Vascular Plant and Sensitive Plant Species Inventory for the Highland Mountains, Deerlodge National Forest, Montana. Montana Natural Heritage Program. Helena, MT. 2 0 pp. plus appendix. INTRODUCTION The National Forest Management Act of 1976 mandates the protection of biological diversity on National Forest lands. One response to this mandate has been the development of sensitive species programs throughout the national forest system (Reel et al. 1989). Each national forest is reguired to protect the viability of sensitive species found within its bounds. Numerous plants that are listed as sensitive in the U.S. Forest Service Region One occur in the mountain ranges of southwest Montana (Lesica and Shelly 1991) . The Highland Mountains are a small alpine mountain range in southwest Montana. Much of this range is land administered by Deer Lodge National Forest. In spite of The Highland's proximity to Butte, there has been little botanical exploration of the area. Recently, Klaus Lackschewitz made collections in the area and discovered populations of Carex idahoa and Erigeron gracilis, but the size and extent of these populations was not reported. The Highland Mountains receive a great deal of use by recreationists as well as having mining, timber harvest and livestock grazing activity. In order to manage the Highland Mountains for the protection of biological diversity, the Forest Service must know which sensitive species are present, what habitats they occur in, and how common they are. The purpose of this study was to survey the Highland Mountains for sensitive plant species and report the size, location and habitat for these species. In addition, a complete list of all vascular plant species encountered during this study was prepared. This list will be useful to managers doing other studies in the area. STUDY AREA The Highland Mountains are a small alpine range in southwest Montana, just south of Butte. They lie between the Big Hole River and the Jefferson River on the south and east respectively, and they contain the headwaters of Silver Bow Creek and the Clark Fork River. The main divide ridge of the Highland Range is the Continental Divide. It runs between Red Mountain at 10,070 ft on the north, and Table Mountain at the south end, which is the highest peak at 10,200 ft. Slopes on the north, east and south sides are relatively steep, and streams and glaciers have formed canyons dropping to the main river valleys. On the west side of the divide there is a large plateau that is the headwaters of Moose Creek. Part of this plateau is referred to as Moose Town, while the northwest portion is called Burton Park. Low mountains (7,000-8,000 ft) surround Moose Town and Burton Park on the north, west and south sides. Low mountains on the west are called the Humbug Spires (Fig. 1) Figure 1. Map of Highland Mountain region and the areas surveyed for sensitive species. The core of the Highland Mountains is formed of Precambrian basement rock in the south and granite of the Boulder Batholith in the north (Alt and Hyndman 1986) . The Humbug Spires are low mountains formed of this granite. A band of calcareous Belt Series sedimentary rock, 5-10 miles wide runs from near the town of Divide west to just east of the Continental Divide (Alt and Hyndman 1986) . The crest of the Highland Mountains are argillite on the north near Red Mountain and quartzite and granite in the south around Table Mountain. Soils at 6,000-7,500 ft throughout most of the north portion of the area are derived from granite and are coarse-textured and well-drained. Soils in the south are derived from metamorphosed sedimentary rocks and are more silty or loamy in texture. Calcareous soils occur sporadically in the Moose Town area and just east of the Continental Divide in the Lime Kiln Hill and head of Fish Creek area (Fig. 1) . Soils near or above timberline are generally shallow and poorly developed. Small cirques along the main divide suggest that the core of the range was glaciated during Pleistocene times. Climate of the Highland Mountains is continental-montane with short, cool summers and long, cold winters. Butte, at 5,540 ft on the north side of the Highland Mountains, had mean July maximum and mean January minimum of 80.1 and 3.7°F respectively from 1950 to 1980 (NOAA 1982) . During this same period mean annual precipitation was 11.7 inches. Divide, at 5,406 ft on the west side of the study area, had mean July maximum and mean January minimum of 79.4 and 8 . 