ABSTRACT Under congressional mandate, each unit of the National Park Service is required to develop comprehensive species lists that capture at least 90% of their total flora and fauna. Bighorn Canyon National Recreation Area was surveyed extensively from 1976-1984, resulting in the documentation of over 650 vascular plant taxa for the park. Rare plant surveys in 1998-99, however, resulted in the discovery of 60 additional species, calling into question whether Bighorn Canyon NRA had achieved the 90% threshold. In 2001 we were contracted to revise the existing checklist of the park’s flora and conduct field surveys in under-sampled habitats to identify potentially missing species. After extensive review of the existing literature and herbarium collections at Bighorn Canyon and the Rocky Mountain Herbarium, we identified 81 species that had been falsely reported for the park and 45 additional taxa that could not be verified. Our herbarium search and fieldwork also identified over 120 additional species that had not previously been identified for Bighorn Canyon, including 22 additional weed species. Our revised checklist now contains 739 vascular plant taxa, all of which have been verified with voucher specimens or reliable observation data. We also compiled a list of 148 potential species that could occur in the study area due to the presence of suitable habitat. If we add the 44 potential species with the highest probability of occurring in the park, the current checklist would still represent over 94% of the total flora. Some relatively inaccessible areas of the National Recreation Area and cryptic or taxonomically difficult species groups remain undersampled, but overall, the known flora of Bighorn Canyon is probably at or near the 90% target level. ACKNOWLEDGMENTS We thank National Park Service staff for their interest, help and support. Lane Cameron (Biological Inventory Coordinator for the Greater Yellowstone Network) provided coordination throughout the project. Field plans were coordinated with Rick Lasko (Bighorn Canyon National Recreation Area). The planning contributions of Martina Keil, and the benefit of information on BICA herbarium additions compiled by Suzanne Morstad in addition to her observations were indispensible. Boat transporation was coordinated through Chris Ryan. We appreciate the opportunities to discuss this project with Darrell Cook, Theo Hugs, and other NPS staff. The herbarium and data resources of the University of Wyoming - Rocky Mountain Herbarium (RM) were vital and are acknowledged with deepest gratitude. B. E. Nelson, manager of the RM, shared information from his collections at Bighorn Canyon in 1979-1980. Dr. Dennis Knight of the University of Wyoming provided a box of old data forms, photos, and original notes from the floristic and ecological studies of Robert Lichvar, Ellen Collins, and Yoshiko Akashi at Bighorn Canyon in the early 1980s. We thank Scott Laursen and Melanie Arnett for help in compiling herbarium information at the RM, and Martin Miller (Montana Natural Heritage Program) for help processing the 2001 rare plant information in Montana. Stuart Markow helped greatly in specimen review. The report benefited by the reviews of Robert Dorn, B. E. Nelson, Lane Cameron and Suzanne Morstad. This project was conducted in collaboration with the Montana Natural Heritage Program. It was supported by the Inventory and Monitoring Initiative of the National Park Service - Greater Yellowstone Network.

