Smith Date of Review: 28may2016 Forest concurrence (or Yes recommendation if new) for inclusion of species on list of potential SCC: (Enter Yes or No) Forest review result: The Forest concurs or recommends the species for inclusion on the list of potential SCC: Yes_X__ No___ Rationale for not concurring is based on (check all that apply): Species is not native to the plan area _______ Species is not known to occur in the plan area _______ Species persistence in the plan area is not of substantial concern _______ Issue: Whether the species identified above should be listed as a species of Conservation Concern (SCC) for the Manti-La Sal National Forest (MLNF) as identified in the 2012 Planning Rule (36 CFR 219). Rule: The 2012 Planning Rule [36 CFR 219.7(c)(3)] states that “The regional forester shall identify the species of conservation concern for the plan area in coordination with the responsible official.” It [36 CFR 219.9(b)(2)(c)] defines a species of conservation concern as “…a species, other than federally recognized threatened, endangered, proposed, or candidate species, that is known to occur in the plan area and for which the regional forester has determined that the best available scientific information indicates substantial concern about the species’ capability to persist over the long-term in the plan area.” Analysis: The best available scientific information (BASI) indicates that the species is of local conservation concern. Conclusion: Based upon the BASI documented herein, it is recommended that this species be included in the potential list of SCC for the MLNF. 1 Intermountain Region Species of Conservation Concern Review DRAFT Template Species: _La Sal daisy______________ FOREST REVIEW INFORMATION Status summary based on other methods (information is on the Regional Office list of species considered; correct as needed): Entity Status/Rank (include definition if Other) NatureServe G2/N2 (NatureServe 2015) Natural UT - No Conservation Status Issued (Franklin and UDNR 2005) Heritage CO – Not Listed (CNHP 2015) Program State List UT - S2 (NatureServe 2015) Status CO – Not listed (NatureServe 2015) Not included in the CO or UT Wildlife Action Plans (SWAP 2015, WAP 2015) USDA Forest Erigeron mancus is currently a FS Region 4 sensitive species for the Manti Service La-Sal National Forest (USFS 2013).

Yes_X__ No___ 1) If no, provide explanation. 3. Substantial concern for species persistence in the plan area a. Describe briefly the distribution, abundance, and population trend of the species in the plan area. This alpine daisy is endemic to the La Sal Mountains (Welsh et al 1993). It occurs on the peaks above timberline in grass-sedge and forb communities at elevations of 9,900-12,200 feet. Within its narrow habitat, it is locally abundant. A study in 2008 did not find evidence for widespread impacts on the alpine turf habitat in the middle group of the La Sals (Smith 2008). The impact study plots were re-sampled in 2015, and while some localized impacts were recorded, there was no evidence of widespread adverse effects (Wild Utah Project 2015). Monitoring of alpine vegetation, focused on La Sal daisy and associated cushion plant species, was initiated in 2014 in response to the introduction of non-indigenous mountain goats (MLNF 2016). Additional research on the elevational distribution of La Sal daisy and associated species was conducted to establish baseline information on the 3 Intermountain Region Species of Conservation Concern Review DRAFT Template population and identify potential climate change impacts (Fowler and Smith 2010). The elevational transect was resampled in 2015, and preliminary analysis of the data shows no change in population density or elevational centroid (Smith and Fowler 2015). b. Describe briefly threats or risk factors to the species or the ecological conditions that support it (i.e. habitat) based on best available scientific information. Increasing recreational activity was identified as a potential threat by Franklin and UDNR (2005). The narrow alpine habitat of the La Sal Mountains is experiencing increased traffic by recreational users and introduced mountain goats (MLNF 2016, Smith and Fowler 2015, Wild Utah Project 2015). Trampling, excessive grazing and other localized site disturbance could have adverse impacts to the population. The combination of the effects of climate change could compound with the effects of other threats (NatureServe 2015). A portion of the habitat on the northern portion of the peaks has patented mining claims with a potential for exploratory activities in the future. c. Considering the trend in populations or habitat and threats or risk factors for those populations or habitats, is there substantial concern for persistence of the species in the plan area? The species appears locally abundant in suitable sites, but it is restricted to the narrow spine of the La Sal range. The limited alpine environment of the La Sal Mountains is experiencing increased use by recreationists, and may be impacted by grazing, trampling and climate change.