5°F respectively from 1950 to 1980 (NOAA 1982) . During this same period mean annual precipitation was 12.4 inches. Precipitation in the Highland Mountains is estimated to vary from 16-30 inches per year based on snow course records (USDA-SCS 1981) . June is the wettest month. Approximately half of the precipitation falls as snow during the winter. Vegetation of the Highland Mountains is predominantly coniferous forest dominated by Douglas fir (Pseudotsuga menziesii) and lodgepole pine (Pinus contorta) . Spruce (Picea enqelmannii) is common along streams and higher cool slopes. Whitebark pine (Pinus albicaulis) dominates subalpine and timberline forests. Limber pine (P^. f lexilis) is locally common on outcrops of calcareous parent material in the Moose Town and Fish Creek areas. Where granite is the parent material, coniferous forest generally dominates on all aspects (narrow mesas above Hells Canyon Creek are an exception) . On soils derived from metasediments, steppe dominated by sagebrush (Artemisia tridentata) , rabbit brush (Chrysothamnus spp.), shrubby cinquefoil (Potentilla fruticosa) and Idaho fescue (Festuca idahoensis) , occurs on warm slopes. Meadows dominated by tufted hairgrass (Deschampsia cespitosa) and sedges (Carex spp.) are common in Moose Town and Burton Park. Swamp and carr vegetation dominated by bog birch (Betula glandulosa) and willows (Salix spp.) are found along many drainages and in large areas of Moose Town. Groves of aspen (Populus tremuloides) occur sporadically in the Moose Town area. The Highland Mountains have been greatly impacted by human use. The area was the scene of a great deal of mining exploration. There are numerous old mines and associated roads in the Moose Town and Fish Creek areas. Concentrations of precious metals are presumably associated with the contact zone between the Belt sediments and the granite batholith. There is an active mining operation near the head of Fish Creek. Wherever steppe or meadows are the predominant vegetation, cattle grazing is a common use of the land. Douglas fir composing much of the forests are short and often deformed, but some areas of lodgepole pine forest have been clearcut. In addition, some trees have been harvested for firewood and lumber during the times when the area was a more active mining district. The Highland Mountains- Moffet Mountain-Moose Town area is a very productive wildlife area. I observed large numbers of elk, moose, deer, bighorn sheep and mountain goats. As a result, the area is heavily used by hunters during the fall. There is a good deal of recreational driving both on and off roads during the summer. The area is undoubtedly used by snowmobilers during the winter. METHODS For the purpose of my study, the Highland Mountains are defined as land administered by the U.S. Forest Service and private inholdings above 6,000 ft south of Pipestone Pass and Hwy 10, west of the Jefferson River Valley, and east and north of the Big Hole River Valley. I surveyed the Highland Mountains on June 25-July 6, 1992 and July 31-August 3, 1992. I concentrated my surveys in five areas (Fig. 1): (1) Moose Town/Burton Park - an abundance of wetlands and outcrops of calcareous parent material, (2) Fish Creek/Limekiln Mountain - numerous outcrops of calcareous parent material, (3) Red Mountain/Table Mountain - expansive alpine habitat, (4) Moffet Mountain - expanses of sagebrush steppe and high elevation grasslands, and (5) Hells Canyon Creek - coarse granitic soils and sagebrush steppe. I conducted my surveys by hiking transects through each area, inspecting typical habitat as well as unusual edaphic or topographic features. I recorded all vascular plant species observed and made representative collections of many species. I completed Montana Natural Heritage Program (MNHP) "Plant Species of Special Concern" forms for all species on the most recent MNHP list, and I completed MNHP-modif ied ECODATA forms for representative plant communities harboring species listed as sensitive in Region One of the U.S. Forest Service (Lesica and Shelly 1991) . Vascular plant nomenclature generally follows Hitchcock and Cronquist (1973). Nomenclature for willows follows Dorn (1984). Information on nomenclature for sensitive species and "species of special concern" can be found in Lesica and Shelly (1991) . Specimens are deposited in the herbarium of the University of Montana (MONTU) . In 1992 I received a separate contract from Deerlodge National Forest to conduct floristic