species, ten are recommended dropped from BLM proposed sensitive or watch consideration, but eleven are recommended for sensitive consideration and eleven for watch consideration.

The field season of 1993 was often interrupted due to unseasonally cool temperatures and high precipitation. These factors significantly influenced the extent of the area surveyed, which places even more importance on the high numbers of species documented in an abbreviated field season. The significant number of occurrences of rare plant species documented in a shortened field season, indicates a need for further survey work in the Centennial Valley to determine the extent of biodiversity in this region. These results strongly indicate that further survey work would reveal more element occurrences of rare plant species.

Results and recommendations based on this work are summarized on the Table 2 (next page) . Information on individual species follows alphabetically, beginning with nine species described in detail, followed by five species whose status in the Centennial Valley is briefly summarized based on information which came in late. Appendix B includes printouts of all species recommended for further consideration, and Appendix C includes maps of new or revisited records.

10 Astragalus ceramicus Sheld. var. apus Barneby I. SPECIES INFORMATION A. CLASSIFICATION

1. SCIENTIFIC NAME: Astragalus ceramicus var. apus

2. COMMON NAME: Painted milkvetch

3. FAMILY: Fabaceae

4. GENUS: According to Cronquist et.al. (1989), the genus Astragalus contains perhaps 1600 species, in number of taxa but not in biomass the largest of Leguminosae, dispersed primarily around the Northern Hemisphere, most highly diversified in arid continental, desert, and Mediterranean climates (An ancient Greek name for some leguminous plant, possibly from astragalos , ankle bone, in reference to the pod or leaf shape.)

5. SPECIES: Astragalus ceramicus var. apus is

found within sand dunes and sandy flats or draws at elevations of 1400-1500 m. It is locally abundant on the upper Snake River Plains in Idaho and in southwestern Montana (Cronquist et al. 1990) .

B. PRESENT LEGAL OR OTHER FORMAL STATUS

1. BUREAU OF LAND MANAGEMENT: Astragalus

ceramicus var. apus is proposed as a sensitive species for the Dillon Resource Area. No changes to BLM status are recommended based on this study.

2. STATE: Astragalus ceramicus var. apus is

currently recognized by the MTHP as "critically imperiled because of extreme rarity (5 or fewer occurrences, or very few remaining individuals) , or because of some factor of its biology making it especially vulnerable to extinction" (state rank = SI) . No changes to MTHP rank are recommended based on this study.

C. DESCRIPTION

1. GENERAL NONTECHNICAL DESCRIPTION: Astragalus ceramicus var. apus is a perennial plant with elongated stems and linear leaves. The distinctive pods are oblong and inflated, like a balloon, mottled with bright patches of purple.

11

2. TECHNICAL DESCRIPTION: Astragalus ceramicus var. apus is a finely strigillose, usually canescent perennial with a deep root and long slender filiform rootstocks, easily mistaken for an annual; stems 1-3 dm tall, flexuous and often zigzag; stipules linear- lanceolate, 3-8 mm. long, the lower ones usually very shortly connate, the lower ones free; leaflets mostly lacking, the rachis elongate and flexuous, 5-13 cm. long, occasionally with 1-several linear leaflets 1- 3.5 cm. long; racemes 3-10 flowered; peduncles much shorter than the leaves; pedicels 1-3 mm. long; flowers 6-9 mm. long; calyx about 4 mm. long, strigillose, often purplish mottled, the short auricles, little if any longer than the purplish- tipped keel; pod ordinarily stipitate but usually sessile, the body membranous, much inflated, purplish-mottled, oblong-ellipsoid, 2.5-3.5 cm. long, glabrous, l-celled, the lower suture often prominent but only very slightly if at all intruded.

3. LOCAL FIELD CHARACTERS: Astragalus ceramicus var. apus is easily recognized anytime during or after fruiting by its inflated pods that are purple mottled. The leaflets are long and slender, less than 3 mm wide.

D. GEOGRAPHICAL DISTRIBUTION

1. RANGE: Astragalus ceramicus var. apus is

found in sand dunes and prairie lands from central Idaho to southwestern Montana.