    ERIGERON MANCUS (ASTERACEAE) DENSITY AS A BASELINE TO DETECT FUTURE CLIMATE CHANGE IN LA SAL MOUNTAIN HABITATS James F. Fowler Barb Smith USFS Rocky Mountain Research Station USFS Manti-La Sal National Forest Flagstaff, Arizona 86001, U.S.A. Moab, Utah 84532, U.S.A. [email protected] ABSTRACT The La Sal Daisy, Erigeron mancus Rydb., is endemic to timberline and alpine habitats of the La Sal Mountains in Utah, an insular, lac- colithic mountain range on the Colorado Plateau in southeastern Utah. It occurs in alpine herbaceous communities from timberline to the crestline of the La Sals. Our primary goal in this study was to measure basic population biology parameters for the E. mancus population on the ridge from Mt. Laurel in the Middle Group of the La Sals west to treeline. We measured both E. mancus density and vascular plant species composition within 1-m × 1-m square frames along a ridgeline transect in mid-July near peak flowering time. Mean density was 7.09 plants/m2 which yielded a population estimate of over 200,000 plants along Mt. Laurel ridge and its nearby southern crestline. Density does not appear to change significantly with elevation since the standard errors of the density estimates of the three main patches overlap. The elevation of the sampled E. mancus population centroid weighted by E. mancus density was 3537 m (12,330 ft) which is within the largest patch near a shallow windswept saddle. Vascular plant diversity along the Mt. Laurel ridge transects averaged 17 ± 0.58 SE species per square meter with a richness range of 10–26 species per square meter.

    GEOGRAPHICAL Liliana Katinas,2 Jorge V. Crisci,2 Warren 3 4 DIVERSIFICATION OF L. Wagner, and Peter C. Hoch TRIBES EPILOBIEAE, GONGYLOCARPEAE, AND ONAGREAE (ONAGRACEAE) IN NORTH AMERICA, BASED ON PARSIMONY ANALYSIS OF ENDEMICITY AND TRACK COMPATIBILITY ANALYSIS1 ABSTRACT Tribes Epilobieae, Gongylocarpeae, and Onagreae, a monophyletic branch in the family Onagraceae, comprise genera endemic to or having their major basal radiation in the Madrean Floristic Region of southwestern North America. Parsimony analysis of endemicity (PAE) and panbiogeography (track compatibility analysis) were performed in order to seek an historical explanation for the patterns of high diversity and endemicity for the group in this region. Twenty- one areas of endemism are delimited, based on previous biogeographic schemes and presence of endemic plant and animal taxa. Based on distributional data on 173 species, a strict consensus PAE cladogram shows four main groups of areas: northern North America, the central Mexican areas, western North America, and eastern North America. Track compatibility analysis resulted in two strongly supported generalized tracks: one includes eastern North America, and the other western North America. PAE and panbiogeographical analyses of the distributional patterns of these taxa suggest a close relationship of eastern and western North America, with both areas more related to the Neotropics than to the Palearctic, and a rather weak association between northern North America and Asia. The discovery of two tracks in eastern and western North America for Epilobieae, Gongylocarpeae, and Onagreae reveal little relationship of North America with Asia or other continents. These tribes display a distinct but contemporaneous biogeographical history that differs from those of the Holarctic.