surveys of the Table Mountain area. The results of that study (Lesica 1992) have been included in this report. RESULTS I recorded 526 species of vascular plants in 52 families from the Highland Mountains (Appendix A). Of these, seven are listed as sensitive in Region One of the U.S. Forest Service: Arabis fecunda, Carex idahoa, Juncus hallii, Orobanche corymbosa , Penstemon lemhiensis, Saxif raqa tempestiva and Thlaspi parvif lorum. Five additional species are listed as species of special concern by MNHP: Carex vallicola, Erigeron gracilis, Gentiana aguatica, Haplopappus macronema ssp. linearis and Ranunculus verecundus. Information on the occurrence of these species in the study area is given below. Additional information can be found in the MNHP element occurrence records in Appendix B. Copies of ECODATA forms for all sensitive species sites can be found in Appendix C. Element Name: Arabis fecunda Rollins Common Name: Sapphire rockcress Range: Endemic to the Sapphire, Pioneer and Highland mountain ranges of Beaverhead, Ravalli and Silver Bow counties, Montana. Element Rank: G2/S2 Federal Status: USFWS C2, USFS Region 1 Sensitive Local Occurrence: Two populations of A^. fecunda occur in the Moose Town area and two were found in the Fish Creek area (Fig. 2,3). Moose Town populations were estimated at 1,000-2,000 plants, while those in the Fish Creek area are larger, with 5,000-10,000 plants. All populations occur in mineral soil derived from metamorphosed calcareous sediments on south- or west-facing slopes. Associated plant communities are sparse Agropyron spicatum grasslands or very open limber pine woodland. Although apparently appropriate habitat occurs on Limekiln Hill, I was unable to locate the species in the area. Comments: All four populations occur in areas where there has been extensive mining exploration, and the southern Fish Creek population is within 1 mile of an active mine. Mining is probably the principal threat to A. fecunda in the study area. In addition, the northern Moose Town population is in close proximity to a major road and may be threatened by future road construction. Finally, the areas are subject to livestock grazing, but disturbance appears to be moderate at this time and is probably not detrimental to the species. These populations are on the eastern edge of the known range of the species. Element Name: Carex idahoa (Bailey) Common Name: Idaho sedge Range: Beaverhead, Madison, Powell and Silver Bow counties, Montana and southeast Idaho Element Rank: G2QS2 Federal Status: USFWS 3C, USFS Region 1 Sensitive Local Occurrence: I relocated the population in the Moose Town area and discovered another in the Fish Creek area (Fig. 2,3). Both populations occur in drier ecotonal areas of wet meadows along streams in areas influenced by calcareous parent material. Both populations contain fewer than 100 plants. The associated plant community is Potentilla f ruticosa/Deschampsia cespitosa. Comments: This plant is also referred to as Carex parryana Dewey ssp. idahoa (Bailey.) Murray. I searched for this plant throughout the study area, but located only these two populations. However, populations are usually small, and I may not have located all of them. Nonetheless, C^ idahoa does seem to be rare in the study area. Populations may be threatened by livestock grazing. In addition, the Moose Town population is immediately adjacent to a main road and could be threatened by road construction. Element Name: Juncus hallii Engelm. Common Name: Hall's rush Range: Southwest Montana and southern Idaho south to Colorado. In Montana this species is known from Madison, Meagher, Powell and Silver Bow counties. Element Rank: G4G5/S2 Federal Status: USFS Region 1 Sensitive Local Occurrence: I located one population of J^_ hallii in the Moose Town area (Fig. 2) . Unfortunately I was unsure of the identity of the plant when I collected it and did not take extensive information on the site. It occurs in moist soil on the drier margins of a wet meadow adjacent to an old logging road. Before the area was logged this meadow was in a matrix of moist spruce forest. My impression is that the population was small, probably less than 200 plants. Comments: At this site Jj. hallii occurs near a population of J_, tenuis, and the two species can be confused. The logging road through the area may have impacted this population when it was built, and timber harvest undoubtedly altered the hydrologic regime of the site. Element Name: Orobanche