2. CURRENT SITES: Astragalus ceramicus var. apus is found within the sand dune region of Centennial Valley, located on the north side of Red Rock Lakes National Wildlife Refuge. This is the only place it is known from in Montana.

E. HABITAT

1. ASSOCIATED VEGETATION: Astragalus ceramicus var. apus is found in blowout area within sand dune regions. It is found in sandy, well drained soils with the following grasses and forbs accounting for 40-50% vegetative cover:

Artemisia tripartita (threetip sagebrush)

buckwheat) Cryptantha fendleri (Fendler cat's eye) Elymus flavescens (sand wildrye) Eriogonum ovalifolium var. nevadense (oval-leaved

buckwheat) Festuca idahoensis (Idaho fescue) Oenothera pallida var. idahoensis (pale evening

12

Phacelia hastata (whiteleaf phacelia)

primrose) Stipa comata (needle and thread grass) Tetradymia canescens (gray horsebrush)

2 . TOPOGRAPHY AND SOILS : Astragalus ceramicus var . apus is found on sandy well-drained soils in blowouts associated with sand dune areas. Individuals are located on open south and west facing slopes, at 6600 ft. elevation. The slopes are moderately steep (2 0- 30%) .

F. POPULATION DEMOGRAPHY AND BIOLOGY

1. POPULATION SIZE AND CONDITION: Astragalus ceramicus var. apus was reported in 1987 to have a well established large population (Schassberger , 1987) . However, I noted that there were few individuals (less than 100) and no large populations. I did not make an intensive survey of the area to confirm the decrease of individuals. There is no evidence to indicate that this taxon can go dormant over entire growing seasons, so these preliminary observations are taken to indicate a major population decline.

G. REPRODUCTIVE BIOLOGY: Astragalus ceramicus var. apus is a perennial that reproduces by seed.

H. LAND OWNERSHIP: Astragalus ceramicus var. apus occurs on BLM and private lands.

II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS

A. THREATS TO KNOWN POPULATIONS: Astragalus ceramicus var. apus occurs on the sand dune region in the Centennial Valley where there is light to moderate grazing pressure. In 1987 the populations were reported as thriving. However, in 1993 during the sensitive plant survey I observed only a few small populations. A possible factor is the livestock use in the area, as suggested by Schassberger (1988) .

B. FURTHER ASSESSMENT AND MANAGEMENT NEEDS: The decline in numbers warrants a study to determine the cause before future management decisions can be made.

C. SUMMARY: Astragalus ceramicus var. apus occurs in Montana in the sandy hills and plains of the Centennial Valley. The apparent population decline is a priority for sensitive species monitoring on lands administered by BLM and U.S. Fish and Wildlife Service. It is among the singular features of the Centennial Sandhills, an area which has been proposed for natural area recognition (Lesica, no date) .

Carex vallicola I. SPECIES INFORMATION

A. CLASSIFICATION

1. SCIENTIFIC NAME: Carex vallicola

2. COMMON NAME: Valley sedge

3. FAMILY: Cyperaceace

4. GENUS: According to Hermann (197 0) there are more than 600 species of Carex known to exist in North America, and the differences among them being often small though definite. The species of Carex are comparable to the grasses in forage value.

5. SPECIES: Carex vallicola has a forage value from fair to excellent, and in the Great Basin area particularly it is considered an important plant on the range. It is found on dry, open slopes and in clearings, chiefly at 6,000 to 8,000 feet.

B. PRESENT LEGAL OR OTHER FORMAL STATUS

1. BUREAU OF LAND MANAGEMENT: Further survey is

warranted before proposing any changes to BLM status or ruling it out.

2. STATE: Carex vallicola is defined as being imperiled because of rarity (6 to 2 0 occurrences) , or because of other factors demonstrably making it very vulnerable to extinction throughout its range (S2 = state ranking) . No changes to MTHP rank are recommended based on this study.

C. DESCRIPTION

1. GENERAL NONTECHNICAL DESCRIPTION: Carex vallicola can be readily distinguished in the field by the dorsal bulging of the mature perigynium, the distention being so pronounced that the resultant stretching of the perigynium walls displaces the thickened margins so that they run down the ventral surface of the perigynium.