INTRODUCTION The National Park Service established Bighorn Canyon National Recreation Area* in 1966 to promote recreational opportunities on Yellowtail Reservoir and to protect historical sites, such as the Mason-Lovell Ranch and Bad Pass Trail. Due to its location at the confluence of the Great Plains, Central Rocky Mountains, and Wyoming Basins ecoregions, Bighorn Canyon harbors an unusually rich diversity of vegetation types and over two dozen locally endemic or rare plant species (Knight et al. 1987; Heidel and Fertig 2000). From a conservation perspective, Bighorn Canyon National Recreation Area is significant because it is one of the few areas in the northern Bighorn Basin and adjacent foothills of the Bighorn/Pryor Mountains that is permanently protected and managed with an emphasis on maintaining biological processes (Merrill et al. 1996). An important mission of the National Park Service is to conserve the natural, recreational and cultural resources of each park unit for current and future generations. In spite of this emphasis, many parks have lacked comprehensive inventories of their flora and fauna or monitoring programs to assess impacts of management actions on target species. In 1998, Congress directed the Park Service to develop a program to inventory and monitor the biological resources of the entire park system in order provide better informed management decisions. Since 1999, the Park Service has been conducting regional expert workshops to determine the state of existing knowledge on the biota of each park and to identify data gaps and research needs. The ultimate goal of this effort is to attain a 90% complete species checklist and develop monitoring programs for each park unit (National Park Service 2000). An initial floristic survey of Bighorn Canyon by Lichvar et al. (1985) documented 656 vascular plant taxa for the National Recreation Area. In conjunction with a rare plant inventory in 1998-1999, Heidel and Fertig (2000) documented 60 additional plant taxa for the NRA, calling into question whether the existing checklist represented at least 90% of the actual flora. In April 2001, the Greater Yellowstone Network of the National Park Service contracted with the University of Wyoming’s Natural Diversity Database (WYNDD) to revise the existing checklist and conduct new field surveys to assess whether the 90% representation goal had been achieved. In addition, WYNDD was charged with documenting new localities of noxious weeds and rare plants. The results of this study are summarized on the following pages. This report includes an annotated checklist of the known flora of Bighorn Canyon, lists of falsely reported and unconfirmed species, and a list of plants that potentially occur in the area. STUDY AREA Bighorn Canyon National Recreation Area parallels Yellowtail Reservoir (Bighorn Lake) for 71 miles from the vicinity of Kane, Wyoming to Fort Smith, Montana (Figure 1). It encompasses 22,499 ha (55,595 acres) and ranges in elevation from 1100-2450 meters (3600-8040 ft). It also includes the Yellowtail Reservoir that has completely inundated the original Bighorn Canyon. * The NPS code that is used to denote Bighorn Canyon National Recreation Area is “BICA”. This code is used in the report to refer to both the study area and the NPS herbarium facility in particular.

Downcutting by the Bighorn River and regional faulting and erosion have exposed thick Paleozoic limestone and dolomite cliffs, soft red Cretaceous sandstones, and Quaternary alluvium and pediments (Love and Christensen 1985). Knight et al. (1987) documented 21 main vegetation types in the study area, ranging from lakeshore marshes and floodplain woodlands to prairie grasslands and coniferous forests at higher elevations. The most common vegetation type by far, however, is Utah juniper/Curlleaf mountain mahogany, which covers over 40% of the NRA. Based on vegetation, geology, and landforms, the Bighorn Canyn National Recreation Area can be subdivided into three distinct biogeographic units that roughly correspond with the boundaries of the three counties that intersect the park. The southernmost segment lies in Big Horn County, Wyoming. Much of this area consists of rocky outcrops of red sandstone, and desert shale barrens dominated by Utah juniper, curlleaf mountain-mahogany, greasewood, shadscale, Gardner’s saltbush, and other desert species with affinities to the flora of the Great Basin. This section is the driest portion of the study area and averages just 6.7 inches of annual precipitation (based on NOAA records from Lovell, WY). The southern unit also contains riparian woodlands, extensive marshes along the floodplain of Yellowtail Reservoir and uplands that are in the Yellowtail Wildlife Habitat Management Area, co-managed with the Wyoming Game and Fish Department. The middle segment of the study area is mainly in Carbon County, Montana. It has the highest elevation of the three segments because it includes the face of the Pryor Mountains escarpment, but is primarily a dry foothills landscape, dissected by steep limestone and dolomite canyons. The vegetation consists of arid foothills grasslands, Utah juniper and curlleaf mountain mahogany shrublands, and limited coniferous forests of Douglas-fir, limber pine, and Engelmann spruce and subalpine fir (Knight et al. 1987). This area also contains numerous cold water seeps that provide habitat for a number of rare wetland plants, including Sullivantia hapemanii (Heidel