The Intermountain Region of the Forest Service (USFS Region 4) implemented a· · sensitive species policy to address the management needs of rare vascular plant species that might qualify for listing under the Endangered Species Act (Joslin 1994) .under a . 1982 planning rule. A total of 11 species were designated sensitive by USFS Region 4 . and one species designated by Bridger Teton National Forest (BTNF) as occmTing on BTNF. Field studies conducted by botanists with the Forest Service, Rocky Mountain Herbarium, Wyoming Natural Diversity Database (WYNNDD) and private investigators have subsequently· shown that some of the currently listed species may no longer wanant sensitive status, while some new species should be considered. - ·
A systematic review of Wyoming species of concern was prepared for the Intermountain Region of the Fo1:est Service (Fe1iig 2000), following the list of plant species recognized as Wyoming species of concern in Fertig and Beauvais (1999). That review was not incorporated as there were no sensitive list updates. Subsequentrevisions to the planning rule were put in place in 2005, charging Forests to designate species Species of Concern (SOC) and making provisions for Forests to also designate Species of Inte1:est (SOI). The Bridger-Teton National Forest resource management plan updating process began in 2006 under the new plam1ing rule.
The definition for SOC is those species that could trend toward listing under the _Endangered Species Act, corresponding with species ranked G 1-G3 by N atureServe. The definition for SOI is those species that are rare within the state, ranked S l-S3. In order to consider which species are rare throughout their distribution, or rare in the state of Wyoming, the BTNF requested the services of WYNDD to provide compiled lists of all globally rare and state rare species documented on the BTNF. This provides an opportunity to convey the most current botanical infonriation and pertinent resources, and to evaluate alternate processes and their outcomes. This process also provides an opportunity to consider the collective species found on BTNF that are scarce and of potential conservation concern throughout their range or throughout Wyoming.
METHODS
Three processes were. pursued to assemble and compile lists of species documented from the Bridger-Teton National Forest (BTNF) that are rare throughout their range, or throughout Wyoming. The resulting lists are presented in this report for· use in the development of the BTNF Species of Concern (SOC) and Species ofii1terest (SOI) on the Forest.
First, a pre-existing NatureServe list was reviewed. Ir represented all species that · are in the WYNDD database fi-0111: the three counties that encompass BTNF (Lincoln, Sublette and Teton counties). This includes species that are no longer tracked as species' of concern in Wyoming but are retained in the Yv7YNDD database as reference. The
2 NatureServe list was annotated to differentiate which species are on the Forest or outside of the Forest, and whether or not they are tracked as species of concern in Wyoming.
Second, a WYNDD export was prepared. Unlike the NatureServe list, it represented only Wyoming species of concern or potential concern (Heidel 2007) and only those that are on the BTNF. Thus, the WYNDD expo1i list is a subset of the NatureServe export list.
Third, a working compilation of the vascular plant flora of the BTNF was prepared from three floristic inventories on BTNF that documented the flora in the Gros Ventre Range.(Hartman and Nelson 1994), the Salt and Wyoming Ranges (Haiiman 1995), and the west slope of the Wind River Range (Fertig 1992). Results from tlwse studies were recorded on a master spreadsheet of the state flora (Fe1iig 2002) based on the most cmTent printed flora (following the taxonomic and distribution data in Dorn 2001); to produce an annotated checklist of the lrnown flora of BTNF. A total of 1386 species are lmown from the BTNF.
The master list of species of BTNF were s01ied by Global rank (Grank) and by State rank (Srank) to produce draft lists of the Species of Concern (SOC) having high Grank priorities (Gl-G3G4), or other Species oflnterest (SOI) having high Srank priorities (S 1-S2). A total of 68 SOC $pecies and 270 SOI species were identified. Information was added for BTNF to weigh in screening the candidates, including primary elevation zone (basin, montane, or·alpine), vegetation (structural categories filled in for all montane species and for most basin species), .cross-reference to Fertig (2000), and cross-reference to the more recent Wyoming species of concern lrnown from BTNF (Heidel 2007). Note: Inforn1ation on the flora and the rare species of adjoining areas (Grand Teton National Park and Targhee National Forest) was provisionally considered for cross-referencing in early stages of project-planning. However, the merit of including species that might possibly be found on BTNF but have not been documented has less merit compared to fioristic inventories on the BTNF.