corymbosa (Rydb.) Ferris Common Name: Flat-topped broomrape Range: Southern British Columbia to southwest Montana, south to California, Nevada and Utah. In Montana the species is known from Beaverhead, Madison and Ravalli counties. Element Rank: G4/S2 Federal Status: USFS Region 1 Sensitive Local Occurrence: I located one population of CK. corymbosa in the Hells Canyon Creek area (Fig. 4) . Plants occurred in course- textured, granitic soil on gentle slopes of mesas on the northeast side of the canyon. The population consists of three subpopulations, all within 1 mile of each other. I estimated that at least 2,000 plants occur between these three subpopulations. Associated plant community is Artemisia tridentata/Festuca idahoensis. Comments: Although similar habitat exists both north and south of the three subpopulations, I was unable to locate any plants in these areas. Additional populations may occur on BLM or private land to the west and south of the study area. I am not aware of any threats to this population of O^ corymbosa . Element Name: Penstemon lemhiensis (Keck) Keck & Cronq. Common Name: Lemhi beardtongue Range: Endemic to Beaverhead, Ravalli and Silver Bow counties, Montana and Lemhi County Idaho Element Rank: G2/S2 Federal Status: USFWS C2, USFS Region 1 Sensitive 9 Local Occurrence: I discovered two populations of £_•_ lemhiensis in the Moose Town area (Fig. 2) . The eastern population consists of two subpopulations on opposite sides of a hill. Both populations occur in relatively sparse vegetation on soil derived from calcareous metasediments. Both populations were estimated to be 100-200 plants. Nearly all plants in the western population had been grazed down to near the base of the plant, probably by deer or elk but possibly by livestock. The associated plant community was Festuca idahoensis/Agropyron spicatum grassland. In addition to these two populations, I observed 3-5 plants on a roadcut ca. 1/2 mile south of Fish Creek (TIN R7W S33, NW1/4 of SW1/4). Plant were present only in disturbed soil immediately adjacent to the road so I did not map or document this occurrence. Comments: Penstemon lemhiensis occurs in areas that are subject to both mining activity and livestock grazing. Although P^ lemhiensis is probably enhanced by low or even moderate levels of disturbance, both mining development and grazing could be a threat to this species. These populations are on the eastern edge of the known range of the species. Element Name: Saxif raga tempestiva Elvander & Denton Common Name: Storm saxifrage Range: Endemic to Beaverhead, Deer Lodge, Granite, Ravalli and Silver Bow (?) counties, Montana Element Rank: G2/S2 Federal Status: USFS Region 1 Sensitive Local Occurrence: I located two subpopulations of S_s_ tempestiva on the west flank of Table Mountain (Fig. 5) . Both sites were snow cachement areas on relatively gentle terrain. The population was estimated to be fewer than 300 plants. Associated plant community was Geum rossii turf. Comments: Plants at the Table Mountain site appear intermediate between S^. tempestiva and S^. rhomboidea and may be a hybrid population (see Lesica 1992 for further discussion) . The area is subject to few direct human-caused disturbances. However, grazing by bighorn sheep in the area is intense, and this level of grazing may be having an impact on the vegetation. Bighorn sheep may be overusing this remote part of their range because of intense ORV use of lower, more accessible areas (Lesica 1992) . 11 Element Name: Thlaspi parvif lorum A. Nels. Common Name: Small-flowered pennycress Range: Endemic to southwest Montana, northwest Wyoming and central Idaho. In Montana this species is known from Beaverhead, Madison, Park and Silver Bow counties. Element Rank: G3/S2 Federal Status: USFS Region 1 Sensitive Local Occurrence: I located two populations of Tj. parvif lorum in moist grasslands and meadows on gentle slopes or alluvial terraces in the Moose Town area (Fig. 2) . The eastern population occurred in a somewhat drier site and was estimated at 100-1,000 plants. The western site was estimated at 1,000-10,000 plants. Associated plant communities are Potentilla f ruticosa/Festuca idahoensis and Potentilla fruticosa/Juncus balticus. Comments: I searched extensively for this species in the Moose Town area, but in spite of large areas of apparently potential habitat, I located only two populations. However, T\. parvif lorum is inconspicuous unless it is blooming, and it blooms very early and