and Fertig 2000). Due to its diversity of habitats and topography, the middle segment has the highest species richness of any of the three segments comprising the study area. Lichvar et al. (1985) reported a number of subalpine and alpine taxa from this area, but most of these species were actually found on one section of state land just west of the present National Recreation Area boundaries. The southern and middle segments of the NRA contain most of its local and regional endemic species, such as Eriogonum brevicaule var. canum, Erigeron allocotus, and Rorippa calycina. The Montana portion also contains a high percentage of rare desert plants at the northern margins of their range that are found nowhere else in that state (Dorn 1978; Heidel and Fertig 2000). The northernmost segment of the study area lies within Big Horn County, Montana. It is the wettest segment of the study area. The area around Fort Smith has an annual precipitation averaging 18.9 inches. It is a separate unit connected to the other segments by the Yellowtail Reservoir. The land area of this northernmost unit is over 10 times smaller than the other two segments. However, it includes well-developed mesic valley bottom vegetation and perennial coldwater streams within 30 ft. of the reservoir highwater level under NPS administration, unlike the other segments. In addition, the north unit contains Great Plains vegetation, foothills woodlands, and a short reach of the free-flowing Big Horn River. The Three Mile Fishing Access area located 3 miles north of the northeastern end of the National Recreation Area was not included in this study.

METHODS Lichvar et al. (1985) assembled a vascular plant species checklist for Bighorn Canyon National Recreation Area based on collections made during floristic and vegetation surveys in 1983-84. Heidel and Fertig (2000) amended this list to include species records from their rare plant survey work in 1998-99, as well as additional species reported by Knight et al. (1987), and additions among the collections of the Bighorn Canyon National Recreation Area Herbarium (BICA). Prior to survey work in 2001, we reevaluated every entry in our preliminary checklist to ensure that all species were corroborated by a valid voucher specimen or observation. An initial sweep of the Rocky Mountain Herbarium (RM) revealed a number of specimens that were either misidentified or were collected outside the boundaries of Bighorn Canyon National Recreation Area. In May 2001, Fertig reexamined the entire BICA collection to confirm the identity of all voucher specimens, verify their presence within the study area, and annotate the preliminary checklist with county-level distribution data. From this new information we developed a working checklist that highlighted those species still in need of confirmation in the field or from the collections at RM. Field surveys in 2001 focused on six undersampled vegetation types that we identified during our rare plant inventory in 1998-99: riparian corridors of coldwater streams, cushion plant communities, marsh and forest riparian habitat, cliffs, montane grassland, and seeps (Heidel and Fertig 2000). We also inventoried those sites that had more difficult access and areas that required repeat visits to capture the phenological array of species. In particular, we emphasized early and late-flowering graminoids, exotics, and composites that appeared to be undersampled in previous studies. Survey locations were scattered across the three segments of the study area to ensure geographic breadth of inventory, in keeping with National Park Service inventory guidelines (USDI National Park Service 2000). We did not include species planted by the National Park Service or at the landscaped headquarters in Lovell, Wyoming. We did include species that persisted from plantings that pre-date BICA establishment in 1966. Our herbarium work and fieldwork required four visits to Bighorn Canyon between 29 May and 11 August 2001. In the field we made collections of species that were either additions to the study area flora or which had not previously been vouchered. Collecting was done only if plant populations were sufficiently large. When necessary, we substituted detailed observation data for physical specimens. In the case of rare species or noxious weeds, we documented new location and habitat data to augment existing records within the study area. For all species we recorded county-of-distribution information within the National Recreation Area. Voucher specimens were taken to the Rocky Mountain Herbarium (RM) for identification and deposited there. Duplicate sheets were prepared for deposit at BICA. At the conclusion of the field season, we created a revised checklist incorporating the additional species collected or observed in 2001. We also rechecked the collections of the RM for all remaining species on the initial checklist that lacked vouchers at BICA or were not relocated in the field. Using the RM’s digital specimen database, we were able to locate several dozen historical records from the park, including 49 collections made by B. Ernie Nelson in 1979-80 that were not included by Lichvar et al. (1985). The entire checklist was revised to follow the standard nomenclature of Kartesz and Meacham (1999) as used in NPSpecies database for scientific and common names. Synonyms were provided if these names differed from those used in the current statewide floras of Montana and Wyoming (Dorn 1984, 2001).