2. TECHNICAL DESCRIPTION: Carex vallicola is caespitose from short-prolonged, fibrillose rootstocks; culms slender, 2-6 dm. high, roughened on the angles below the head; leaves about 3 to a culm, 1-1.5 mm. wide, thin, the sheaths light, thin ventrally, the ligule

14

very short, wider than long; spikes closely aggregated into a dense, terminal, oblong-linear head, 1.5-2.5 cm. long, 6-8 mm. wide, the staminate flowers terminal and inconspicuous; scales broadly triangular, shorter than the perigynia, hyaline with the centers brownish and one-three-nerved, acute to short-cuspidate; perigynia plano-convex, oblong- elliptic, 3.5-3.75 mm. long, 1.75-2.25 mm. wide, margined, greenish or brownish-tinged, nerveless ventrally, obscurely nerved dorsally, glossy at maturity, the margin more or less serrulate above, abruptly narrowed into a minutely serrulate beak about 1 mm. long, obliquely cut and only shallowly bidentulate; achenes lenticular, orbicular, substipitate, 2X2 mm.

3. LOCAL FIELD CHARACTERS: Carex vallicola is

29 Senecio debilis Nutt . I. SPECIES INFORMATION

A. CLASSIFICATION

1. SCIENTIFIC NAME: Senecio debilis

2. COMMON NAME: Rocky Mountain Ragwort

3. FAMILY: Asteraceae

4. GENUS: According to Hitchcock and Cronquist (1973) , the genus Senecio is one of the largest genera of plants, containing probably well over 1000 species, of very wide geographic distribution. Many of the species are closely related, often indeed, with only about the degree of distinctness more commonly associated with varieties. An attempt to reach a more conservative treatment frequently necessitates the inclusion of such a large number of highly diverse taxa within the limits of a single "species" as to be wholly impractical. (Name from the Latin senex, an old man, probably referring to the white pappus or hoary pubescence of some species.)

5. SPECIES: Senecio debilis occurs in moist open meadows, especially in alkaline situations; northern Colorado northwestward through Wyoming to southwestern Montana and adjacent Idaho (Barkley, 1978) .

B. PRESENT LEGAL OR OTHER FORMAL STATUS

1. BUREAU OF LAND MANAGEMENT: Senecio debilis is proposed as a sensitive species for the Dillon Resource Area. Documentation of it on many BLM lands in the Tendoy Mountains this past year provides basis for recommending that it be dropped from further consideration (Vanderhorst and Lesica, in progress) .

2. STATE: Senecio debilis is currently listed by the Montana Natural Heritage Program as "critically imperiled because of extreme rarity (5 or fewer occurrences, or very few remaining individuals) , or because of some factor of its biology making it especially vulnerable to extinction" (state rank = SI) . Documentation of it in the Tendoy Mountains this past year provides basis for recommending that it be changed to S3 (Vanderhorst and Lesica, in progress) .

occurrences were located for Senecio debilis including many new locations. The populations seems to be stable to increasing in numbers.

6. REPRODUCTIVE BIOLOGY: Senecio debilis reproduces by seeds resulting in a perennial plant.

H. LAND OWNERSHIP: Senecio debilis populations were located on both BLM and private lands.

II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS

A. THREATS TO KNOWN POPULATIONS: Populations of Senecio debilis appear to be stable at this time. Observations made in the Tendoy Mountains indicate that this species persists or increases under some level (s) of grazing (Vanderhorst and Lesica, in progress) .

B. FURTHER ASSESSMENT AND MANAGEMENT NEEDS: None identified.

C. SUMMARY: Senecio debilis is a Great Basin species that is found recurrently is alkaline meadows of Beaverhead County. Its number of populations and reported persistence (Vanderhorst and Lesica, in progress) under grazing provide basis for recommending that it be dropped from further consideration by BLM as a sensitive species.

GENUS: According to Hitchcock and Cronquist (1964) there are about a dozen species in western North America, chiefly in the desert region, often on alkaline soil (Greek thelys , female, and podion, little foot, referring to the (often) stipitate ovary.) There are seven genera of Thelypodium that occur in the northwestern portion of the United States.