  • Manti-La Sal National Forest Potential Species of Conservation Concern (SCC) Review Procedural Report
    Manti-La Sal National Forest Potential Species of Conservation Concern (SCC) Review Procedural Report Tiffany Cummins Wildlife Biologist June 2, 2016 POTENTIAL SCC REVIEW PROCESS AND CRITERIA Potential SCC Review Process The 2012 Planning Rule (36 CFR 219.7(c)(3)) states that, “The Regional Forester shall identify the species of conservation concern for the plan area” (DOA 2012). The FSM 1921.01(2015) states that the Regional Forester will, “Identify, in coordination with Responsible Official, the species of conservation concern….” In keeping with these directives, resource specialists on the Manti-La Sal National Forest (MLNF) have been working closely with resource specialists from the Intermountain Regional Office (RO) to develop a potential list of SCC for the MLNF. Once the Regional Forester makes a final determination for this list of potential SCC species, it will be sent out for public review and comment. Once public comments are reviewed, the Regional Forester, in coordination with MLNF will develop the MLNF’s SCC List for the Forest’s current Forest Plan Revision effort. This coordinated evaluation effort resulted in a two-phase filter process for all species known to occur on the MLNF. Phase-1 of the filter process was a coarse-filter that was implemented by the RO resource specialists in early 2016. Criteria outlined in the FSH 1909.12 (10)(12.52d) was used to evaluate each species to determine if they qualified as either “must” or “should” be considered as a potential SCC (RO 2016). Species were broken into two preliminary potential SCC lists; a plant species list and a non-plant species list.

  • Classification of Subtribe Conyzinae (Asteraceae:Astereae)
    8 LUNDELLIA DECEMBER, 2008 CLASSIFICATION OF SUBTRIBE CONYZINAE (ASTERACEAE:ASTEREAE) Guy L. Nesom 2925 Hartwood Drive, Fort Worth, Texas 76109, USA Abstract: Subtribe Conyzinae includes Erigeron, New World Conyza, the North American genus Aphanostephus, and a small group of South American species segregated as the genera Apopyros, Darwiniothamnus, Hysterionica, Leptostelma, and Neja. Erigeron is the only genus with species native to regions outside of the New World. About 500 species are included in the subtribe. All North American, Central American, and South American species of Erigeron are included in the present treatment and assigned to one of the 35 sections recognized here. Ten new sections of Erigeron are recognized: sect. Disparipili, sect. Filifolii, sect. Gyrifolium, sect. Lonchophylli, sect. Meridionales, sect Microcephalum, sect. Quercifolium, sect. Radicati, sect. Rhizo- nexus, and sect. Terranea. Conyza is at least biphyletic; each of the groups is represented in the treatment but not all of the South American species are included. Molecular data have made it clear that traditional, North American species of Erigeron form the basal and terminal clades in the evolutionary topology of the subtribe, thus Conyza, Aphanostephus, and the other segregate genera have arisen from within the branches of Erigeron. Erigeron, as currently treated and tentatively maintained here, is paraphyletic. Broad taxonomic alternatives that include only monophyletic taxa are: (1) to treat the whole subtribe as Erigeron or, (2) to recognize Aphanostephus or Aphanostephus, Conyza, and the other South American segregates and at least an additional 5 to 10 new generic-level segregates from species groups traditionally treated as North American Erigeron. Keywords: Compositae, Conyza, Erigeron.

  • Erigeron Mancus Elevational Density Gradient As a Baseline to Detect Future Climate Change in Lasal Mountain Habitats
    Erigeron mancus elevational density gradient as a baseline to detect future climate change in LaSal Mountain habitats USFS Rocky Mountain Research Station, Flagstaff, AZ Manti-LaSal National Forest, Moab, UT James F. Fowler, RMRS Barb Smith, Manti-LaSal NF March 1, 2010 1 RESEARCH NEED AND QUESTIONS ADDRESSED The LaSal daisy, Erigeron mancus, is endemic to timberline and alpine habitats of the LaSal Mountains in Utah (Nesom 2006)(Fig. 1), an insular, laccolithic mountain range on the Colorado Plateau in southeastern Utah (Blakey and Ranney 2008). Erigeron mancus occurs in alpine herbaceous communities from timberline to the crestline of the Middle Group of the LaSals (Smith 2008) and is on the Forest Service Sensitive Plant Species List (USFS 2003). Prior to the current study little was known about the population biology of this species. Our study was conducted in and near the Mt. Peale Research Natural Area (RNA) which was established specifically to protect ecosystem structure and function in representative alpine and subalpine habitats. Research natural areas are part of a national network of ecological areas designated in perpetuity for research and education and/or to maintain biological diversity on National Forest System lands. Research natural areas are for nonmanipulative research, observation, and study. Forest Service objectives for these areas include protection against serious environmental disruptions and serve as baseline areas for measuring long-term ecological changes. The Manti-La Sal National Forest Land and Resource Management Plan (USFS 1986) requires management of the designated area with an emphasis on research, interpretation and protection against use that could jeopardize the diversity and pristine condition that led to original establishment of the RNA.