Our final checklist contains all vascular plant taxa known to occur in Bighorn Canyon National Recreation Area based on verified voucher specimens or observations (Appendix A). This list has been annotated to include global heritage rank (NatureServe 2001, http://natureserve.abi.org/), native or exotic status (Fertig 1999a), distribution within the National Recreation Area by county, a representative voucher collection (with collector and repository), date of first documentation in the study area, and other pertinent comments. Appendix B and C contain lists of species that were previously reported for the park but have either been rejected or cannot be confirmed at present. To test whether the flora of Bighorn Canyon has been adequately sampled, we developed an additional list of species that may potentially occur within the area, but which have not yet been documented (Appendix D). This list was created by comparing our confirmed species list with the Rocky Mountain Herbarium’s digital “Atlas of the Vascular Plants of Wyoming” (www.esb.utexas.edu/chumley/wyomap/atlas.htm) and checklists of the flora of the Pryor Mountains, Bighorn Range, and Bighorn Basin (Lesica and Achuff 1992, Fertig 1999b). The probability of occurrence for each species was given a rank of high, medium, or low depending on its global abundance and the presence of suitable habitat in the study area. Additional comments are provided on where these species are most likely to be found within Bighorn Canyon. RESULTS Summary of Plant Inventory Work at Bighorn Canyon National Recreation Area Prior to 1976, botanical studies in the Bighorn Canyon area were limited to sporadic collections or baseline ecological surveys of dominant community types (Table 1). The earliest known collection from the area is a specimen of Sarcobatus vermiculatus made by R.C. Snelling in 1924 (Rocky Mountain Herbarium records). During the next 50 years, only three additional species were collected and deposited at the RM from the Wyoming portion of the NRA (early records from Montana are poorly known, although W.E. Booth made a small number of collections in the vicinity of Bighorn Canyon in the 1950s and 1960s, deposited at Montana State University.) All previous botany and vegetation studies cited by Lichvar et al. (1985) and Knight et al. (1987) are from outside the BICA study area. They did not mention and we were not able to determine the source of two unpublished plant checklists for Bighorn Canyon in 1968 (110 species) and 1975 (225 species) (Anonymous 1968, 1975). The source and authenticity of these floristic records has not been confirmed. Robert Dorn documented 24 additional plant taxa for the NRA in 1976-77 while doing general collecting in Carbon County, Montana (Dorn 1978). M.L. Roberts, a University of Wyoming graduate student, added one species in 1976. Collections were also made by B. E. Nelson, University of Wyoming (RM) in 1979-80 as part of a multi-year floristic survey of the Bighorn Range and surrounding basins (Nelson and Hartman 1984). Nelson documented 49 additional species for the NRA at the mouth of John Blue Canyon and along Yellowtail Reservoir in Big Horn County, Wyoming. In 1981-82, Park Service employees Terry Peters, Kathy Jobe, William Messerschmidt, and Arlene Wolf made over 100 collections from Horseshoe Bend, Trail Creek, and Barrys Landing in Wyoming and Montana and added 56 additional species to the park’s flora (BICA records).