5. SPECIES: Thelypodium saqittatum ssp saqittatum if found in moist, often alkaline meadows that usually dry by midsummer.

B. PRESENT LEGAL OR OTHER FORMAL STATUS

1. BUREAU OF LAND MANAGEMENT: Thelypodium ssp

saqittatum is proposed as a sensitive species for the Dillon Resource Area. Documentation of it on BLM lands in this study provides basis for recommending that its proposed status is appropriate.

2. STATE: Thelypodium ssp saqittatum is currently listed by the Montana Natural Heritage Program as "critically imperiled because of extreme rarity (5 or fewer occurrences, or very few remaining individuals) , or because of some factor of its biology making it especially vulnerable to extinction" (state rank = SI) . Documentation of it on BLM lands in this study and in the Tendoy Mountains (Vanderhorst and Lesica, in progress) provide basis for recommending that its MTHP rank be changed to S2 .

C. DESCRIPTION

1. GENERAL NONTECHNICAL DESCRIPTION: Thelypodium saqittatum ssp saqittatum is a biennial with distinct auriculate stem leaves. The mature fruits

36

are 0.5-1.2 mm wide and 0.7-1.3 mm long and somewhat flattened when fresh. The petals are 0.5-3 mm wide.

2. TECHNICAL DESCRIPTION: Thelypodium saqittatum ssp saaittatum have stem leaves that are mostly sessile and auricle, leaves are entire or merely sinuate to dentate, generally glabrous. The plants are biennial without creeping roots; sepals 5-8 mm; petals light to deep violet-purple, 10-16 mm; siliques straight, ascending, sessile or with stipe, scarcely 0.5 mm.

3. LOCAL FIELD CHARACTERS: Thelvpodium saqittatum ssp saqittatum occurs in moist alkaline meadows in large population in the early spring (late May-mid June) . The pink petals are short-lived, therefore the auriculate stem leaves in addition to the long, beaked fruits allows for easy identification.

D. GEOGRAPHICAL DISTRIBUTION

1. RANGE: Thelypodium saqittatum ssp saqittatum is found from desert plains to lower mountains in southeastern Wyoming to California, east to Montana and Wyoming.

2. CURRENT SITES: Thelypodium saqittatum ssp saqittatum was found in abundance during the spring of 1993. It was found in Red Rocks National Wildlife Refuge in the

bottomlands near the lakes. Also, there are element occurrences for BLM lands next to Lima Resevoir, Red Rock River, and Mud Lake. It is known in Montana only from the Centennial Valley and Tendoy Mountains of Beaverhead County.

E . HABITAT

1. ASSOCIATED VEGETATION: Thelypodium saqittatum ssp

saqittatum is found in moist alkaline bottomlands with Carex ssp. (sedges) , Juncus balticus (Baltic rush) and with the following grasses and forbs:

Deschampsia caespitosa (tufted hairgrass)

Dodecatheon pulchellum (few-flowered shooting star)

Festuca idahoensis (Idaho fescue)

Haplopappus uniflorus (one-flowered goldenweed)

Iris missouriensis (western blue flag)

Pentaphylloides floribunda (shrubby cinquefoil)

Phlox kelseyi (Kelsey's phlox)

Sarcobatus vermiculatus (black greasewood)

Valeriana edulis (edible valerian)

2. TOPOGRAPHY AND SOILS: Thelypodium saqittatum ssp

37

saqittatuin is found in bottomlands with open exposure. It is found in moist, alkaline soils.

F. POPULATION DEMOGRAPHY AND BIOLOGY

1. POPULATION SIZE AND CONDITION: Thelvpodium saaittatum ssp saqittatum population for the spring/summer of 1993 was abundant. It was the dominant species all along the lake and river bottomlands.

G. REPRODUCTIVE BIOLOGY: Thelypodium saqittatum ssp saqittatum is a biennial that reproduces by seed.

H. LAND OWNERSHIP: Thelypodium saqittatum ssp saqittatum was located on lands belonging to BLM, National Wildlife Refuge, and private.