The process did not focus on those species that are cunently designated sensitive by the U.S. Forest Service Region 4 or by BTNF (Table 1; next page). However, they appear throughout the lists of prospective species of concern and species of interest by all three methods. In addition to the twelve species listed on this table, it deserves mention that there are an additional eight species designated sensitive by USFS R4 that are in Wyomi11g but not known :from BTNF, including meadow pussytoes (Antennaria arcuata), sweet-flowered rock-jasmine (Androsace chamaejasme ssp. carinata), meadow milkvetch (Astragalus diversifolius), park milkvetch (Astragalus leptaleus), upwai·d lobed moonwo1i (Botrychium ascendens), stemless beardtongue (Penstemon acaulis), Green River greenthread (Thelesperma cespitosa), a11d Uinta greenthread (Thelesperma pubescens).

· The most comprehensive versions of potential SOC and SOI lists are in the following pages, produced from the compilation of all species known from BTNF generated from floristic checklists that might meet SOC and SOI list terins (Table 3 and Table 4, respectively). All nomenclature follows Dom (2001), all county of distribution is based on documentation represented in Dorn (2001), and distribution within BTNF is cross-referenced by the three floristic studies areas, including Gros Ventre (Hartman and Nelson 1994), Salt and Wyoming Ranges (Hartman 1995) aI).d west slope of the Wind River Range (Fertig 1992). ·
The NatureServe SOC and SOI candidate lists for all species on BTNF are in Appendix A and B. The Wyoming plant species of concern list split into SOC and SOI candidate lists for .those species known from BTNF are in Appendix C and D). The lists . in this rep01i body and in the appendix are also submitted as excel spreadsheets on an accompanying CD for use by BTNF.

27 Finally, the master list of 1386 vascular plant species that have been documented from the BTNF is included (Appendix E). This flora include·s 1259 native species and 129 non-native species. Of the native species, (5.4%) are potential candidates on the edited SOC list and (22.3%) are potential candidates on the edited SOI list.
DISCUSSION
The length of these lists highlights the vascular plant diversity of the Bridger Teton National Forest, with almost half of the known species in the state (1386 species, among 2800 species as reported in Dorn 2001 ). It also reflects the current status of documenting species' rarity in Wyoming.
Possible considerations when reviewing SOC list candidates include Table 3 inforination such as Grank: values (consider whether to include G3G4), extent of distribution in BTNF (consider whether to include intermontane basin species) and extent of distribution in BTNF compared to the rest of its range. Possible considerations when reviewing SOI list candidates include Table 4 information similar to the above._ There are only a couple species on the SOI list that might be inappropr_iate for SOI status on the BTNF because of their "weedy" response to disturbance (e.g., Chenopodium capitatum, C. leptophyllum).
The biggest set of factors in assigning ranks for plants in Wyoming is their rarity, including number of discrete records, area of occupied habitat, and geographic extent of. the total range. In Wyoming, the largest single body of information available for assessing rarity is represented by specimens, deposited at the Rocky Mountain Herbarium (RM), representing the number of discrete areas and geographic extent. Much of the known distribution data for the state flora is posted in the Atlas of the Vascular Plants of Wyoming (Haiiman ai7.d Nelson 1998) at: http://vvwvv.rmh.uw:yo.edu/ .. Species that are known from less than 20 discrete areas in Wyoming are generally assigned a state rank of S2, but are not tracked unless they are rare throughout their range (regional or local endemics), l1ave biogeographic significance as disjuncts; or are otherwise identified.as vulnerable or under threats. Figures 1-4 are a representative set of Wyoming distribution maps for prospective SOC species in Table 2. Astragalus paysonii is a montane species that has a major part of its entire distribution in Wyoming and BTNF, Heterotheca depressa is a montane species that has a major part of its entire distribution in Wyoming but little in BTNF, Oryzopsis contracta (syn. Achnatherum contractum) is an . intennontane species that has a major part of its entire distribution in Wyoming but little of it in BTNF, and Saussure a weberi is an alpine species that has a major part of its entire distribution in Wyoming and in BTNF. ·

In addition, all Wyoming plant species of concern have a "Wyoming contribution rank" added to·them. This rank is a measure of Wyoming's contribution to the rangewide persistence of each species, reflecting how much of a species' range occurs in Wyoming relative to its entire distribution. These ranks are presented in the WYNDD export (Appendix C and D) for reference.