has completely disappeared by mid-summer. Thus, I may not have located all populations in the study area. Both Ti parvif lorum sites are subject to livestock grazing. The effects of grazing on the species are not known. Element Name: Carex vallicola Dewey Common Name: Valley sedge Range: Eastern Oregon to southwest Montana and western South Dakota, south to California, Utah and Mexico. In Montana the species is known from Beaverhead, Gallatin, Lewis & Clark, Madison, Park and Silver Bow counties. Element Rank: G5/S2 Federal Status: None Local Occurrence: I located one population of C\_ vallicola in mesic high-elevation grassland in the Limekiln Hill area (Fig. 3). The population was estimated to be 100-1,000 plants. The associated plant community is Festuca idahoensis /Agropyron caninum. Comments: This small population of C_j_ vallicola is in an area that has extensive mining exploration. The area is also subject 13 to livestock grazing. The plant is highly palatable to livestock and decreases with overgrazing (Hermann 1970) . Element Name: Erigeron gracilis Rydb. Common Name: Slender fleabane Range: Endemic to Southwest Montana, western Wyoming and east- central Idaho. In Montana the species is known from Beaverhead, Park, Silver Bow and Sweetgrass counties. Element Rank: G4/S2 Federal Status: None Local Occurrence: I located populations of E^ gracilis in the Moffet Mountain, Moose Town and Fish Creek/Limekiln Hill areas (Figs. 2,3,6). The plant appeared to be widespread throughout much of the Highland Mountains in silty to loamy soils of mesic to moist steppe and grasslands. Populations were all estimated to be larger than 1,000 plants. Associated plant communities are Artemisia tridentata/Festuca idahoensis (Geranium phase) and Potentilla f ruticosa/Festuca idahoensis. Comments: Erigeron gracilis was common enough in the study area that I did not purposely look for it but mapped only occurrences that I observed while surveying for other species. It is probably not threatened in the study area. Element Name: Gentiana aquatica L. Common Name: Wet meadow gentian Range: Southern Alberta and Saskatchewan south to Colorado; also in Asia. In Montana the species is known from Beaverhead, Madison and Silver Bow counties. Element Rank: G4/S2 Federal Status: USFWS 3C (under synonym of (L. fremontii) Local Occurrence: I located one population of G^ aquatica in the Fish Creek area, in the same meadow as Carex idahoa (Fig. 3) . The species occurs on shrub-dominated hummocks in an alkaline meadow along a small stream. Associated plant community was Potentilla f ruticosa/Deschampsia cespitosa. I estimated the population to be greater than 1,000 plants. Comments: This meadow is subject to livestock grazing. Trampling of this wet site resulting from overuse by livestock could degrade the site and negatively impact the G^. aquatica population. Element Name: Haplopappus macronema Gray ssp. linearis (Rydb.) Hall Common Name: Discoid goldenweed Range: The subspecies is endemic to northwest Wyoming and southwest Montana. In Montana it is known from Beaverhead, Madison, Meagher and Silver Bow counties. Element Rank: G4T7/S2 Federal Status: None Local Occurrence: I located two populations of Hj. macronema linearis in moist steppe in the Moose Town/Burton Park area (Fig. 7). The Burton Park population was estimated to be fewer than 300 plants, while the Moose Town population was estimated to be 500-1,000 plants. Associated plant communities were Artemisia tridentata/Festuca idahoensis and Potentilla f ruticosa/Festuca idahoensis. Comments: Although there is an abundance of apparently appropriate habitat in the study area, I located only two populations of H^. macronema linearis. Many of the plants at the Burton Park site had been broken due to livestock trampling. However, the plant seems to respond positively to disturbance at the Moose Town site, being most common near fences and along roads. Element Name: Ranunculus verecundus Robins. Common Name: Modest buttercup Range: Alaska south to Oregon, Idaho and Wyoming. In Montana this species is known from Glacier National Park and the Highland and Anaconda ranges in Beaverhead, Deer Lodge and Madison counties. Element Rank: G5/S1 Federal Status: None Local Occurrence: I located one population of R^ verecundus in wet tundra on the west shoulder of Table Mountain (Lesica 1992, Fig. 5) . Associated plant community was Deschampsia cespitosa/Caltha leptosepala. Population size was estimated to be 200-500 