The first truly systematic inventory of the flora of Bighorn Canyon National Recreation Area was conducted in 1983 by Robert Lichvar and Ellen Collins of the Wyoming Natural Heritage Program in collaboration with Dr. Dennis Knight of the University of Wyoming. Lichvar and Collins made over 600 collections (deposited at BICA, RM, and the New York Botanical Garden) and reported nearly 500 additional species for study area. In 1984, Knight and his student collaborators (George Jones, Dale Dittola, Richard Myers, and Yoshiko Akashi) added several hundred additional vouchers and at least 47 additional taxa (BICA and RM records) in the course of documenting the study area vegetation. Based on their own collections and the records of Dorn (1978), Lichvar et al. (1984, 1985) reported 656 vascular plant taxa for Bighorn Canyon. This list did not include many of the earlier records of B. E. Nelson deposited at the RM or specimens deposited at BICA by National Park Service staff. The Lichvar et al. (1985) checklist also contained at least 60 taxa that were misidentified or collected outside of Bighorn Canyon National Recreation Area and 45 species that cannot be confirmed today with vouchers. Based on our reassessment, the 1983 and 1984 collections of Lichvar, Collins, Knight, Jones, and associates added 431 additional species to the flora. Only three species were added to the flora between 1985 and 1998. Bonnie Heidel, Walter Fertig, and Laura Welp of the Montana and Wyoming natural heritage programs documented 60 additional taxa at Bighorn Canyon National Recreation Area during rare plant surveys in 1998-99. Heidel and Feritg (2000) compiled a revised checklist containing all additional records collected since 1985 and reports from Knight et al. (1987), and the collections at BICA that were omitted by Lichvar et al. (1985). This list identified 774 vascular plant taxa for the NRA. Flora of Bighorn Canyon National Recreation Area Based on our field surveys in 2001 and review of existing voucher specimens at RM and BICA, the flora of Bighorn Canyon National Recreation Area currently consists of 739 vascular plant taxa (Table 2, Appendix A). We observed or collected 76 additional species for the area in 2001 and relocated 33 taxa previously reported by Lichvar et al. (1985) that had been misidentified or lacked corroborating voucher specimens from within Bighorn Canyon. Suzanne Morstad (NPS) discovered 2 additional species in 2001 and we located 8 additional species records from previously overlooked specimens at RM and BICA. Our surveys and herbarium work added 407 county distribution records within the NRA, increasing the size of each subunit’s flora by 28-36% (Table 3, Appendix A). Our revised checklist does not include 81 species from Heidel and Fertig (2000) or Lichvar et al. (1985) that have been shown to be falsely reported (Appendix B). Of these taxa, 51 were misidentified and 30 were collected just outside of Bighorn Canyon National Recreation Area. An additional 45 species reported from previous checklists still cannot be confirmed by authenticated voucher specimens or observations (Appendix C). According to Robert Dorn (personal communication), some of these “missing” specimens may have been deposited at the New York Botanical Garden, rather than RM or BICA (we have been unable to confirm this). We believe that at least 34 of the 81 rejected species and 37 of the 45 unconfirmed species still have some potential to be found in the study area based on their occurrence in similar habitats in the vicinity (Appendix D).

Big Horn, WY 342 99 + 28.9% Carbon, MT 493 138 + 28.0% Big Horn, MT 463 170 + 36.7% Noxious Weed Documentation We documented 22 additional species of non-native plants on Bighorn Canyon National Recreation Area in 2001, bringing the total number of exotic plants in the park to 105 (an increase of 21.0%). Non-natives now account for 14.2% of the total flora. By comparison, exotic plants represent only 12.6% of the flora of Wyoming (Fertig 1999a). Twelve species considered noxious weeds in Montana or Wyoming occur within the study area and one additional species has been reported, but could not be confirmed in 2001 (Table 4). Although weeds were not the primary focus of our 2001 fieldwork, we documented several new populations of salt-cedar (Tamarix chinensis) and Russian knapweed (Acroptilon [Centaurea] repens) that were not previously recorded in Bighorn Canyon National Recreation Area noxious weed GIS database. Salt-cedar was located along several side drainages of Bighorn Canyon but was most abundant at the southern end of the study area in the Yellowtail Wildlife Habitat Management Area. Low-water conditions in 2001 exposed extensive areas of mudflats that are being rapidly colonized by Salt-cedar seedlings. Discrete patches of Russian knapweed were located along the Ok-a-Beh road and Frozen Leg picnic site, widely-distributed at the highwater margins, and colonizing on the newly-exposed mudflats at the southern end of Yellowtail Reservoir. Additional Rare Plant Records in Bighorn Canyon National Recreation Area No additional rare plant species were discovered during floristic surveys in 2001, although we did identify several new locations for Sweetwater milkvetch (Astragalus aretioides), Lesica's bladderpod (Lesquerella lesicii), persistant-sepal yellowcress (Rorippa calycina) and Hapeman's sullivantia (Sullivantia hapemanii var. hapemanii). Rorippa calycina was documented at several
1 Some differences in the number of families and genera between 1985 and 2001 reflect changes in taxonomic concepts rather than the documentation of new species. Following Dorn (2001), the number of families recognized in 2001 would increase to 91.