  • Utah Native Plant Society* Review of Manti-La Sal National Forest Species of Conservation Concern February 20, 2017
    Utah Native Plant Society* Review of Manti-La Sal National Forest Species of Conservation Concern February 20, 2017 *The Utah Native Plant Society is a Utah non-profit organization with an IRS 501(c)(3) status founded in 1978 with eight chapters in different areas of the state (including the Canyonlands chapter in southeastern Utah) and with over 400 members. E-mail address: [email protected]. Web site: www.unps.org ​ The Utah Native Plant Society (UNPS), in cooperation with the Grand Canyon Trust, is submitting this review of the plant species recommended by the US Forest Service Intermountain Regional Office (RO) as Species of Conservation Concern (SCC) for the purposes of land use planning by the Manti-La Sal National Forest (MLNF) in Utah. It appears that expert panels, academic and professional botanists and other stakeholders from the botanical community were rarely consulted or included in the development of the Forest SCC list, according to literature referenced. Retired US Forest Service (USFS) Regional Botanist Teresa Prendusi, and retired USFS Ecologist Wayne Padgett contributed their expertise to this review. Both have knowledge and experience with the national and regional rare plant programs, as well as species, and threats to those species, on the MLNF. From 1978 to 1992 UNPS held annual rare plant conferences and reviews and provided the primary input to the US Fish & Wildlife Service’s candidate species priority ranking program, and for the past almost 40 years has frequently informally consulted with the BLM, USFS and Utah Natural Heritage Program with respect to their various sensitive species programs, and provided input and recommendations.

  • Vascular Plant Flora of the Alpine Zone in the Southern Rocky Mountains, U.S.A
    VASCULAR PLANT FLORA OF THE ALPINE ZONE IN THE SOUTHERN ROCKY MOUNTAINS, U.S.A. James F. Fowler B.E. Nelson and Ronald L. Hartman U.S. Forest Service Rocky Mountain Herbarium Rocky Mountain Research Station Department of Botany, 3165 2500 S. Pine Knoll Drive 1000 E. University Ave. Flagstaff, Arizona 86001, U.S.A. Laramie, Wyoming 82071, U.S.A. [email protected] [email protected]; [email protected] ABSTRACT Field detection of changes in occurrence, distribution, or abundance of alpine plant species is predicated on knowledge of which species are in specific locations. The alpine zone of the Southern Rocky Mountain Region has been systematically inventoried by the staff and floristics graduate students from the Rocky Mountain Herbarium over the last 27 years. It is centered on the mountain ranges of Colorado and extends north to the Medicine Bow Mountains in southeast Wyoming and south into the Sangre de Cristo Range in north central New Mexico. It also includes the La Sal Mountains of Utah and the San Francisco Peaks in northern Arizona. The alpine meadow and treeline ecotone flora of the Southern Rocky Mountains includes 609 unique taxa of vascular plants comprising 581 species. The richest families are Asteraceae (104 species), Poaceae (58 species), Cyperaceae (57 species), and Brassicaceae (42 species). The central Colorado subregion is the most taxon rich (499) with richness tapering off to the north, southeast, and southwest. Non-endemic alpine zone taxa occur more frequently elsewhere in the Rocky Mountain Cordillera Floristic Region (515) than in the Madrean (373), Circumboreal (226), or North American Atlantic Floristic Regions (120).