plants. Comments: Typical R^_ verecundus has deciduous sepals and persistent petals. Plants from the Table Mountain site have persistent sepals and lack petals (Lesica 1992). The area is subject to few direct human-caused disturbances. However, grazing by bighorn sheep in the area is intense, and this level of grazing may be having an impact on the vegetation. Bighorn sheep may be overusing this remote part of their range because of intense ORV use of lower, more accessible areas (Lesica 1992) . DISCUSSION The Moose Town area has a great diversity of parent materials and soils. Coarse-textured sandy soils derived from granite of the Boulder Batholith occur on the northern periphery. The majority of the upland areas have silty or loamy soils derived from metasediments, including outcroppings of calcareous parent material. These soils support Douglas-fir and lodgepole pine forests, limber pine woodland, sagebrush and cinquefoil steppe, and grasslands. The area also has a complex hydrologic geology and supports a vast array of wetland communities including aspen groves, wet spruce forests, willow swamps, fens, marshes and wet meadows. The diversity of plant communities and the extent of the wetlands is exceptional. The area is also important habitat for many species of wildlife including elk, moose and bighorn sheep. Fives species of vascular plants listed as sensitive in U.S. Forest Service Region One occur in the Moose Town area (Fig. 2) : Arabis fecunda, Carex idahoa, Juncus hallii , Penstemon lemhiensis and Thlaspi parvif lorum. Both A_j_ fecunda and P_j. lemhiensis are candidates for listing as threatened or endangered species by the U.S. Fish and Wildlife Service, and all but J^_ hallii are endemic to small areas of southwest Montana and adjacent Idaho and Wyoming (Lesica and Shelly 1991) . In addition, Erigeron gracilis and Haplopappus macronema ssp. linearis, two regional endemics that are MNHP species of special concern, are also found in this area (Fig. 2,7). The habitat diversity and number of rare plant species make the Moose Town area the most outstanding biological area in the Highland Mountains. Unfortunately, the area has suffered a great deal of human-caused disturbance. It was the site of numerous mines and prospects, and apparently a small community existed there in the past. There are unreclaimed tailings heaps and mine shafts as well as water diversion ditches and old cabins. Probably more damaging are the numerous roads and 4-wheel drive trails throughout much of the area. These roads and trails continue to be used for recreation by residents of Butte and the surrounding area. The area is grazed by livestock during July and August, and some of the wetland and upland communities have been degraded as a result. Finally, forests on the north and 18 west sides of the Moose Town area have been clearcut. All of these disturbances have had and, in some cases, continue to have a negative impact on wildlife, populations of sensitive plants and the integrity of native communities. Biological values in the Moose Town area could be protected by diminishing and mitigating human-caused disturbances: (1) limiting motorized vehicle traffic to main roads, (2) managing livestock to protect fragile wetland and riparian areas and prevent overgrazing of adjacent uplands, (3) reclamation of mine sites, and (4) limiting timber harvest to protect watershed values and wildlife. Approximately 1,800 acres of the Moose Town area is in private ownership; the rest is public land managed by the U.S. Forest Service and the Bureau of Land Management. A cooperative management plan for the area that addresses these issues is essential for maintaining the ecological integrity and biological diversity of the area. The Fish Creek/Limekiln Hill area harbors populations of Arabis fecunda and Carex idahoa, both of which are on the U.S. Forest Service Region One sensitive species list. In addition, there are populations of three MNHP species of special concern in the area (Fig. 3) . This area is similar to the Moose Town area in its history of mining and livestock grazing, and there is an active mine along Fish Creek at this time. The topography is steeper, so there are fewer opportunities for off-road vehicle abuse. Although I do not believe that this area has the biological significance of the Moose Town area, developments and livestock management should be regulated to protect populations of rare and sensitive species. 19 LITERATURE CITED Alt, D. and D.