II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS

A. THREATS TO KNOWN POPULATIONS: Populations of Thelypodium saqittatum ssp saqittatum appear to stable at this time. The only likely threat would be if grazing was to increase in the area where disturbance might produce detrimental effects.

B. FURTHER ASSESSMENT AND MANAGEMENT NEEDS: No altered management practices seem to be called for at this time. Should further surveys reveal a population decline because of disturbance, then monitoring of populations would be called for to assess whether or not livestock use posed a threat.

C. SUMMARY: Thelypodium saqittatum ssp saqittatum is recommended for addition to the proposed BLM list of sensitive species.

Astragalus arqophvllus Nutt. var. arqophvllus

Four new Centennial Valley populations were found of Astragalus arqophvllus var. arqophyllus. almost doubling the local number of populations. Included among these was one of the largest known populations at over 1000 plants, in T.14S R.5W Sec. 30 NW 1/4 on BLM lands. These results underscore the interpretation made in the Tendoy Mts. sensitive plant survey that this species is relatively widespread in southern Beaverhead Co. , MT (Vanderhorst and Lesica 1994) . Its habitat is often heavily used by cattle, but the species does not appear to show major decline under livestock grazing. For these reasons, it has been recommended that it be dropped from further consideration by the BLM and the Montana Natural Heritage Program.

It occupies wet, alkaline meadows associated with plants such as Juncus balticus, Poa nevadensis. Artemisia tripartita. Iris missouriensis and others. These are not shown on the Figure 2 map.

Astragalus lentiginosus (Rydb.) Peck var. salinus Howell) Barneby

Three new Centennial Valley populations were found of Astragalus lentiginosus var. salinus along the north side of the valley. These results underscore the interpretation made in the Tendoy Mts. sensitive plant survey that this species is relatively widespread in southern Beaverhead County, MT (Vanderhorst and Lesica 1994). Some of its populations in this other study are extremely large and had no apparent threats. For this reason, it has been recommended that it be dropped from further consideration by the BLM and the Montana Natural Heritage Program.

It occupies sagebrush habitat on sandy or clayey soils. Its Centennial Valley habitat is dominated by Artemisia tridentata or Agropyron spicatum with Festuca idahonis or Festuca scabrella. Other associated species include Lupinus sericeus, Bromis inermis. and Haplopappus acaulis. These are not shown on the Figure 2 map.

39 Astragalus terminalis Wats.

Two new Centennial Valley populations were found of Astragalus terminalis. However, both were found incidental to BLM surveywork and are located on Red Rock Lakes National Wildlife Refuge. Of the two previous records, one was near BLM land and may have extended onto BLM land, but this cannot be confirmed, and watch status is appropriate for the present.

The new records are from dry valley-bottom ecotonal settings, while the previous records are from subalpine slopes ca. 3000' higher than the valleybottom sites. This elevation amplitude is reflected in the species' habitat description (Hitchcock and Cronquist 1973) . One of the new sites is in an association of Artemisia tridentata / Festuca idahonis with nonnative grass encroachment. The other is at the edge of a stand of Populus tremuloides. While it occupies a range of elevations, it apparently restricted to limestone-derived substrate (Hitchcock and Cronquist 1973) . These are not shown on the Figure 2 map.

Draba globosa Payson (Draba apiculata Hitchc. var. apiculata)

Draba globosa was collected in the Centennial Mountains for the first time by Lynn Bacon on BLM land. The site is located at 9400' near the Continental Divide (Figure 2 map) . Detailed information was not collected on its population conditions or subalpine setting. This represents the fourth time it has been collected in Montana, All previous collections were in Madison County.

Stellaria iamesiana Torrey

Stellaria iamesiana was collected in Montana for the first time by Denise Culver in two BLM areas. It is mentioned in Dorn (1984) as "expected" in Montana, based on Dorn's familiarity with the species' habitat and distribution in Wyoming.

The two new records are from side valleys on the south side of the Centennial Valley as shown on the Figure 2 map. Both were found in moist, shaded lower slopes among Populus tremuloides with or without major Psuedotsuga menziesii cover.