There are many other resources for screening prospective SOC and SOI species. Some species were discussed in a previous report on Wyoming plant species of concern submitted for consideration by the US Forest Service Region 4 (F~1tig 2000). An annotated copy of the report accompanies this report. The 79 species of BTNF in this report were divided into tln·ee categories and the high priority species correspond with the

29 prospective SOC list. Species profiles were prepared in the report, highlighting the following:
• Number of occurrences in Wyoming • Abundance • Range ~ Trends • Protection status • Threats • Public land units (managed areas) • Comments • References
This data was entered into WYNDD databases by Fe1iig, and used to produce state plant species abstracts that are posted on the WYNDD homepage (http://www.m\-:yo.edu/wvndd/). Each state species abstract has core field guide info1mation, abbreviated status report info1111ation, and a reference list for understanding the species and its status in Wyoming (see Astragalus paysonii example, Appendix F). Only by a review of this more detailed information can one consider, for example, that Astragalus paysonii is presently distributed mainly in human-disturbed sites like roadsides, but is thought to be associated with natural disturbance regimes and may be in decline historically due to fire suppression. In most all cases, the current ranking considerations stored at WYNDD are much the same as presented in Fe1iig (2000) with few exceptions ( e.g., Agoseris lackschewitzii, Asclepias crytoceras ssp. davisii, Carex parryana var. parryana, Hieracium scouleri and Salix eriocephala var. mackenzieana have Srank changes and are no longer tracked based on expanded distribution information or other factors.)
Likewise, the references cited in each state species abstract represent the major known status evaluations. In addition, the state species abstracts will be updated to . include a cros~-reference of all the conservation assessments prepared for the U.S. Forest Service the Rocky Mountain Region 2 as they address 72 vascular plant species of Wyoming (posted on the USFS Region 2 homepage), many of which are also in BTNF.
This review of the entire BTNF flora generated much higher numbers of potential candidate species because the entire flora has been assigned state ranks in Wyoming based on available distribution information. The state flora has been screened further in determining state species of concern. Many of the G3-level species that are not tracked 1 were previously tracked as state species 6f concern at one time but were determined to be more common than previously known and under no discerned threats. Many of the S2- level species that are not tracked were screened in the Wyom{ng species of concern list preparation and determined to be at the periphery of their range with limited potential for Wyoming to contribute to their rangewide status, particularly for species of broad ecological amplitude, low habitat tlu·eats, low species' vulnerability and/or high levels of protection.
30 There are no SOC omissions in the prospective SOC (Table 2) compared with the SOC lists generated by the other two methods (Appendix A and C) apart from the kinds of_cases represented below that generally represent taxonomic matters or distribution corrections.
Table 5. _Disparities between potential SOC species lists by different methods
Astragalus G2 SH Yes It is not known from BTNF though known diversifolius mil kvetch historically in Wyoming and present on USFS lands in Idaho. This species generally occurs at elevations generally lower than BTNF boundaries. Carex stenoptila River-bank G3 S2 N Specimen verifications are needed to further sedge evaluate state and -global status ranks.
Chaenactis alpina Alpine G3G4Q S3 N The taxon is no longer recognlzed by Wyoming var. !eucopsis dusty-·. botanistis (Dom 2001 ). maiden Physaria Creeping G3G4 S2 No More recent studies have rejected the taxonomic integrifolia var. bladderpod T2T3Q validity of this variety while the species is a monticola regional endemic that may still warrant SOC consideration Symphyotrichum ·smooth G3 S3 Yes The identification of the only specimen from mo/le (Aster aster BTNF is held in question, and may possibly mollis) represent a hybrid rather than species. This form of uncertainty may warrant separate consideration.
Regardless of the approach taken by the BTNF in producing final SOC and SOI lists,_the process and this compilation rep01i contribute to an understanding ofBTNF botanical resources and to the process of info1med natural resource programs.