new locations on newly exposed mudflats at the south end of Yellowtail Reservoir, demonstrating the capacity of this species to rapidly colonize new habitat given a local seedbank. One new population of Sullivantia hapemannii was discovered and an extensive habitat complex just upstream and downstream of Yellowtail Dam was surveyed. Printouts and electronic files of all rare plant records documented in the 1998-99 and 2001 studies will be submitted separately. Table 4.

DISCUSSION Based on our reassessment of all previous reports and review of herbarium specimens (RM and BICA), the flora of Bighorn Canyon National Recreation Area consisted of 628 confirmed taxa as of 1999 (Table 5). Fieldwork in 2001 resulted in the discovery or relocation of 111 additional species for the park, increasing the total flora to 739 species. The net increase of 15.0% confirms our suspicions that the documented flora of Bighorn Canyon National Recreation Area was below the 90% target goal of the National Park Service. The large increase in number of additional species relative to time and collection effort (Figure 2) suggests that additional taxa remain to be found at the study area. Our potential species list (Appendix D) includes 148 taxa from adjacent areas of Montana and Wyoming that could occur within the study area. Forty-four of the potential species are considered “highly probable” because of their region-wide abundance and preference for common habitat types present in the area. If these 44 taxa were added to the Bighorn Canyon checklist, the current species count of 739 taxa would still represent 94.4% of the total flora, well over the 90% threshold. This percentage drops to 87.0% if an additional 66 species of moderate probability are included in the checklist and 83.3% if 38 low probability species are recognized. Since many of these low to moderate probability taxa are unlikely to be documented, the current checklist of Bighorn Canyon NRA is probably very close to the Park Service’s goal of 90% completeness.

Some additional geographic areas, habitats, and taxonomic groups may be targeted for future survey to ensure that Bighorn Canyon National Recreation Area meets the park service goal of a 90% complete flora. The high-elevation western boundary of the National Recreation Area on the midslopes of East Pryor Mountain was partially surveyed for rare species in 1998-99 but has not been revisited for more common plants. Some species that extend downslope from higher elevation subalpine habitat types may have been missed in our survey. Several sites along Yellowtail Reservoir are inaccessible by land and may still be undercollected. The sand dune deposits below the mouth of Big Bull Elk Creek were surveyed for rare species in 1998-99 but have not been revisited for more common plants. Disturbed habitats and wetlands yielded high numbers of additional taxa in 2001 and may still harbor undocumented species, especially in taxonomically difficult families (such as Asteraceae, Poaceae, and Cyperaceae). A number of cryptic plants, as well as species with early or very late phenologies, may still be undersampled. Some species that we consider “undocumented” may actually have valid vouchers in the collections of the New York Botanical Garden, but to confirm this will require either a visit to the facility or a specimen loan. Finally, we were not able to work at the Montana State University Herbarium, where there may be additional specimens from the study area collected by W.E. Booth. The highest priorities would be to review the list of already confirmed species and those with a high probability of occurring in the Bighorn Canyon National Recreation Area.

Appendix B.
Rejected Taxa
The following vascular plant species have been reported from Bighorn Canyon National Recreation Area based on collections at the RM and BICA herbaria and reports from Lichvar et al.
